Sensing shakes
Every year earthquakes worldwide claim hundreds or even thousands of lives. Forewarning allows people to head for safety and a matter of seconds could spell the difference between life and death. UTokyo researchers demonstrate a new earthquake detection method -- their technique exploits subtle telltale gravitational signals traveling ahead of the tremors. Future research could boost early warning systems. (2019-03-10)

Earthquake symmetry
A recent study investigated around 100,000 localized seismic events to search for patterns in the data. University of Tokyo Professor Satoshi Ide discovered that earthquakes of differing magnitudes have more in common than was previously thought. This suggests development of early warning systems may be more difficult than hoped. But conversely, similarities between some events indicate that predictable characteristics may aid researchers attempting to forecast seismic events. (2019-09-04)

Unearthing explanations for New Madrid earthquakes
On Dec. 16, 1811, residents of New Madrid, Mo., were wrested from sleep by violent shaking and a deafening roar. It was the first of three massive earthquakes that rocked the central United States between December 1811 and February 1812, even changing the course of the Mississippi River in their aftermath. At the 2006 meeting of AAAS, Professor Mark Zoback discussed what is known about the New Madrid seismic zone and presented geodynamic models of the region. (2006-02-20)

Newly discovered active fault building new Dalmatian Islands off Croatian coast
A newly identified fault that runs under the Adriatic Sea is actively building more of the famously beautiful Dalmatian Islands and Dinaride Mountains of Croatia, according to a new research report. Geologists had previously believed that the Dalmatian Islands and the Dinaride Mountains had stopped growing 20 to 30 million years ago. The Croatian coast is an increasing popular tourist destination. Dubrovnik, known as (2008-01-22)

Double dose of bad earthquake news
A team of researchers, including one from the University of California, Riverside, has discovered that earthquake ruptures can jump much further than previously thought, a finding that could have severe implications on the Los Angeles area and other regions in the world. (2016-02-08)

Mexico's 2017 earthquake emerged from a growing risk zone
Under Mexico, where the Cocos Plate from the Pacific Ocean slides under the North American Plate, a bending line of hills, created when the seafloor first formed, sits atop a flattened area of subduction. That newly recognized combination, scientists report, has created a fault that likely explains last September's Puebla earthquake, scientists report. (2018-03-12)

Scientists identified earthquake faults in Sichuan, China
Only last summer research published by earth scientists in the international journal Tectonics concluded that geological faults in the Sichuan Basin, China, (2008-05-16)

Seafloor sediments appear to enhance Earthquake and Tsunami danger in Pacific Northwest
The Cascadia Subduction Zone off the coast of the Pacific Northwest has all the ingredients for making powerful earthquakes -- and according to the geological record, the region is due for its next 'big one.' A new study led by The University of Texas at Austin has found that the occurrence of these big, destructive quakes and associated devastating tsunamis may be linked to compact sediments along large portions of the subduction zone. (2017-11-20)

Stalagmites may predict next Big One along the New Madrid Seismic Zone
Small white stalagmites lining caves in the Midwest may help scientists chronicle the history of the New Madrid Seismic Zone -- and even predict when the next big earthquake may strike, say researchers at the Illinois State Geological Survey and the University of Illinois at Urbana-Champaign. Preliminary results of the study will be presented Sun., Oct. 5, at the 2008 Joint Meeting of GSA-SSSA/ASA/CSSA-GCAS in Houston, Texas. (2008-09-25)

Shakedown in Oklahoma: To cut the number of bigger earthquakes, inject less saltwater
In Oklahoma, reducing the amount of saltwater (highly brackish water produced during oil and gas recovery) pumped into the ground seems to be decreasing the number of small fluid-triggered earthquakes. But a new study shows why it wasn't enough to ease bigger earthquakes. The study, led by Ryan M. Pollyea of Virginia Tech in Blacksburg, Va., was published online ahead of print in Geology this week. (2018-01-04)

Distant earthquakes can cause underwater landslides
New research finds large earthquakes can trigger underwater landslides thousands of miles away, weeks or months after the quake occurs. (2017-06-27)

