Tokyo (CNN)A 7.0-magnitude earthquake struck early Saturday morning in Japan's Kyushu island, the same region a magnitude-6.2 quake struck two days earlier.

The U.S. Geological Survey reported that the latest quake struck just west-southwest of Kumamoto-shi and about 8 miles south-southeast of Ueki -- the epicenter of the late-Thursday tremor that left nine dead.
It was not immediately clear if anyone was injured or killed as a result of Saturday morning's seismic event. Nor was it clear how much damage, if any, had been caused.
But it did prompt the Japan Meteorological Agency to issue a tsunami advisory for coastal regions of Japan on the Ariake Sea and Yatsushiro Sea around 2 a.m. Saturday (1 p.m. ET Friday). The agency subsequently lifted all tsunami warnings and advisories.
Tsunami advisories are issued when the tsunami height is expected to between 0.2 and 1 meter (0.65 to 3.3 feet). A warning would be for larger tsunamis.
