For the past 25 years, power production has been accompanied by a small but steady increase in seismicity near geothermal wells. A new project seeks to explore why.
Last August, stations on a newly deployed permanent ocean floor observation network recorded rarely seen, very low frequency signals from shallow earthquakes.
Researchers look at induced seismicity data in Oklahoma to spot an increase of stress in faults that could cause even more damage than recent quakes.
Earthquakes in Idaho's panhandle are usually caused by the Earth's crust pulling apart. So why were earthquakes on 24 April pushing the crust together?
Researchers examined the crustal deformation associated with earthquakes that occurred before the 2011 Tohoku-oki earthquake.
A statistical analysis cannot prove with high confidence that the recent global increase in large (M≥5.6) earthquakes could not have happened by random chance.
