Displaying 15 of about 58 resultsUsing the Dartmouth Flood Observatory large flood data archive, this study aim s to assess the trend of flood occurrence in the Mainland Southeast Asia (MSEA) in 1985–2018, and quantify the associated impacts on humans. A differentiation that authors make is between landfall-induced floods (TCFloods) and floods by all causes (ALLfloods).

The training module on Urban Risk Reduction and Resilience focuses on various aspects of disaster risks in urban areas. Factors like the concentration of population, economic activities, building activities and networks in urban areas result in aggravated risk from disasters and at times, these factors end up causing disasters as well. The module is des…
The hazard to the city of Mumbai, India, from a possible severe tropical cyclone under the recent historical climate is considered. The authors first determine, based on a review of primary sources, that the Bombay Cyclone of 1882, documented in a number of print and Internet sources and claimed to have caused 100 000 or more deaths, did not occur. Two…
Latin America and the Caribbean (LAC) is the second most disaster-prone region in the world. Some 152 million people have been affected by 1,205 disasters (2000-2019).
Although many hazards are cyclical in nature, the hazards most likely to trigger a major humanitarian response in the region are sudden onset hazards such as earthquakes, hurricanes and…
Catastrophe models estimate risk at the intersection of hazard, exposure, and vulnerability. Each of these areas requires diverse sources of data, which are very often incomplete, inconsistent, or missing altogether. The poor quality of the data is a source of epistemic uncertainty, which affects the vulnerability models as well as the output of the cat…
The past is often the window to our future, especially when it comes to natural disasters. Using data from the 2018 floods that struck southwestern Japan to calibrate a machine learning model, researchers from the International Research Institute of Disaster Science (IRIDeS) at Tohoku University and the Japan-Peru Center for Earthquake Engineering Resea…
Climate change will make fast-moving storms more likely in late 21st-century Texas
By Jade Boyd
HOUSTON — (July 6, 2020) — Climate change will intensify winds that steer hurricanes north over Texas in the final 25 years of this century, increasing the odds for fast-moving storms like 2008’s Ike compared with slow-movers like 2017’s Harvey, accord…

The Sahara Desert is the world's biggest source of dust and in 2020, it broke the June record for sending the largest and thickest dust cloud toward the Americas.
Amato Evan, an atmospheric scientist at Scripps Institution of Oceanography at UC San Diego, and colleagues have broken down the conditions that led to what some researchers…

In just over a month’s time, the US Atlantic hurricane season will begin. This means a series of big storms may hit the country for around six months until the end of November. With the US currently facing more than one million cases of COVID-19 and a death toll of more than…

“Surprisingly, both Hurricane Laura and Hurricane Sally appeared to have similar setups to Hurricane Michael, with both storm events being preceded by smaller storms (i.e. Hurricane Hanna and Marco, respectively),” Dr. Brian Dzwonkowski said. “This pre-storm setup of the oceanic environment likely contributed to the int…

Hurricane Lane was an impactful event for the Hawaiian Islands. In August 2018, over a four-day period, Hawaiʻi Island received an average of 17 inches of rainfall, with a four-day single-station maximum of 57 inches, making Hurricane Lane the wettest tropical cyclone ever recorded in Hawaiʻi. A study published i…
In the midst of the 2020 Atlantic hurricane season, with storms forming in rapid sequence, records broken early in the season and four storms already producing significant damage in the Caribbean and U.S., whether we are headed for a record-breaking year is a good question. Various forecast agencies have issued mid-season updates, which signal prospects…

As hurricanes go, Sally was not especially powerful. Rated a Category 2 storm when it struck the Gulf Coast on Wednesday, it was soon downgraded. But climate change likely made it more dangerous by slowing it down and feeding it more moisture, setting it up to pummel the region with wind and catastrophic rainfall.

Hurricane Laura plowed through the heart of Louisiana’s oil and chemical industries as a powerful Category 4 storm, leaving a chlorine plant on fire and the potential for more hazardous damage in its wake.
The burning BioLab facility sent dark smoke and…

The trail of destruction left by Cyclone Amphan in eastern India has once again highlighted inadequacies in dealing with climate disasters that displace millions of people every year.
Despite improvements in early warning systems and disaster response infrastructure, India and other countries in South Asia are still grossly un…