Fatal mine collapse covered 50 acres
New calculations show that the deadly Crandall Canyon mine collapse -- which registered as a magnitude-3.9 earthquake -- began near where miners were excavating coal and quickly grew to a 50-acre cave-in, University of Utah seismologists say in a report on the tragedy. The University of Utah Seismograph Stations estimated the size of the collapse is about four times larger than was thought shortly after the time of the Aug. 6, 2007, disaster. (2008-06-01)

In California, large-scale water cycles impact quakes a little
In California, seasonal changes in large-scale water cycles modestly influence small-scale quake activity, a new study reports. (2017-06-15)

China quake rare and unexpected, says new MIT study
A new analysis of the setting for last month's devastating earthquake in China by a team of geoscientists at MIT shows that the quake resulted from faults with little seismic activity, and that similar events in that area occur only once in every 2,000 to 10,000 years, on average. (2008-06-30)

Discovery of hidden earthquake presents challenge to earthquake early-warning systems
Seismologists at the University of Liverpool studying the 2011 Chile earthquake have discovered a previously undetected earthquake which took place seconds after the initial rupture. This newly discovered phenomena which they called a `closely-spaced doublet' presents a challenge to earthquake and tsunami early warning systems as it increases the risk of larger-than-expected tsunamis in the aftermath of a typical subduction earthquake. (2015-11-16)

The maximum earthquake magnitude for North Turkey
The Istanbul metropolitan region faces a high probability for a large earthquake in the near future. The question is: how large can such an earthquake be? (2016-03-03)

Better understanding post-earthquake fault movement
Preparation and good timing enabled Gareth Funning and a team of researchers to collect a unique data set following the 2014 South Napa earthquake that showed different parts of the fault, sometimes only a few kilometers apart, moved at different speeds and at different times. (2016-07-18)

Health staff 'too stressed' to deal with disasters
Increasing stress and a lack of motivation among healthcare staff could result in hospitals having to shut down in the wake of a major incident such as flooding or an earthquake, according to new research published in the journal Procedia Engineering. (2018-02-26)

Radar reveals details of mountain collapse after North Korea's most recent nuclear test
North Korea's Sept. 3, 2017, underground nuclear test -- it's latest and biggest -- created a 5.2 magnitude earthquake and 4.5 magnitude aftershock. Researchers from Singapore, UC Berkeley, Germany and China combined synthetic aperture radar with seismic measurements to determine that the explosion pushed the mountain surface outward up to 11 feet and left it 20 inches shorter, probably after cavity collapse and subsequent compression of fractured rock. The aftershock may have been a tunnel collapse. (2018-05-10)

The losses that come after the earthquake: Devastating and costly
The study, titled, 'Losses Associated with Secondary Effects in Earthquakes,' published by Frontiers in Built Environmen, looks at the devastation resulting from secondary disasters, such as tsunamis, liquefaction of sediments, fires, landslides, and flooding that occurred during 100 key earthquakes that occurred from 1900 to the present. And unlike previous studies, Daniell et al put a dollar value to the devastation from these secondary causes. (2017-08-25)

Earthquake rupture halted by seamounts
Experts expected for some time that one of the next mega earthquakes occurs off northern Chile. But when the earth did tremble around the northern Chilean city of Iquique in 2014, the strength and areal extent of shaking was much smaller than anticipated. Geologists from the GEOMAR Helmholtz Centre for Ocean Research Kiel, the Institute of Marine Sciences in Barcelona (Spain), and the German Institute for Geosciences and Natural Resources now publish a possible explanation in the international journal Nature Communications. (2015-09-30)

Big quakes spark jolts worldwide
Until 1992, when California's magnitude-7.3 Landers earthquake set off small jolts as far away as Yellowstone National Park, scientists did not believe large earthquakes sparked smaller tremors at distant locations. Now, a definitive study shows large earthquakes routinely trigger smaller jolts worldwide, including on the opposite side of the planet and in areas not prone to quakes. (2008-05-25)

New research reveals hidden earthquake trouble spots
University of Leicester develops technique to reveal earthquake-prone faults in forested mountainous regions. (2006-11-08)

Forecasting large earthquakes along the Wasatch Front, Utah
There is a 43 percent probability that the Wasatch Front region in Utah will experience at least one magnitude 6.75 or greater earthquake, and a 57 percent probability of at least one magnitude 6.0 earthquake, in the next 50 years, say researchers speaking at the 2017 Seismological Society of America's (SSA) Annual Meeting. (2017-04-13)

