Tuesday, June 18, 2024
12:00-01:00 PM Pacific Time 

QQB NY EarthquakeThe EERI Northern California Regional Chapter is hosting a FREE webinar on the recent earthquake that affected the northeast United States. The earthquake struck mid-morning near Whitehouse Station, New Jersey, and was felt by over 40 million people all across the northeastern United States from Maine in the north to Washington, D.C. in the south. USGS classified the shaking as light (MMI < IV) throughout the region. The following link is to a New York City evening news summary. The New Jersey event was an intraplate earthquake, unlike those that occur in California that are near a plate boundary.  While this earthquake was relatively small, quakes of this magnitude are widely felt in the eastern United States because of the seismic wave propagation characteristics in the region.  Although New York City did not suffer significant damage (40 miles east of epicenter), the city emergency response systems were activated.


  • Oliver Boyd, Ph.D., Research Geophysicist, U.S. Geological Survey.  He will present on the earthquake mechanism and the seismology of the east coast region.

  • Yegal Shamash, PE, Chief Structural Engineer, NYC Department of Buildings.  He will present on the earthquake damage and emergency response actions.
