Campus seismometers illustrate compliance with the stay-at-home order

In recent months, seismometers have seen a sharp decline in the level of background noise as human activity has been curtailed in response to COVID-19. The seismograms recorded in the basement of Guyot Hall reveal the decline in local seismic noise, first after the end of on-campus instruction on March 13, and then a more dramatic decrease after Governor Murphy’s stay-at-home order on March 21.
