A 6.9 magnitude quake that struck off the Southern part of the Philippines on Saturday, December 29, prompted the Pacific Tsunami Warning Center (PTWC) to issue Tsunami alert in nearby countries such as Palau and Indonesia but this was soon lifted after no sign of waves were observed from sea-level data from gauges.

A few residents in Palau reported to have felt the slight tremors around Saturday noon.

PTFC previously forecasted that the waves were less than 0.3 meters above the tide level for the coasts of Indonesia, Palau, and the Philippines.

The U.S. Geological Survey (USGS) reported that the magnitude of the Philippine quake was 7.2 but had later downgraded to 6.9.

 Two serious Tsunamis previously hit Indonesia this year, the first of which was in September that was triggered by a 7.5 magnitude quake on the west coast of Sulawesi island. Over 2,000 people were reportedly killed in the incident. The second Tsunami was triggered by the eruption of Indonesia’s Anak Krakatau volcano with reported casualties of more than 400 people.

The Pacific Ocean is known for its Ring of Fire, a major area in its basin where over 400 volcanoes are located.
