US Array – Viewing Seismic Waves from Earthquakes

US Array

We hear the term “seismic waves” and we think of earthquakes.  But have you ever seen a seismic wave?  What does it look like?  Can it be measured?  All of these questions can be addressed by visualizing data from the US Array network –  Watch the video below to learn how US Array works.

Now that you have a brief understanding on seismic waves and the US Array network, let’s take a look at several historical earthquakes measured and visualized on the US Array network:

February 22, 2008 – M6.3 Wells, NV Earthquake

September 29, 2009 – M8.1 Samoa Earthquake

January 12, 2010 – M7.0 Haiti Earthquake

August 23, 2011 – M5.8 Mineral VA Earthquake

While this isn’t earthquake prediction, systems like US Array have been deployed in places like Japan, and when extremely catastrophic earthquakes occur, the network can detect the quake and communicate ahead of the damaging waves that people need to prepare for intense ground shaking.  This type of a network / system could provide valuable seconds needed to “Duck, Cover & Hold On!” – potentially mitigating injuries and the loss of life.
