World Series of Earthquakes

IRIS's World Series addresses regional tectonic forces and resulting recent and historic earthquakes around the world (ex. Japan, Alaska, Peru-Chile, Central America, Mexico, Pacific Northwest). Continue Reading

IRIS Statement on Racism in Geoscience

We at IRIS join our colleagues from across the country and around the globe in unequivocally denouncing racism. BLACK LIVES MATTER. We also know that racism is persistent in STEM and that there are systemic inequalities in academia and particularly in the geosciences. Continue Reading

Reduction in seismic noise because of changes in human activity

Researchers who study Earth’s movement are seeing a drop in seismic noise as a result of transport networks and other human activities being shut down. Continue Reading
