The History of Lake Cahuilla Before the Salton Sea
Today, the Salton Sea is an eerie place. Its mirror-like surface belies the toxic stew within. Fish skeletons line its shores and the ruins of a once thriving vacation playground is a reminder of better days.
New earthquake assessments available to strengthen preparedness in Europe
During the 20th century, earthquakes in Europe accounted for more than 200,000 deaths and over 250 billion Euros in losses.
Explaining the slow surprise in the middle of the sandwich (earthquake)
The 12 August 2021 South Sandwich Island earthquake had a surprise hidden within its complex rupture sequence: a slow, shallow magnitude 8.16 subevent that was “invisible” to researchers at first glance.
Scientists anticipated Alaska quake, but when and where proved elusive
An 8.2-magnitude earthquake struck off the southern coast of Alaska on Wednesday night — the largest in the U.S. in decades. It caused shaking and tsunami warnings, forcing communities to seek shelter. Geoff Abers is chair of earth and atmospheric…
U scientists plumb the depths of the world’s tallest geyser
U scientists were ready to jump at the opportunity to get an unprecedented look at the workings of Steamboat Geyser. Their findings provide a picture of the depth of the geyser as well as a redefinition of a long-assumed relationship between the geyser and a nearby spring.
Catching energy-exploration caused earthquakes before they happen
Geoscientists at Sandia National Laboratories used 3D-printed rocks and an advanced, large-scale computer model of past earthquakes to understand and prevent earthquakes triggered by energy exploration.
Unusual earthquakes highlight central Utah volcanoes
Earthquakes in the Black Rock Desert are rare and capturing the seismic recordings from these earthquakes provides a glimpse into the volcanic system of the Black Rock Desert that, while not showing any signs of erupting, is still active.
Most landslides in western Oregon triggered by heavy rainfall, not big earthquakes
Deep-seated landslides in the central Oregon Coast Range are triggered mostly by rainfall, not by large offshore earthquakes.
Highest ever resolution earthquake simulations on Sierra supercomputer
A Lawrence Livermore National Laboratory (LLNL) team has published new supercomputer simulations of a magnitude 7.0 earthquake on the Hayward Fault. This work represents the highest ever resolution ground motion simulations from such an event on this scale.
Researchers catch a wave to determine how forces control granular material properties
Stress wave propagation through granular material is important for detecting the magnitude of earthquakes, locating oil and gas reservoirs, designing acoustic insulation and designing materials for compacting powders. A team of researchers including Lawrence Livermore National Laboratory (LLNL) physicist Eric Herbold used X-ray measurements and analyses to show that velocity scaling and dispersion in wave transmission is based on grainy particle arrangements and chains of force between them, while reduction of wave intensity is caused mainly from grainy particle arrangements alone.
Looking Up to the Stars Can Reveal What’s Deep Below
Using a new technique originally designed to explore the cosmos, scientists have unveiled structures deep inside the Earth, paving the way towards a new map revealing what Earth’s interior looks like.
Six Berkeley Lab Scientists Named AAAS Fellows
Six scientists from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have been named Fellows of the American Association for the Advancement of Science (AAAS).
