Mantle heat may have boosted Earth's crust 3 billion years ago

Phys.org: Earth science - Wed, 04/24/2024 - 19:06
Little is known about the nature and evolution of Earth's continental crust before a few billion years ago because cratons, or stable swaths of the lithosphere more than 2–3 billion years old, are relatively rare.

Current levels of coastal flood risk are projected to increase in coming decades due to various reasons, e.g. sea-level rise, land subsidence, and coastal urbanization: action is needed to minimize this future risk. We evaluate dykes and coastal levees, foreshore vegetation, zoning restrictions, and dry-proofing on a global scale to estimate what levels of risk reductions are possible. We demonstrate that there are several potential adaptation pathways forward for certain areas of the world.

This paper presents the development and verification of FOREWARNS, a novel method for regional-scale forecasting of surface water flooding. We detail outcomes from a workshop held with UK forecast users, who indicated they valued the forecasts and would use them to complement national guidance. We use results of objective forecast tests against flood observations over northern England to show that this confidence is justified and that FOREWARNS meets the needs of UK flood responders.

Runoff and erosion increase after fire, leading to a greater likelihood of floods and debris flows. We monitored debris flow activity following a fire in western New Mexico, USA, and observed 16 debris flows over a <2-year monitoring period. Rainstorms with recurrence intervals of approximately 1 year were sufficient to initiate debris flows. All debris flows initiated during the first several months following the fire, indicating a rapid decrease in debris flow susceptibility over time.

Scoring and ranking probabilistic seismic hazard models: an application based on macroseismic intensity data

Nat. Hazards Earth Syst. Sci., 24, 1401–1413, https://doi.org/10.5194/nhess-24-1401-2024, 2024
We propose a scoring strategy to rank multiple models/branches of a probabilistic seismic hazard analysis (PSHA) model that could be useful to consider specific requests from stakeholders responsible for seismic risk reduction actions. In fact, applications of PSHA often require sampling a few hazard curves from the model. The procedure is introduced through an application aimed to score and rank the branches of a recent Italian PSHA model according to their fit with macroseismic intensity data.

Quakes do not kill people, bad buildings do

Phys.org: Earth science - Wed, 04/24/2024 - 18:23
Early on Tuesday (April 23), Taiwan was hit by a series of earthquakes with the highest magnitude at 6.3. The latest tremor came less than three weeks after a magnitude 7.4 quake hit the island, damaging more than 100 buildings and trapping dozens of people in collapsed tunnels.

Scientists demonstrate high-resolution lidar sees birth zone of cloud droplets, a first-ever remote observation

Phys.org: Earth science - Wed, 04/24/2024 - 16:45
A team led by atmospheric scientists at the U.S. Department of Energy's Brookhaven National Laboratory has demonstrated the first-ever remote observations of the fine-scale structure at the base of clouds. The results, just published in npj Climate and Atmospheric Science, show that the air-cloud interface is not a perfect boundary but rather is a transition zone where aerosol particles suspended in Earth's atmosphere give rise to the droplets that ultimately form clouds.

Climate change supercharged a heat dome, intensifying 2021 fire season, study finds

Phys.org: Earth science - Wed, 04/24/2024 - 15:29
As a massive heat dome lingered over the Pacific Northwest three years ago, swaths of North America simmered—and then burned. Wildfires charred more than 18.5 million acres across the continent, with the most land burned in Canada and California.

Airborne observations of Asian monsoon sees ozone-depleting substances lofting into the stratosphere

Powerful monsoon winds, strengthened by a warming climate, are lofting unexpectedly large quantities of ozone-depleting substances high into the atmosphere over East Asia, new research shows.

Precise modeling of shocks in inertial confinement fusion implosions is critical for obtaining the desired compression in experiments. Shock velocities and postshock conditions are determined by laser-energy deposition, heat conduction, and equations of state. This paper describes experiments at the…
