State seismologists allayed fears of a tsunami following a magnitude-7.8 quake that hit Indonesia early Wednesday morning. Philippine Institute of Volcanology and Seismology (Phivolcs) scientist Mylene Enriquez said there was no indication of a tsunami following the quake. “The quake happened at sea but there is no tsunami warning from the Pacific Tsunami Warning Center,” Enriquez said in an interview on dzBB radio. “Usually, a tsunami alert must be issued immediately after the earthquake. If there is a risk for a tsunami, an alert must be issued within about five minutes [after quake],” Enriquez later said in an interview with GMANews.TV “The origin of the earthquake was deep that's why it would not generate a tsunamin. It iw were shallow, like ‘10 kilometers or less, that will generate (a tsunami),” she added. But she said that while there was no initial report of damage to property, aftershocks can still happen.
