Alaska earthquakes offer new insight into improving hazard assessment

The 2016 Iniskin earthquake (magnitude 7.1) that shook Anchorage, Alaska, was captured by the seismometers of the EarthScope Transportable Array. This data is helping...

Oil extraction likely triggered mid-century earthquakes in L.A.

World War II-era oil pumping under Los Angeles likely triggered a rash of mid-sized earthquakes in the 1930s and 1940s, potentially leading seismologists to...

Punctuated earthquakes for New Madrid area: New research uncovers cluster of...

In 1811 and 1812, the region around New Madrid, Missouri, experienced a number of major earthquakes. The final and largest earthquake in this sequence...

White line of algae deaths marks uplift in 2016 Chilean earthquake

A bleached fringe of dead marine algae, strung along the coastlines of two islands off the coast of Chile, offers a unique glimpse at...

Where water goes after fracking is tied to earthquake risk

In addition to producing oil and gas, the energy industry produces a lot of water, about 10 barrels of water per barrel of oil...

Micro-earthquakes preceding a 4.2 earthquake near Istanbul as early warning signs?

One of the high-risk geological structures lies near Istanbul, a megacity of 15 million people. The North Anatolian fault, separating the Eurasian and Anatolian...

Relationship between tremors, water at the Cascadia margin

The earthquakes are so small and deep that someone standing in Seattle would never feel them. In fact, until the early 2000s, nobody knew...

Mexico’s 2017 Tehuantepec quake suggests a new worry

Last September's magnitude 8.2 Tehuantepec earthquake happened deep, rupturing both mantle and crust, on the landward side of major subduction zone in the Pacific...

Quiescent British Columbia fault capable of producing large earthquakes

A Canadian fault scientists thought was inactive may actually be capable of producing large-magnitude earthquakes, a new study finds. The results suggest residents of...

Huge earthquake simulator getting upgrade to better simulate deadly temblors

The University of California, San Diego's outdoor shake table in Scripps Ranch will soon give engineers a truer sense of the fury released when...

Kaikoura earthquake research suggests new approach to earthquake forecasting

New research led by Victoria University of Wellington geophysicist Associate Professor Simon Lamb and published in Nature Geoscience has revealed how understanding the events...

New approach offers high-resolution seismic monitoring of the shallow subsurface

Accurate monitoring of the ground beneath our feet for signs of seismic activity to identify natural phenomena such as earthquakes, volcanic eruptions and the...

Researchers map susceptibility to human-made earthquakes

Earthquakes in Oklahoma and Kansas had been on the rise due to injection of wastewater -- a byproduct of oil and gas operations --...

Seismic analysis identifies 2017 North Korean nuclear explosion, collapse, earthquakes

Careful analysis of data collected after the 3 September 2017 North Korean declared nuclear test explosion has allowed seismologists to distinguish the separate seismic...

Regional seismic data help to locate September 2017 North Korean nuclear...

The epicenter of the 3 September 2017 nuclear test explosion in North Korea occurred about 3.6 kilometers northwest of the country's first nuclear test...

How slick water and black shale in fracking combine to produce...

Radioactivity in fracking wastewater comes from the interaction between a chemical slurry and ancient shale during the hydraulic fracturing process, according to Dartmouth College...
