This research team used a laser sensor originally designed for autonomous vehicles to track debris flow surges.
Hazards & Disasters
Mapping the Fizzy Brines and Fluid-Filled Fractures Below a Volcano
Seismic tools reveal where hydrothermal fluids lie beneath the Uturuncu volcano in Bolivia and hint at their composition.
Artificial Lake-Level Lowering Alleviates Floods in the Himalayas
A new model combining future permafrost degradation and related avalanches demonstrates that artificial lake-lowering could significantly reduce the risk of glacial lake outburst floods.
Quantification of Subaerial Volcanism and its Products
Researchers estimate the mass of volcanic products that erupted above sea level from 1980 to 2019 by volcanoes worldwide and the average eruptive rates of each magmatic province.
Rapid Evolution of Volcanic Systems Reflected in Magnetics
Spatiotemporal magnetic monitoring along with InSAR models is a powerful tool to image magmatic, hydrothermal, and mechanical changes within the volcanic edifice of the Piton de la Fournaise.
Upscaling Slip and Friction From Grains to the Fault Core
Numerical simulations demonstrate how averaging deformations at the grain scale may unravel the macroscopic friction and unstable slip behavior of a fault core.
A New Measure of Roughness Could Advance Earthquake Geophysics
Scientists recently developed an alternative way to measure a rock’s roughness. It might help them understand the physics of faults.
Predicting Flood Conditions in the Next Few Years
Multiyear flood predictions are possible for watersheds in which the magnitude and frequency of flooding can be related to an atmospheric pressure see-saw in the North Atlantic region.
Summer Fire Means Winter Melt
Changing wildfire activity in California may impact seasonal hydrology by causing intense snowmelt during winter in areas where fires extend into higher elevation zones.
Seaports Could Lose $67 Billion Yearly from Natural Disasters
Small islands and low-income nations face the largest relative monetary losses to their ports and maritime trade.
