What USGS has published since this earthquake

Shaking and its likely impact

USGS estimates fewer than 1,000 people were exposed to strong shaking or worse (intensity VI and above).

USGS's PAGER system gives a green alert for deaths, meaning a low likelihood of casualties; and a green alert for economic losses, meaning a low likelihood of damage. These are estimates from a model of the shaking and the population it reached, not a count.

USGS PAGER, automatic.

Reports of the shaking

USGS received 1 "Did You Feel It?" report; the strongest shaking reported was intensity III (weak).

From the U.S. Geological Survey. The USGS event page has the maps and everything USGS has published for this earthquake.
