Flooding After Wildfires LA Faces Growing Risk Amid Climate Change

Breaking News, Climate Actions, Disasters, Environment

In the aftermath of devastating urban wildfires, a rainstorm might seem like a welcome relief. However, fire-scorched landscapes are highly vulnerable to floods, which can bring further destruction. Los Angeles has experienced this repeatedly, from the 1933 Griffith Park Fire to the 2009 Station Fire in the San Gabriel Mountains and the 2018 Woolsey Fire in Malibu. Mitul Luhar, an expert in fluid dynamics and associate professor of aerospace, mechanical, civil, and environmental engineering at USC, is studying these risks. At the City of Los Angeles's Hydraulic Research Laboratory in Frogtown, Luhar and his team have developed a 1:120 scale hydraulic model of a section of the L.A. River to simulate flood scenarios. Luhar explains why floods often follow wildfires and what engineers c...

Climate Change Made LA Wildfires 35% More Likely, Study Finds

Breaking News, Disasters, Fact Check

Los Angeles witnessed one of its worst wildfire outbreaks in January 2025, and according to a new World Weather Attribution (WWA) report, human-induced climate change played a key role in making the conditions 35% more likely. The fires, which began on January 7 in Palisades and Eaton counties, quickly spread, fueled by dry vegetation and strong Santa Ana winds. Over the following weeks, additional fires erupted in San Diego County, ultimately burning over 57,000 acres and causing 28 deaths. For the first time in history, global temperatures surpassed 1.5°C in 2024. The WWA report warns that if temperatures rise to 2.6°C by 2100, the likelihood of such wildfire-friendly conditions will increase by another 35%. Clair Barnes, a researcher at Imperial College London, emphasized how p...

Rising Debris Flow Risks Dangerous Link Between Wildfires, Rainfall, and Climate Change

Breaking News, Disasters, Fact Check

Debris flows, fast-moving masses of mud, rocks, and water, are becoming a growing concern in the United States, particularly in areas recently affected by wildfires. A map produced by the U.S. Geological Survey (USGS) highlights high-risk zones near Los Angeles after the Palisades Fire. The model simulates a scenario where 15 minutes of rainfall, at just under 1 inch (24 mm) per hour, could trigger debris flows in vulnerable regions. The landscape itself can create ideal conditions for debris flows. Steep slopes, the presence of clay-rich soil, and silt-sized particles in watersheds are key contributors. Generally, slopes gentler than 23 degrees and lacking fine-grain materials are less likely to experience debris flows. Post-wildfire conditions worsen the risk. Severely burned areas...

Deadly Threat Lingers as Rain Looms Over Los Angeles Wildfire Zones

Breaking News, Climate Actions, Disasters, Environment

While firefighters continue to battle wildfires in the Los Angeles area, another danger is fast approaching. Rain expected over the weekend of January 25–26 may help extinguish the flames, but it also carries the risk of triggering deadly debris flows in the burned hillsides. These fast-moving torrents of water, ash, and debris can wreak havoc, destroying homes, infrastructure, and lives in minutes. The phenomenon is not new to California. In 2018, the hills above Montecito, scorched by the Thomas Fire, gave way during a storm, unleashing a devastating debris flow that killed 23 people and damaged over 400 homes. Similar events now threaten wildfire-affected areas near Los Angeles, where experts warn that the conditions for another disaster are already in place. When wildfires scorch...

Wildfire Smoke Crisis in Los Angeles Millions Exposed to Toxic Air as Fires Rage

Breaking News, Disasters, Environment

Los Angeles, January 2025 – A wildfire crisis is gripping Los Angeles as fires sweep through homes, vehicles, and neighborhoods, blanketing millions in hazardous smoke. The blazes, which have already consumed thousands of structures, are not only destroying property but releasing a cocktail of toxic chemicals that pose severe risks to public health. As homes and urban infrastructure burn, materials like furniture, plastics, paints, and electronics ignite, emitting harmful substances into the air. According to a 2023 study, wildfire smoke from urban-wildland interfaces contains dangerous compounds, including hydrogen chloride, polycyclic aromatic hydrocarbons, and dioxins. It also carries heavy metals like lead, chromium, cadmium, and arsenic elements known to damage vital organs, includ...

DO NOT DRINK Notice in LA Wildfires Pose Dual Threat High Winds and Water Contamination Risks

Breaking News, Climate Actions, Disasters

As LA wildfires rage on, high winds are expected to worsen conditions, amplifying the destruction and raising new concerns about drinking water safety. Last week, Pasadena Water and Power issued its first-ever "Do Not Drink" notice to a third of its customers, citing the risk of toxic chemicals infiltrating the water supply after infrastructure damage. Although the advisory has since been lifted for most areas, the incident highlights the hidden dangers urban fires pose to water systems. Unlike wildfires in forests, urban fires wreak havoc on critical infrastructure. Andrew Whelton, a Purdue University professor, explains that ash, soot, and debris can enter water systems when pressure drops during a fire. Compounds released from burning synthetic materials are especially harmful, even ...

Mining Impact on Rivers Flood Risks in Dynamic Channels

Breaking News, Climate Actions, Environment, Thoughts & Talks

Rivers are often subjected to human interventions such as structural confinement and aggregate mining, which significantly alter their natural flow and topography. A recent study conducted on the gravel-bed Bislak River in the Philippines sheds light on how these activities influence river morphology, hydraulics, and flood risks. Using repeat, system-scale, high-resolution topographic surveys, researchers examined annual morphological changes in the Bislak River. They coupled this data with two-dimensional hydraulic modeling to simulate the impacts on flood risk. The findings highlight a complex interplay between human actions, sediment dynamics, and river hydraulics. Key Findings Sediment Dynamics and Topography Aggregate mining was found to export sediment from the river, lea...

January 2025 USA in Fire Los Angeles Disaster Wildfires Destroy Thousands of Homes

Breaking News, Climate Actions, Disasters, Environment

January 2025 has brought devastating wildfires to the Los Angeles area with investigators racing to uncover their origins. The fires, driven by fierce winds, have ravaged thousands of homes, leaving communities in ruins. Early findings suggest that human activities, utility infrastructure, or equipment failures may be to blame, as lightning was absent during the outbreaks. Human activities play a significant role in igniting these blazes. The deadly 2023 Maui fire, for example, began with a broken power line, while California’s largest fire in 2024 started when a burning car was pushed into a ravine near Chico, destroying over 700 structures. This year’s fires are yet another reminder of the devastating impact of human-related ignitions. Wildfires thrive on three elements: conduc...
