January 7: A magnitude 7.1 earthquake struck near Shigatse city in Tibet, resulting in at least 95 deaths and 130 injuries. The quake caused extensive damage to over 1,000 houses and affected approximately 62,000 residents. Tremors were felt as far as Nepal’s capital, Kathmandu, and the Indian state of Bihar.

On January 7, 2025, at 09:05 CST (UTC+8), a devastating earthquake measuring Mw 7.1 struck Tingri County in the Shigatse prefecture of Tibet Autonomous Region, China. The earthquake, which originated at a depth of 10 km (6.2 mi), was caused by normal faulting and became the most powerful seismic event in China since the Maduo earthquake in May 2021 and the deadliest since the Jishishan earthquake in December 2023. The tremors were felt across South Asia, impacting Nepal and northern India.

Tectonic Context

The Tibetan Plateau, formed due to the ongoing collision between the Indian and Eurasian tectonic plates, is highly seismically active. The region’s faulting mechanism includes both strike-slip and normal faulting. The earthquake’s rupture occurred on a north-south trending fault, identified as the Deng Me Cuo Fault, with a rupture length extending between Ngamring and southern Tingri County.

Casualties and Impact

The official Chinese government report cited 126 fatalities, but alternative estimates ranged from 134 to over 400. The discrepancy has fueled criticism and concerns regarding information transparency. At least 338 people sustained injuries, with 19 in critical condition. Nepal also reported 13 injuries, and minor damage occurred in northern India.

The earthquake led to the collapse of 3,612 homes and damaged over 27,200 buildings. In several villages, up to 90% of homes were razed, and infrastructure—including roads and hydropower dams—suffered significant damage. More than 40 monasteries were impacted, with eight severely affected. Telecommunications were briefly disrupted, and landslides damaged key transportation routes.

In Nepal, homes and a police station sustained damage, while avalanches near Mount Everest were reported. In Bhutan, tremors triggered two avalanches near the Bechung glacier.

Rescue and Relief Efforts

China mobilized over 14,000 rescue personnel, 340 medical workers, and extensive resources to aid the affected population. The Chinese government allocated 100 million yuan ($13.6 million) for disaster relief, deploying military personnel, drones, and satellites for damage assessment and response coordination. Emergency shelters were established, and relief supplies—including tents, warm clothing, and food—were distributed to displaced residents.

The Chinese Communist Party’s General Secretary, Xi Jinping, emphasized the urgency of rescue efforts, infrastructure restoration, and relocation assistance. Temperatures plummeting to −16°C (3°F) exacerbated the crisis, increasing the risk of hypothermia among survivors trapped under rubble.

By January 31, over 7,700 temporary shelters and nearly 10,000 tents had been set up, accommodating 47,787 displaced residents. Search and rescue operations concluded after two weeks, with authorities acknowledging the slim survival chances for missing persons due to extreme conditions.

International Response

The earthquake prompted global reactions, with leaders from more than 22 countries, the United Nations, and international organizations extending their condolences. The U.S., Denmark, and South Korea expressed sympathies via official embassy statements, while Taiwan’s Straits Exchange Foundation and Mainland Affairs Council conveyed formal messages of support. The 11th Panchen Lama initiated a donation drive that raised nearly 1.5 million yuan ($208,660) to support relief efforts.

Despite widespread solidarity, the Chinese government took action against misinformation, including administrative penalties for individuals spreading unverified fatality estimates and AI-generated images online.

Conclusion

The January 7 earthquake in Tibet stands as a tragic reminder of the seismic vulnerabilities in the region. The scale of destruction underscores the urgent need for improved earthquake-resistant infrastructure and enhanced disaster preparedness measures. While China’s rapid response mitigated further casualties, ongoing rehabilitation efforts remain critical for the thousands affected by this catastrophic event.

January 2025: Uncontrolled wildfires ravaged parts of Los Angeles, destroying hundreds of buildings, causing at least ten fatalities, and forcing around 180,000 residents to evacuate. The fires were fueled by strong winds and prolonged drought conditions. 

Los Angeles and San Diego County, California

A series of 14 catastrophic wildfires engulfed the Los Angeles metropolitan area and San Diego County from January 7 to 31, 2025, fueled by drought conditions, low humidity, and powerful Santa Ana winds. With wind gusts reaching up to 100 miles per hour (160 km/h), the fires led to widespread destruction, claiming at least 29 lives, displacing over 200,000 residents, and consuming more than 18,000 homes and structures. In total, the wildfires burned approximately 57,000 acres (23,000 ha; 89 sq mi) of land.

