Deep-sea observatories to offer new view of seabed earthquakes

A mission to study New Zealand's largest fault by lowering two sub-seafloor observatories into the Hikurangi subduction zone is underway this week. The expedition is...

Researchers discover evidence of earthquakes that affected Chilean coast in the...

A scientific team has discovered the geological footprint of earthquakes and tsunamis that affected the Aysén region (southern Chile) up to 9,000 years ago....

Human-made earthquake risk reduced if fracking is 895m from faults

The risk of human-made earthquakes due to fracking is greatly reduced if high-pressure fluid injection used to crack underground rocks is 895m away from...

Earthquakes follow wastewater disposal patterns in southern Kansas

Wastewater created during oil and gas production and disposed of by deep injection into underlying rock layers is the probable cause for a surge...

Analysis of major earthquakes supports stress reduction assumptions

A comprehensive analysis of 101 major earthquakes around the Pacific ring of fire between 1990 and 2016 shows that most of the aftershock activity...

Hayward fault earthquake simulations increase fidelity of ground motions

Human-made earthquakes in Oklahoma, USA, are strongly linked to the depth at which wastewater from the oil and gas industry are injected into the...

Giant earthquakes: Not as random as thought

By analyzing sediment cores from Chilean lakes, an international team of scientists discovered that giant earthquakes reoccur with relatively regular intervals. When also taking...

Do moon phases produce big earthquakes?

Huge earthquakes are not significantly influenced by the moon, a new study says. The study, conducted by U.S. Geological Survey seismologist Susan Hough, looked at...

Fox Creek earthquakes linked to completion volume and location of hydraulic...
