    Tropical Cyclones stalling along the North Atlantic coast lead to more rain in the confined location Jeu Juil 4 2019
    According to a new study by scientists from NASA and NOAA, tropical cyclones stall more frequently and stay longer near the coastline. This potentially leads to more precipitation over confined locations and thus an aggravation of tropical cyclone hazards for coastal populations. In the new study, scientists Hall and Kossin examined all tropical cyclones from 1944-2017 in the National Hurricane...

    Recent study presents new assessment method for rare floods risks Jeu Juil 4 2019
    A recent study, published in the Water Resource Research journal, presents a new method for a spatially realistic national flood risk assessment. Researchers expanded an existing statistical model, based on U.S. Geological Survey (USGS) river flow data, to simulate a thousand years of potential flood events. By calculating the damage for each event in dollars, they were able to estimate the...

    Review article discusses using remote sensing-based proxies to improve urban disaster risk management and resilience Ven Mai 31 2019
    Remote sensing, or obtaining information about the Earth’s surface from afar using satellites or high altitude aircraft, is an important tool for predicting, mitigating, and managing disasters. To obtain a more comprehensive view of the conditions on Earth, remote sensing analysts must often look beyond information that can be immediately extracted from satellite imagery, for example, and use...
