Following the M4.1 Delaware earthquake that occurred on November 30, 2017 I was part of a team of scientists from five institutions (Carnegie, University of Maryland, Lamont, USGS, and Lehigh University) that deployed seismometers close to the epicenter in Delaware and New Jersey to monitor for aftershocks following the event. These will be important for understanding why this relatively rare east coast earthquake occurred. Within 24 hours of the earthquake, we deployed 18 new instruments. The instruments will remain in the ground for several weeks. Local media covered the deployment of these instruments, and I gave a brief interview to explain what we were doing; these can be found here.
