A new origin story for deadly Seattle fault
The Seattle fault zone is a network of shallow faults slicing through the lowlands of Puget Sound, threatening to create damaging earthquakes for the more than four million people who live there.
New dates for landslides reveal past Seattle fault earthquakes
New maps of more than 1,000 deep-seated landslides in the Puget Lowlands of Washington State provide evidence of the last major earthquake along the Seattle Fault about 1,100 years ago—and may also hold traces of older earthquakes along the fault.
Scientists Isolate Early-Warning Tremor Pattern in Lab-Made Earthquakes
Researchers at The University of Texas at Austin have successfully isolated a pattern of lab-made ‘foreshock’ tremors. The finding offers hope that future earthquakes could be forecast by the swarm of smaller tremors that come before them.
What can central Utah’s earthquake ‘swarms’ reveal about the West’s seismicity?
U seismologists are analyzing decades of seismic data in the hope of discerning the significance of earthquake swarms in a geologically complex region known as a geothermal hotspot and for recent—geologically speaking—volcanism.
Researchers unearth the mysteries of how Turkey’s East Anatolian fault formed
An international team led by the University of Minnesota Twin Cities has, for the first time, accurately determined the age of the East Anatolian fault, allowing geologists to learn more about its seismic history and tendency to produce earthquakes.
Rise of malicious bots: how automatons shake up Twitter with earthquake conspiracies
In light of the growing dominance of social media and the spread of misinformation, a new paper reveals how bots contribute to the dissemination of conspiracy theories surrounding earthquakes.
Expert Available on Earthquakes and Damage in Turkey and Syria
Rensselaer Polytechnic Institute’s Mourad Zeghal, professor of civil and environmental engineering, is available for comment on the earthquakes in Turkey and Syria. He can speak on ground motion during earthquakes, soil-structure interaction, and damage to buildings and infrastructure. Zeghal’s research…
Earthquake lab experiments produce aftershock-like behavior
Earthquakes are notoriously hard to predict, and so too are the usually less-severe aftershocks that often follow a major seismic event.
Double trouble when 2 disasters strike electrical transmission infrastructure
One natural disaster can knock out electric service to millions. A new study suggests that back-to-back disasters could cause catastrophic damage, but the research also identifies new ways to monitor and maintain power grids.
KyotoU PEGS away at catching quakes at light speed
A novel AI-based approach to detect earthquakes early uses prompt elasto-gravity signals, or PEGS, gravitational changes generated by large-mass motion in megaquakes. PEGS carry information about an ongoing earthquake at the speed of light, arriving much faster than even the fastest seismic waves.
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.
Volcanoes at fault if the Earth slips
The 2016 Kumamoto earthquakes shocked inhabitants of the western island of Kyushu, causing hundreds of casualties and serious damage to vital infrastructure.
Pictograms are first written accounts of earthquakes in pre-Hispanic Mexico
The Codex Telleriano Remensis, created in the 16th century in Mexico, depicts earthquakes in pictograms that are the first written evidence of earthquakes in the Americas in pre-Hispanic times, according to a pair of researchers who have systematically studied the country’s historical earthquakes.
Earthquake Threat! Understanding the Intention to Prepare for the Big One
How do people in high-risk regions for natural disasters, perceive risks and what influences their intentions to prepare? A new study, soon to be published in the journal Risk Analysis, investigates whether residents of higher-risk earthquake areas within the region…
World’s largest outdoor earthquake simulator undergoes major upgrade
A major upgrade to the world’s largest outdoor earthquake simulator reached a milestone mid-April when the facility’s floor–all 300,000 lbs of it–was put back into place. When completed this fall, the simulator will have the ability to reproduce multi-dimensional earthquake motions with unprecedented accuracy to make structures and their residents safer during strong shakes. Researchers lay out the details of the upgrade in a paper published recently in Frontiers in Built Environment.
UC San Diego engineering professor solves deep earthquake mystery
A University of California San Diego engineering professor has solved one of the biggest mysteries in geophysics: What causes deep-focus earthquakes?
These mysterious earthquakes originate between 400 and 700 kilometers below the surface of the Earth and have been recorded with magnitudes up to 8.3 on the Richter scale.
It Comes in Waves
Tsunamis pose a real threat to the California coast, even if the triggering earthquakes occur elsewhere. CSU researchers are helping ensure coastal cities are ready.
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.
AI reveals first direct observation of rupture propagation during slow quakes
Using a trained neural network and data from the North Anatolian Fault in Turkey, a research team led by Los Alamos National Laboratory revealed the first direct observation of rupture propagation during a slow earthquake.
New connection method makes precast building repair fast, cost-effective
A newly patented method of connecting precast beams and columns will make it possible to quickly repair concrete buildings damaged by earthquakes and hurricanes.
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.
Computer Vision Technology Helps Analyze Michigan Dam Collapse
New Brunswick, N.J. (June 26, 2020) – Rutgers engineers have created a 3D model of last month’s devastating break in the Edenville Dam in Michigan, using the emerging technology of computer vision to analyze a smartphone video posted on social…
Rutgers Geology Museum Hosts Open House
Presentations on natural disasters such as earthquakes, volcanoes and their impacts will be held in Scott Hall and are open to the public at the Rutgers Geology Museum’s 52nd Annual Open House. There will also be hands-on activity sessions for kids, a mineral sale and rock and mineral identification in Scott Hall, and make-and-take stations in the Rutgers Geology Museum. Field Station Dinosaurs will bring its baby Hadrosaurus puppet and will also offer hands-on activities for visitors. All events are free and no preregistration is required.
Puerto Rico earthquakes: Evacuations, health safety and compounding effects of multiple disasters
The University of Delaware’s Disaster Research Center has several sources who can contribute to articles about the earthquakes in Puerto Rico and offer valuable information for both during and after the disaster. – Jennifer Horney, a professor of epidemiology, can talk about…
