According to the US Geological Survey, a strong earthquake of magnitude 6.8 occurred on the southern coast of Japan on Monday.
According to the agency, the earthquake occurred at 21:19 Japan time, 7 miles southeast of Miyazaki.
As seismologists review available data, they may revise the earthquake's reported magnitude. Additional information gathered about the earthquake may also prompt USGS scientists to update the magnitude map.
Earthquakes in the region
An aftershock is usually a smaller earthquake followed by a larger one in the same general area. Aftershocks are usually small adjustments along the part of the fault that slipped during the initial earthquake.
Earthquakes and aftershocks within 100 miles
Aftershocks can occur days, weeks or even years after the first earthquake. These events can be of the same or greater magnitude as the initial earthquake and may continue to affect areas already damaged.
