国家地震灾害模型，2023 年

纽约市的地震

您知道自己生活在“地震带”吗?这是真 的。纽约市等地过去曾发生过地震，将来 还会发生。如果您感到地面在震动，请确 保知道怎么做:趴下、掩护和稳住!

如果您感觉到地面在震动

趴下 掩护 稳住

TITLE: WHERE EARTHQUAKES OCCUR

MAP: National Seismic Hazard Model, 2023

HEADING: EARTHQUAKES IN NYC

This hazard map is a simplified 2% in 50-year probability of exceedance map for fixed VS30 760 m/s.

Annual number of earthquakes with a magnitude of 3.0 or larger in the central and eastern United States, 1973–2022. The long-term rate of approximately 25 earthquakes per year increased sharply starting around 2009.

EARTHQUAKES: WHAT YOU FEEL

EARTHQUAKE INTENSITY

Map showing distribution of average annualized earthquake loss by region. The high concentration of loss in California and the West Coast is consistent with that region’s high seismic hazard, significant population, and building exposure. 

Although most economic loss is concentrated along the west coast, the distribution of relative earthquake risk, as measured by the Annualized Earthquake Loss Ratio (AELR), is spread throughout the country and it reinforces the fact that earthquakes are a national problem.

The large HTHH volcanic explosion created fast low-frequency pressure waves that penetrated about 3.1 miles/5 kilometers into the shallow crust (shown in yellow). Wind and small explosions (shown in blue) create shorter pressure waves that only penetrate down about 328 feet/100 meters.

The waveforms of the ground motion recording and the pressure sensor recording from a station with both types of instruments (see second image above) match up, indicating that the pressure waves are causing the ground (crust) to deflect.

GSN station IU-KBS is located in Svalbard, a Norwegian archipelago. Tyler Storm packs up for a shipment back home.