Landslide modeling after Kaikoura Quake provides data to first responders
Hours after the 2016 Kaikoura earthquake hit New Zealand, researchers were able to share information with first responders about where significant landsliding might have occurred to block roads and rivers, according to a new report in the Bulletin of the Seismological Society of America. (2018-03-26)

Release of water shakes Pacific Plate at depth
A team of seismologists analyzing the data from 671 earthquakes that occurred between 30 and 280 miles beneath the Earth's surface in the Pacific Plate as it descended into the Tonga Trench were surprised to find a zone of intense earthquake activity in the downgoing slab. The pattern of the activity along the slab provided strong evidence that the earthquakes are sparked by the release of water at depth. (2017-01-11)

Chinese earthquake provides lessons for future
The May 12 Sichuan earthquake in China was unexpectedly large. Analysis of the area, however, now shows that topographic characteristics of the highly mountainous area identified the mountain range as active and could have pointed to the earthquake hazard. Topographic analysis can help evaluate other, similar fault areas for seismic risk, according to geologists from Penn State and Arizona State University. (2008-07-21)

Major flooding risk could span decades after Chinese earthquake
Up to 20 million people, thousands of whom are already displaced from their homes following the devastating Chinese earthquake, are at increased risk from flooding and major power shortages in the massive Sichuan Basin over the next few decades and possibly centuries. Dr. Alex Densmore, a geographer from Durham University, makes the observations on returning from carrying out investigative fieldwork in the China earthquake zone. (2008-09-04)

Determinant factors for energy consumption and perception of energy conservation clarified
Change in lifestyle is a key component to realizing a low-carbon society. A research group at Osaka University examined determinant factors associated with the residential consumption and perception of savings of electricity and gas based on data collected from a large-scale survey in Suita City, Osaka, Japan, in two different years: 2009 and 2013, and 'household income,' 'actual amount of energy consumption,' and 'perception of energy savings' were identified as three closely related elements. (2015-12-02)

Earthquake aftermath: Life-threatening blood clots in legs and lungs from sitting in cars for extended periods
Japanese physicians highlight the risks and clinical significance for individuals who remain seated and immobile in vehicles for prolonged periods. They call for preventive awareness activities and education about the risk of venous thromboembolisms (VTE) in a Letter to the Editor in the Canadian Journal of Cardiology. (2018-05-03)

Oklahoma's earthquakes strongly linked to wastewater injection depth
Man-made earthquakes in Oklahoma, USA, are strongly linked to the depth at which wastewater from the oil and gas industry are injected into the ground, according to a new study led by the University of Bristol. (2018-02-01)

Seismologists introduce new measure of earthquake ruptures
A team of seismologists has developed a new measurement of seismic energy release that can be applied to large earthquakes. Called the Radiated Energy Enhancement Factor (REEF), it provides a measure of earthquake rupture complexity that better captures variations in the amount and duration of slip along the fault for events that may have similar magnitudes. (2018-03-21)

Earthquake in Illinois could portend an emerging threat
To the surprise of many, the earthquake on April 18, 2008, about 120 miles east of St. Louis, originated in the Wabash Valley Fault, not the better-known and more-dreaded New Madrid Fault in Missouri's bootheel. The concern of Douglas Wiens, Ph.D., and Michael Wysession, Ph.D., seismologists at Washington University in St. Louis, is that the New Madrid Fault may have seen its day and the Wabash Fault is the new kid on the block. (2008-04-24)

New model could help predict major earthquakes
Nagoya University-led researchers characterized several earthquakes that struck South America's west coast over the last 100 years by using seismographic data, tsunami recordings, and models of the rapid plate movements associated with these natural disasters. The team showed that some earthquakes were linked to the same sites of rupture at plate boundaries and others to different sites. Thus, they revealed the periodicity and intensity of earthquakes associated with particular sites, potentially aiding future earthquake prediction. (2017-04-26)

To a fault: the bottom line on earthquakes
Although many people think that California (2008-04-22)

Dissection of the 2015 Bonin deep earthquake
