By now you may have heard - or even felt - an overnight earthquake that shook parts of New Jersey.
We spoke with @GeosciencesPU professor Frederik Simons to learn more about it — and how it affected the Princeton area.

"Earthquakes in New Jersey are rare — but they do happen! This morning at 2am most of us in Princeton may have been asleep, but there was enough ground shaking from this local magnitude 3.1 quake at 5 km depth under Freehold, NJ, to wake us up — including my family."
While it took some convincing for Simons to believe it was indeed an earthquake that woke his family up, he goes on to say that "there are some 100,000 magnitude 3 earthquakes per year ... but they do not frequently occur this close to home!" https://bit.ly/35senq2
Yuri Tamama '22 and visiting professor @jess_irving recorded the quake through the seismometer at Guyot Hall.
Did you feel the quake in your part of the state? You can file a "Felt Report" and help the seismological community gather data and continue updating their records and analyses. https://on.doi.gov/2Rgzfs1
