Science Behind Nevada's 2020 Earthquake
In the early morning of May 15, 2020, a magnitude 6.5 earthquake shook Nevada awake. The largest since 1954! This quake occurred in a fascinating seismically active area called The Walker Lane. Learn about this and the Mina deflection from the geologists at UT Dallas’ GeoScience Studio
– Special thanks to our scientific advisors for this episode –
Dr. Nick Mueller and Dr. Scott Kerstetter for their invaluable information on the Mina deflection and the surrounding area and thanks to Dr.Timothy Dixon and Taha Chorsi for their work with the interferometry figures used in this episode
