What USGS has published since this earthquake

Shaking and its likely impact

USGS estimates about 1.2 million people were exposed to very strong shaking or worse (intensity VII and above), and about 630,000 more to strong shaking (intensity VI).

USGS's PAGER system gives an orange alert for deaths, with 100 to 1,000 the most likely range; and a red alert for economic losses, with $10 billion to $100 billion the most likely range. 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 102 "Did You Feel It?" reports; the strongest shaking reported was intensity IX (violent).

How far the shaking reached

• Severe shaking (intensity VIII) or more reached about 25 km from the epicentre at its farthest.
• Very strong shaking (intensity VII) or more reached about 35 km from the epicentre at its farthest.
• Strong shaking (intensity VI) or more reached about 75 km from the epicentre at its farthest.
• Moderate shaking (intensity V) or more reached about 110 km from the epicentre at its farthest.
• Light shaking (intensity IV) or more reached about 170 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.