Major Fires and Emergency Response

Among the most devastating fires were the Eaton Fire in Altadena and the Palisades Fire in Pacific Palisades. These two blazes, fully contained by January 31, ranked as the second and third-most destructive fires in California’s history. Firefighting efforts were led by municipal fire departments and the California Department of Forestry and Fire Protection (CAL FIRE), with both ground teams and tactical aircraft deployed to combat the flames.

Forecasted Disaster and Climatic

Conditions

The National Interagency Fire Center (NIFC) had warned of “above normal significant fire potential” as early as January 2. By January 7, the Storm Prediction Center (SPC) had issued an extreme fire weather warning for Southern California, marking multiple days of critical fire risk. As the fires spread, the National Weather Service (NWS) declared a red flag warning for Los Angeles and Ventura counties, citing dangerously dry conditions exacerbated by a transition from El Niño to La Niña, which left the region in a moderate drought by late December 2024.

Climate Change and Fire

Intensification

Scientific analyses from the Institut Pierre Simon Laplace and Climate Central indicated that anthropogenic climate change had intensified the fire conditions, contributing to increased temperatures, erratic rainfall, and prolonged dry seasons. Researchers found that rising urban temperatures and decreased precipitation heightened wildfire risks, while shifts in seasonal weather patterns extended the fire season further into the months dominated by Santa Ana winds.

Unprecedented Wind Conditions

The Santa Ana winds that fueled the fires reached exceptional speeds, with gusts recorded at 100 mph (160 km/h) on Mount Lukens and 98 mph (158 km/h) in the Santa Monica Mountains. The NWS described the windstorm as potentially “life-threatening,” with widespread power outages and downed trees reported across the region. By January 7, reports from Magic Mountain Truck Trail in Santa Clarita confirmed wind speeds of 84 mph (135 km/h), leading the NWS to compare the event to the region’s most destructive windstorm since 2011.

Compounding Human Factors

Budgetary Constraints on Firefighting Efforts

The Los Angeles Fire Department (LAFD) faced operational challenges due to a $17.6 million budget reduction for the 2024–2025 fiscal year. Fire Chief Kristin Crowley noted that these cuts severely impacted emergency response preparedness and brush clearance inspections. Additionally, rising costs and delays in acquiring new fire trucks hindered fire departments across the United States.

Aging Infrastructure and Construction Codes

Older neighbourhoods, particularly in the Palisades, suffered extensive damage due to outdated building codes. Many homes, built in the 1950s and 1960s, lacked modern fire-resistant materials, making them more susceptible to ignition.

Electric Grid Vulnerabilities

Los Angeles’ power grid was ill-equipped to handle the extreme wind conditions, with infrastructure designed to withstand only up to 56 mph (90 km/h) winds. Experts criticized the Los Angeles Department of Water and Power (LADWP) for not implementing proactive power shut-offs to prevent electrical fires.

Homelessness and Fire Incidents

A growing number of fires in Los Angeles were linked to homelessness. By 2024, an average of 46 homeless-related fires occurred daily, worsening an already precarious fire safety situation.

Water Supply Shortages

Firefighters faced critical water shortages as storage tanks in high-elevation neighborhoods were depleted faster than they could be refilled. The Santa Ynez Reservoir, a crucial water source for Pacific Palisades, had been emptied for maintenance, significantly reducing available water pressure during the emergency.

Preparation and Government Response

Governor Gavin Newsom mobilized 65 fire engines, seven helicopters, and over 100 personnel in response to the growing crisis. The Mayor of Los Angeles, Karen Bass, issued warnings to residents and coordinated emergency operations. However, as she was attending the inauguration of Ghanaian President John Mahama, acting mayor Marqueece Harris-Dawson oversaw local efforts. Utility providers, including Southern California Edison and San Diego Gas & Electric, preemptively cut power in high-risk areas to mitigate potential ignitions.

Lead-up and Early Impact

On January 7, Los Angeles declared a state of emergency. The South Coast Air Quality Management District (AQMD) issued dust storm warnings, while power outages left over 20,000 customers in the dark. The National Weather Service called the event the strongest windstorm of 2025, while the Federal Aviation Administration issued temporary flight restrictions due to hazardous conditions.

