This just today from CNN:
A series of four strong earthquakes spanning just over an hour struck the Philippines' Moro Gulf on Saturday morning, according to the U.S. Geological Survey.
Three of the four earthquakes had magnitudes between 7.3 and 7.6; the other came in at a 5.4 magnitude. The first quake struck at 6:08 a.m. (6:08 p.m. ET Friday) and the fourth hit at 7:15 a.m. The last quake ran the deepest at 616 (382 miles) kilometers.
The epicenters of the quakes were about 100 kilometers (62 miles) off the coastal city of Cotabato.
No tsunami warning was immediately issued for any of the quakes.
There were no reports of damage, said Rona Faeldin of the Philippines Coast Guard.
We felt 3 of the 4 quakes here at home. It was pretty impressive - all within the space of about an hour! Lamp shades, doors, telephone wires outside were all swaying. Each quake lasted quite awhile - between 1 1/2 and 2 minutes.
No damage done - just another witness of God's incredible power!
