Puerto Rico tsunami deposit could have come from pre-Columbian megathrust earthquake
Tsunami deposits identified in a coastal mangrove pond in Northwest Puerto Rico could have come from a megathrust earthquake at the Puerto Rico Trench that occurred between 1470 and 1530, according to research reported at the Seismological Society of.....»»
"Bouncing" comets could deliver building blocks for life to exoplanets
How did the molecular building blocks for life end up on Earth? One long-standing theory is that they could have been delivered by comets. Now, researchers from the University of Cambridge have shown how comets could deposit similar building blocks t.....»»
Learning about seismic signatures when the Earth moves: Earthquake risk in Indonesia
Professor Nick Rawlinson is fascinated by the shifting crust of the planet, the jostle of tectonic plates, the rupture of faults and the shaking of the earth......»»
Early career Latinas in STEM continue to face challenges in academia
In 2022, Latinos, as a group, comprised more than 19% of the U.S. population or nearly 64 million individuals. People of Mexican ancestry make up almost 12% of the US population and 62.3% of Latinos. Mexican, Puerto Rican, and Central American Ancest.....»»
Global warming–induced sea level changes could increase earthquake risk
Earthquakes often occur along plate boundaries, when sudden movements of the "stuck" plates release elastic strain energy, sending out seismic waves that result in the ground shaking familiar to many worldwide. More rarely, earthquakes occur within p.....»»
New date evidence for landslides reveals 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......»»
Earthquake rattles Greek island near Athens, but no injuries or serious damage reported
A magnitude 5.1 earthquake rattled an island near Athens early Friday, but local officials had no immediate reports of injuries or serious damage......»»
What caused the volcanic tsunami that devastated a Greek island 373 years ago?

Mystery of volcanic tsunami solved after 373 years
The explosion of the underwater volcano Kolumbo in the Aegean Sea in 1650 triggered a destructive tsunami that was described by historical eye witnesses. A group of researchers led by Dr. Jens Karstens from the GEOMAR Helmholtz Centre for Ocean Resea.....»»
Churches could be key for quake survival, expert says
Text messages began to circulate about five minutes after an earthquake warning sounded for celebrants at St. James' Episcopal Church in South Pasadena on Sunday morning......»»
Earthquake country residents set to "drop, cover and hold on" in annual ShakeOut quake drill
People will duck under desks and tables in California and around the world on Thursday for an annual drill practicing ways to stay safe during earthquakes......»»
How animal traits have shaped the journey of species across the globe
The devastating tsunami that hit Japan in March 2011 set off a series of events which have long fascinated scientists like me. It was so powerful that it caused 5 million tons of debris to wash into the Pacific—1.5 million tons remained afloat and.....»»
New dating of cave art reveals history of Puerto Rican people
In the karstic caves of Puerto Rico, cave art paints the rock walls. Previous research has assigned ages to this art based on the ages of nearby archaeological artifacts within the caves, but these ages are relative and may not reflect the true timin.....»»
Researchers test seafloor fiber optic cable as an earthquake early warning system
One of the biggest challenges for earthquake early warning systems (EEW) is the lack of seismic stations located offshore of heavily populated coastlines, where some of the world's most seismically active regions are located......»»
This AI algorithm could save lives in quake zones
In trials that took place over a seven-month period, the algorithm predicted with impressive accuracy an earthquake's timing, location, and intensity......»»
Researchers find pre-Columbian agave plants persisting in Arizona landscapes
A new paper in the Annals of Botany reveals that researchers have found unaltered agave plant species cultivated by several early cultures including the Hohokam people, a large Native American group in the Southwest that existed between 300 and 1500.....»»
Amazon rain forest hides thousands of records of ancient Indigenous communities under its canopy, says new study
The world's most diverse forest, the Amazon, may also host more than 10,000 records of pre-Columbian earthworks (constructed prior to the arrival of Europeans), according to a new study. The new study combines cutting-edge remote sensing technology w.....»»
AI-driven earthquake forecasting shows promise in trials
A new attempt to predict earthquakes with the aid of artificial intelligence has raised hopes that the technology could one day be used to limit earthquakes' impact on lives and economies. Developed by researchers at The University of Texas at Austin.....»»
Japan lifts a tsunami advisory issued after an earthquake hit near its outlying islands
Japan issued a tsunami advisory Thursday after a strong earthquake struck near its outlying islands in the Pacific Ocean, but lifted it about two hours later. No damage was reported......»»
A double earthquake threat? Study finds 2 Seattle-area faults ripped about the same time
With the Cascadia Subduction Zone parked off the coast and shallow faults lurking under most major cities, the Puget Sound area already faces a daunting array of seismic scenarios. A new study adds another: the possibility of a one-two earthquake pun.....»»
Tree rings reveal a new kind of earthquake threat to the Pacific Northwest
In February, a 7.8-magnitude earthquake shook the Turkey-Syria border, followed by one nearly as large nine hours later. Shallow faults less than 18 miles beneath the surface buckled and ruptured, causing violent focused quakes that leveled thousands.....»»
