A preliminary data set of 234 aftershocks recorded on the temporary array has been analysed. We expect the complete dataset to contain more than 1,000 aftershocks. The epicenter of the mainshock is indicated by the star. Preliminary epicenters of some aftershocks are shown with open circles.
Population centers are squares.
There are 234 events shown on the map. Most earthquakes on the map are likely less than magnitude 3. This figure shows hypocenters using a vertical, north-south crossection. Elevation on the left is in kilometers and distance along the bottom is in degrees latitude. Date and record start times are on the left.
