What USGS has published since this earthquake

Shaking and its likely impact

USGS estimates about 2,800 people were exposed to very strong shaking or worse (intensity VII and above), and about 23,000 more to strong shaking (intensity VI).

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.

How far the shaking reached

  • Strong shaking (intensity VI) or more reached about 5 km from the epicentre at its farthest.
  • Moderate shaking (intensity V) or more reached about 20 km from the epicentre at its farthest.
  • Light shaking (intensity IV) or more reached about 50 km from the epicentre at its farthest.

USGS ShakeMap, automatic: an estimate built from seismic stations, felt reports and a model where there are neither. Distances are in a straight line from USGS's epicentre; the lines on the map above are USGS's contours, simplified. Shaking varies with the ground, so a place inside a line may have felt less or more.
