This information will be updated as needed. Our data base of earthquake hypocenters contains information from the 19th century to the present. Shallow events are black. Events deeper than 35 km are green. A map showing a closer view of the earthquake and prior historical earthquakes with magnitude 3.5 or greater.
Shallow events are black.
Events deeper than 35 km are green. A list of 10 big earthquakes preceding the mainshock that are closest to it and have a magnitude greater than 3.5. A map showing the location of the earthquake relative to cities. A map showing the location of the earthquake relative to the nearest seismograph stations that recorded it. For the locations of these events see the next map.
