What USGS has published since this earthquake
How far the shaking reached
- Light shaking (intensity IV) or more reached about 10 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.
