4-6-24 SHORT HILLS: I forgot to mention our earthquake yesterday. It lasted about ten seconds. I was walking upstairs, and the second floor of the house was moving much more than the first. After it settled down, I walked around an found that nothing had so much as fallen off a shelf. At first we weren’t sure that if was an earthquake and not just a heavy truck rumbling by.
An earthquake was confirmed by news media and the local PD. The epicenter was in Whitehouse Station, NJ—magnitude 4.8, 2.9 miles below the surface, 23 miles west of us at 10:23 AM.
The epicenter of the quake in red and our house in blue.
The Ramapo Fault system runs near the epicenter, although that fault system has not been well-connected to earthquakes that have occurred near by. The quake was felt from Baltimore to Boston. An aftershock early this morning at 6 AM was of 2.5 magnitude, but we didn’t feel it. Dozens of minor aftershocks of magnitude 1-2 have occurred. Yesterday evening a larger aftershock, magnitude 3-4, occurred at about 6 PM. Wikipedia has excellent discussions of the Geology of this area.
Otherwise we had a visit from Lily and Danna this morning after they dropped Danna’s family at Newark Airport. Yesterday we had dinner with Alan. And tomorrow we have brunch in NYC with Richard and Elaine.