Conclusion

The January 2025 wildfires stand as one of the most severe climate disasters in recent California history. The combination of extreme wind, prolonged drought, and inadequate infrastructure response underscores the urgent need for climate-adaptive policies, improved fire management funding, and enhanced urban planning to mitigate future wildfire disasters.

January 15, 2025: Heavy rains caused flooding in coastal cities of southern Brazil, including Balneário Camboriú and Itapema. The floods led to the displacement of entire communities and significant damage to infrastructure. 

January 2025 – Vale do Aço, Brazil — The metropolitan region of Vale do Aço, located in the interior of Minas Gerais, Brazil, faced a catastrophic natural disaster between January 12 and 13, 2025, as extreme precipitation led to severe floods and landslides. The heavy rains resulted in significant devastation across the four municipalities in the region—Coronel Fabriciano, Ipatinga, Santana do Paraíso, and Timóteo—with Ipatinga experiencing the most substantial impact.

Unprecedented Rainfall and Landslides

The torrential rains, attributed to the South Atlantic Convergence Zone (ZCAS), triggered widespread flooding and landslides across the region. Ipatinga, the hardest-hit city, recorded ten fatalities caused by landslides, including two children. Coronel Fabriciano and Santana do Paraíso each reported one fatality. In total, more than 180 people were left homeless, with thousands affected by the disaster.

Rain gauges installed by the National Center for Monitoring and Early Warning of Natural Disasters (CEMADEN) reported extreme rainfall levels. In Ipatinga’s Betânia neighborhood, over 200 millimeters (7.9 inches) of rain fell within six hours, nearly equaling the city’s monthly average rainfall for January. Similar levels of rainfall were recorded in neighbouring municipalities, exacerbating the crisis.

Widespread Destruction and Infrastructure

Collapse

The floods caused landslides that buried homes, particularly in the neighbourhoods of Betânia, Canaã, and Vila Celeste in Ipatinga. One particularly tragic incident saw five members of a single family killed when a slope collapsed onto their home in Betânia. In Santana do Paraíso, landslides obstructed roads, cutting off access to Mesquita and Bom Jesus do Bagre.

Infrastructure damage was extensive. In Ipatinga, the Unidade de Pronto Atendimento (UPA) in the Canaã neighborhood was inundated, forcing patient evacuations to neighboring healthcare facilities. Commercial districts suffered immense losses, with Avenida José Selim de Sales, a primary business hub, heavily impacted. Even after floodwaters receded, mud and debris coated streets, homes, and businesses, hampering recovery efforts.

Public transportation and major roadways also suffered disruptions. The urban section of BR-381 was completely submerged near Shopping Vale do Aço, halting traffic. Similarly, Avenida Maanaim sustained severe structural damage due to the overflowing Taúbas stream. In Coronel Fabriciano, a slope threatened to collapse, leading to the closure of Avenida Rubem Siqueira Maia, a key roadway.

Emergency Response and Displacement

The Civil Defense issued emergency alerts to residents via mobile notifications and sirens, warning of further landslides and flooding. Despite these measures, the rapid onset of the disaster left many vulnerable. By January 15, the death toll from the broader rainy season across Minas Gerais had climbed to 26, with approximately 130 individuals left homeless in Ipatinga alone and 400 displaced. The floods affected over 85,000 people in the region by January 14.

Timóteo faced its own challenges, as a landslide isolated part of the city and flooded the Fórum Geraldo Perlingeiro de Abreu courthouse. Around 260 families in the municipality were affected, many requiring urgent assistance.

Historical Context and Urban Vulnerability

The Região Metropolitana do Vale do Aço is characterized by rugged terrain and high population density in informal urban settlements. Decades of unplanned urban expansion have forced residents to build homes near watercourses and on unstable slopes, significantly increasing their vulnerability to natural disasters. This lack of adequate land-use planning has made flooding and landslides recurrent threats.

Less than a month before the January 2025 floods, Coronel Fabriciano had already suffered a devastating storm in December 2024, which left more than 1,000 people homeless or displaced. The compounding effects of these extreme weather events underscore the urgent need for improved disaster risk management and infrastructure resilience in the region.

Looking Ahead: Recovery and Mitigation Efforts

As recovery efforts continue, local authorities and humanitarian organizations are working to provide aid to affected residents. The floods have reignited discussions on the necessity of sustainable urban planning and enhanced early-warning systems to mitigate future disasters.

