The Philippines is situated in the so-called "Ring of Fire", a seismically-active horseshoe-shaped zone of volcanoes and fault lines circling the edges of the Pacific Ocean.

The US Geological Survey reported that a 6.3-magnitude earthquake occured one kilometre north-northeast of Gutad, Philippines on Monday, 22 April at 9:11 (UTC).
