MANADO, NETRALNEWS.COM - Head of Data and Information Section of Winangun Geophysics Station, Manado City, Edward H. Mengko said an earthquake with a magnitude of 6.6 that shook the Mindanao mainland, Philippines, at 08.04.45 Indonesian Western Time, was triggered by a local fault.
"Noting the epicenter location and the depth of the hypocenter, the shallow earthquake was caused by a local fault," Edward quoted BMKG Earthquake and Tsunami Center Head Rahmat Triyono in the release distributed by North Sulawesi BMKG, Tuesday (10/29/2019).
The results of the analysis of the source mechanism show that the earthquake has a sliding mechanism (Strike-Slip) and the impact is felt in Tahuna (Sangihe Islands Regency) and Melonguane (Kepulauan Talaud Regency) II-III MMI (vibrations felt in the house, vibrations felt as if the truck passed ).
Until now, there have been no reports of the impact of damage caused by the quake.
"The results of the modeling show that this earthquake has no tsunami potential," he said.
After the main earthquake, up to 09.40 WIB showed five aftershock activities with the largest magnitude of 5.4.
Edward urged people to remain calm and not be affected by issues that cannot be accounted for.
"The public is expected to avoid buildings that are cracked or damaged by the earthquake. Check and make sure the residential buildings are earthquake-resistant enough, or there is no damage that endangers the stability of the building before returning to the house," he said.
He hopes that the community will also ensure that official information is only sourced from BMKG which is distributed through official communication channels that have been verified.
The quake at a depth of 15 kilometers in Mindanao-Philippines is approximately 388 kilometers northwest of Melonguane, Talaud Islands Regency, North Sulawesi.