The Vale do Aço floods of January 2025 serve as a stark reminder of the escalating risks posed by extreme weather events in vulnerable urban areas. With climate change expected to increase the frequency and intensity of such phenomena, a concerted effort toward disaster preparedness and resilient urban development is more critical than ever.

Late January to February 2025: Over 12,000 earthquakes, mostly of small magnitude, were detected near Greece’s volcanic island of Santorini. The seismic activity prompted authorities to declare a state of emergency, leading to evacuations and heightened monitoring due to concerns about a potential larger earthquake.

The ongoing swarm of earthquakes near Santorini continues to perplex scientists while keeping disaster risk management teams and the public on high alert. Reports of the escalating seismic activity have garnered global attention. Santorini, a vast volcanic caldera with two small islets at its submerged center, has a turbulent volcanic history spanning 650,000 years. The island has experienced catastrophic eruptions, including a devastating blast around 1560 B.C. that contributed to the collapse of a civilization, a significant eruption in A.D. 726, and a moderate one in 1950. Given its active volcanic status, the region remains under close scrutiny.

Since January 31, 2025, seismic activity has surged across a 250 km² area northeast of Santorini, near the fault believed responsible for the July 9, 1956, Amorgos earthquake and tsunami. This has raised concerns among experts, who are closely monitoring the evolving situation. According to a report dated February 9, prepared by Prof. Ahmet Yalciner and a team of experts in collaboration with the National Observatory of Athens (NOA), over 1,200 earthquakes have been recorded between January 25 and February 7, with magnitudes ranging from 1.0 to 5.2. Among these, 129 earthquakes exceeded magnitude 4.0, with the strongest recorded at ML 5.2. Most quakes occurred at depths between 10 and 15 km, forming a NE-SW trending cluster east of Anydros Island.

The seismic activity is cantered within the Anydros Uplift (Anydros Horst), positioned between the NW-dipping Anydros Fault and the SE-dipping Santorini-Anafi Fault. Initial data analysis indicates an increase in earthquake magnitudes during the early phase of the swarm.

Tsunami modelling studies have been undertaken to assess potential risks associated with tectonic and volcanic activity in the region. The simulations examine possible tsunami scenarios affecting the islands of Santorini, Amorgos, Astypalaea, and Anafi, with a particular focus on the Aegean coast of Türkiye.

Growing Public Concerns and Evacuations

Denis Chang Seng, UNESCO-IOC Programme Specialist and Technical Secretary of ICG-NEAMTWS, emphasized that beyond scientific debate over the causes, a crucial issue demanding attention from disaster risk management and response teams is the self-initiated evacuation of Santorini residents. Human risk perception plays a pivotal role in such scenarios, influenced by proximity to the perceived hazard, past disaster experiences, and public trust in authorities. Although individual factors such as media coverage, age, gender, education, and income levels may not be primary drivers of risk perception, they can amplify core factors influencing public response.

According to BBC News, by February 6, over 11,000 people had fled Santorini—7,000 via ferry and 4,000 by air—due to the escalating situation. In response, Greece declared a state of emergency for Santorini on February 5, following a 5.2-magnitude earthquake at 21:09 local time (19:09 GMT) between Amorgos and Santorini. The emergency decree, effective until March 3, aims to address urgent needs and manage the situation. Greek Prime Minister Kyriakos Mitsotakis reassured the public, stating, “All plans have been implemented. Forces have been moved to Santorini and the other islands so that we are ready for any eventuality.” Despite heightened seismic activity, no significant damage has been reported on the island thus far.

The Role of the

UNESCO-IOC Tsunami Warning and Mitigation System

Amid the unfolding seismic activity, the importance of the UNESCO-IOC Intergovernmental Coordination Group for the Tsunami Early Warning and Mitigation System in the North-Eastern Atlantic, the Mediterranean, and Connected Seas (ICG-NEAMTWS) has come to the forefront. This system coordinates tsunami risk management across 40 member states with access to the Mediterranean, Baltic, North, and Black Seas. Currently, the system is designed to detect and respond to seismic-driven tsunamis, with ongoing efforts to expand its scope to include non-seismic tsunamis, such as those caused by volcanic eruptions and landslides.

To enhance coordination, the UNESCO-IOC Technical Secretary of ICG-NEAMTWS has requested its Steering Committee, composed of representatives from multiple countries, to share insights on the evolving situation. A dedicated, independent communication channel has been established between the Technical Secretary, the Hellenic National Tsunami Warning Center (HL-NTWC) at NOA, and Türkiye’s Kandilli Observatory and Earthquake Research Institute (KOERI) to facilitate the rapid exchange of critical information, particularly during nighttime and weekends.

