BMKG: Megathrust Activities Cause Tectonic Earthquakes In Aceh
JAKARTA - The Meteorology, Climatology and Geophysics Agency (BMKG) reported that the megathrust activity of sea plates has caused tectonic earthquakes in Aceh Singkil Regency, Aceh today."The earthquake that occurred was a shallow type of earthquake due to megathrust activity," said Head of the Center for Meteorology, Climatology and Geophysics Region I Hendro Nugroho in an official statement received in Jakarta, Antara, Friday, February 16.He explained that megathrust activity was caused by a buildup of pressure along the boundaries of the sea plate and then when this pressure was released, the plates suddenly moved to cause an earthquake.Based on BMKG analysis, the epicenter of the 4.4 magnitude earthquake was located at sea 21 kilometers southeast of Aceh Singkil Regency at a depth of 31 kilometers.The earthquake had an impact and was felt in Aceh Singkil Regency with an intensity scale of III-IV MMI or during the day felt by many people at home, outside by several people, broken pottery, windows and doors tightened and walls sounded.The tremors of the earthquake were also felt by people in Subulussalam City with an intensity scale of III MMI or vibrations felt real in the house, as if a truck had passed.However, he confirmed that until now there have been no reports of damage to buildings as a result of the earthquake.Based on the results of the tsunami modeling with the source of the tectonic earthquake at coordinates 2.15 degrees LU - 97.85 degrees southeastern BT Aceh Singkil, there is no potential for a tsunami."The monitoring results until 15:38 WIB showed that there had been no aftershocks," he said.BMKG appealed to the local community to remain calm and not be influenced by issues that cannot be justified.
In addition, Hendro hopes that the community will ensure that the residential buildings are earthquake-resistant enough or that there is no damage due to vibrations that endanger the stability of the building so that it is safe from the potential collapse of buildings caused by the earthquake.
