The outcome of source mechanism analysis reveals the earthquake had flat motion system. By 5.30 p.m. on Monday (October 19, 2020), there has actually been an aftershock of magnitude 3.2.
Banda Aceh, Aceh – An earthquake measuring 5.4 on the Richter scale was reported from the westernmost Indonesian province of Aceh on Monday evening, though no tsunami warning was released, according to the regional geophysics station.
The epicenter of the earthquake– which broke out at 4.38 p.m. local time– lay in the sea, 49 kilometers north of the Simeulue district capital of Sinabang and at a depth of 10 km, chief of the Aceh Besar Geophysics Station, Djati Cipto Kuncoro, informed.
Kuncoro said he was waiting for the report on the damage triggered by the earthquake.
Based on its epicenter and hypocenter depth, the earthquake was a shallow earthquake triggered by subduction underneath Sumatra Island, according to the Meteorology, Climatology, and Geophysics Firm (BMKG).
” The outcome of source mechanism analysis reveals the earthquake had flat movement mechanism. By 5.30 p.m. on Monday (October 19, 2020), there has been an aftershock of magnitude 3.2,” Kuncoro said.

Aceh had borne the brunt of a 9.1-magnitude quake and subsequent tsunami on December 26, 2004, which had actually led to numerous countless people losing their lives or going missing out on.
Indonesia is found on the geographically active Pacific Ring of Fire and holds some 40 percent of the world’s geothermal reserves.
According to Live Science, the Ring of Fire, or the Circum-Pacific belt, is the world’s greatest earthquake belt owing to the existence of geological fault ranging from Chile to Japan and Southeast Asia
