A powerful earthquake registered by the USGS as M6.4 hit near Tutubigan, Philippines at 05:37 UTC (13:37 LT) on April 23. The agency is reporting a depth of 54 km (33.5 miles).
This earthquake is the second M6.0+ to hit the country in less than 24hours — the first being the deadly M6.1 on April 22 that killed at least 11 people.
The epicenter was located 13km (8 miles) E of Tutubigan, Philippines.
There are almost 3 million people living within 100 km (62 miles).
Some 6.5 million are estimated to have felt the shaking.
PHIVOLCS said casualties, damage and aftershocks are expected.
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.
