Suara.com – The Meteorology, Climatology and Geophysics Agency (BMKG) said that the 6.3 magnitude earthquake that rocked the east coast of the Talaud Islands, North Sulawesi had no potential for a tsunami.
“The modeling results show that this earthquake does not have the potential for a tsunami,” said Head of the BMKG Earthquake and Tsunami Center, Daryono in Newsdelivers.com, Tuesday (26/9/2023).
He said, the epicenter of the earthquake was located at coordinates 4.60 north latitude and 127.41 east longitude, or precisely located in the sea at a distance of 40 km southeast of Karatung Island, North Sulawesi at a depth of 109 km.
“By paying attention to the location of the epicenter and the depth of the hypocenter, the earthquake that occurred was a medium-sized earthquake due to plate subduction activity,” he explained.

He added that the results of the source mechanism analysis showed that the earthquake had an upward movement mechanism (thrust fault).
He stated that the earthquake that occurred at 08.39.47 WIB had updated parameters of M6.1 and was felt in the Talaud area with an intensity scale of III-IV MMI (modified mercury intensity), meaning that during the day it was felt by many people inside the house, outside by several people, broken pottery, windows/doors rattling and walls making sounds.
The earthquake was also felt in the Siau and Tahuna areas with an intensity scale of III MMI (the vibrations were felt clearly in the house, the vibrations were felt as if a truck was passing by).
“Until now there have been no reports of the impact of the damage caused by the earthquake,” said Daryono.
He added that as of 08.55 WIB, BMKG monitoring results had not shown any aftershock activity.

He appealed to the public to avoid buildings that were cracked or damaged by the earthquake.
“Check and ensure that the building where you live is earthquake-resistant enough, or that there is no damage due to earthquake vibrations that endangers the stability of the building before you return to the house,” he said.
In addition, he also appealed to the community to remain calm and not be influenced by issues whose truth cannot be accounted for.
