A major earthquake of magnitude 7.6 occurred Friday deep beneath the Moro Gulf, Mindanao, Philippines. The earthquake was too deep to cause a tsunami. Additionally, because of the depth, it was reported to be hardly felt, and no damage has been reported. However, this earthquake was the mainshock of an unusual sequence of three earthquakes between magnitude 7.3 and 7.6 that occurred in a cluster about 600 km deep inside the Philippine Plate within an interval of 67 minutes.
