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

New Animations! Geoscience Opportunities

Two new animations explore exciting potential careers for people with geoscience degrees.

NEW ANIMATION! ShakeAlert: Earthquake Early Warning System for the West Coast

This animation demonstrates how ShakeAlert works by showing how P & S waves are used to locate and measure earthquakes, then send notice to your location about arrival times of potentially damaging waves. 

SCIENCE AND PROGRAM HIGHLIGHTS

Seeing seismic swarms

Seeing seismic swarms

 In January of 2014 a small seismic swarm rattled Virginia City for approximately 10 days. Swarm-like activity can cause concern because swarms can evolve over time, resulting in damaging ground motions.
Mozambique experiences damaging rift-related earthquakes

Mozambique experiences damaging rift-related earthquakes

 Central Mozambique has experienced several damaging earthquakes in the last few decades, including a M5.6 event on December 22, 2018, near the Zimbabwe border. Seismic stations from around the world helped to clarify the characteristics of this earthquake.

Researchers Develop New Explanation for Destructive Earthquake Vibrations

Researchers Develop New Explanation for Destructive Earthquake Vibrations

 Brown University researchers propose that rocks colliding inside a fault zone as an earthquake happens are the main generators of high-frequency vibrations.
