A strong earthquake registered by the USGS as M6.1 (downgraded from M6.3) hit near the east coast of Kyushu, Japan at 23:48 UTC on May 8. The agency is reporting a depth of 23 km (14.3 miles).
The epicenter was located 43 km (26.7 miles) ESE of Miyazaki-shi (population 311,203), Japan.
A smaller M5.6 quake preceded the larger M6.1 at 22:43 UTC, and within the space of 5 hours two powerful aftershocks were registered — a M5.1 and a M4.6.
More than 1.3 million are estimated to have felt shaking.
No tsunami warnings have been issued, and the quakes are unlikely to have caused any damage.
Seismic and Volcanic activity has been correlated to changes in our sun.
The recent global uptick in earthquakes and volcanic eruptions is likely attributed to the drop-off in solar activity, coronal holes, a waning magnetosphere, and the increase in Galactic Cosmic Rays penetrating silica-rich magma.