Furthermore, NEAMTWS Tsunami Service Providers are organizing a meeting to review operational procedures and communication strategies for member states, with special attention to non-seismic tsunami events. Additionally, experts are considering a closed scientific meeting to assess the evolving seismic activity near Santorini. In response to the growing concerns, the Hellenic National Tsunami Warning Center (HL-NTWC) swiftly installed a new tide gauge station at Pori on Santorini’s northeastern coast. This new station is expected to significantly enhance sea-level monitoring and strengthen early warning capabilities.

Looking Ahead

With different schools of thought on the causes and triggers of the ongoing earthquake swarm, continued research and monitoring will be key in reaching a scientific consensus. The situation remains dynamic, and disaster risk professionals will continue to emphasize preparedness, timely communication, and proactive measures to ensure public safety in Santorini and the surrounding region.

February 26 – March 9, 2025 A wildfire began in Ōfunato, Iwate Prefecture, Japan, covering a significant area before being extinguished on March 9. It destroyed 171 structures, resulted in one fatality, and forced over 4,500 people to evacuate. This was the largest wildfire in Japan in over 50 years. 

Largest Wildfire in Japan in 50 Years Devastates Ōfunato

Ōfunato, Japan — A massive wildfire that broke out on February 26 in the city of Ōfunato, Iwate Prefecture, has been extinguished after burning for 12 days, marking Japan’s largest wildfire in over 50 years. The blaze, which consumed approximately 2,900 hectares (7,166 acres), destroyed 171 structures, resulted in one fatality, and forced the evacuation of 4,596 residents.

Severe Drought Conditions Fuel Disaster

The fire erupted in Akasaki Town during Ōfunato’s dry season, following Japan’s hottest recorded year in 2024. The region had received only 2.5 mm of rainfall in February-a historic low compared to the 41 mm average. Experts attributed the rapid spread of the fire to the area’s dry conditions, steep mountainous terrain, and highly flammable coniferous trees.

Fire’s Rapid Spread and Evacuation Orders

The wildfire was first reported at 1:02 p.m. on February 26. Within hours, evacuation orders were issued, initially affecting the Ryōri area. By the evening, the fire had expanded to 600 hectares, with 84 structures damaged and more than 2,000 people displaced.

As the fire raged on, authorities extended evacuation orders to multiple districts. By March 1, nearly 1,900 households had been affected, with the blaze spreading to 1,400 hectares. The fire continued growing, reaching 2,900 hectares by March 5. The following day, authorities confirmed that it had surpassed Japan’s previous record for wildfire size, set in Hokkaido in 1975.

Efforts to Contain the Fire

Firefighters from 15 prefectures, totalling 2,030 personnel, along with 13 aerial firefighting teams, battled the flames. The Japan Self-Defence Forces were deployed, and disaster relief measures were enacted to aid displaced residents.

Rainfall on March 5 provided a crucial break in firefighting efforts, although officials noted that the fire remained a threat. Evacuation orders were lifted gradually, with 957 residents allowed to return on March 7, and the final orders lifted on March 10.

Casualties and Impact

The fire claimed the life of a 90-year-old man whose body was discovered on February 27. In addition to the 171 structures destroyed, another 39 buildings sustained damage. Electricity was cut to 500 households, and several schools and businesses, including Taiheiyo Cement’s Akasaki plant, suspended operations. Transportation was also disrupted, with sections of Sanriku Railway closed and road access restricted.

The fishing industry suffered significant losses, with multiple processing plants destroyed and fishermen losing vital equipment. Additionally, nearly 3,000 chickens perished due to lack of food and water while their facilities were inaccessible.

Government Response and Recovery Efforts

The Japanese government declared the wildfire a “severe disaster,” unlocking financial assistance for rebuilding efforts. Prime Minister Shigeru Ishiba pledged support for affected communities. By March 6, Ōfunato had received over 3,600 donations, amounting to approximately ¥160 million (US$1.46 million), with contributions from high-profile figures, including baseball star Roki Sasaki and the Los Angeles Dodgers.

With the fire now fully contained, recovery efforts are underway to rebuild homes, businesses, and infrastructure in Ōfunato. The cause of the wildfire remains under investigation.
