JAKARTA, NETRALNEWS.COM - Head of Earthquake and Tsunami Center of the Indonesian Meteorology, Climatology and Geophysics Agency (BMKG) Rahmat Triyono reports that on Monday, April 1, 2019, a tectonic earthquake shook the Nicobar Islands again.

The BMKG analysis results show that the earthquake occurred at 15.11.35 WIB with the power M = 5.5 which was later updated to Mw = 5.4.

The epicenter of the earthquake is located at the coordinates 7.57 LU and 94.28 BT, or precisely located at sea at a distance of 219 km northwest of Sabang City, Aceh Province at a depth of 10 km.

"Taking into account the location of the epicenter and the depth of hypocenter, the earthquake that occurs is a type of shallow earthquake due to submarine magnification activities. The analysis of the source mechanism shows that earthquakes in the sea region of the Nicobar Islands are generated by rock deformation with a mechanism of movement of a sliding fault structure (Strike Slip Fault), "explained Rahmat in a written statement that Netralnews received.

Rahmat said, the impact of the earthquake based on community reports and the Shakemap BMKG Map showed that shocks were felt in the MMI Banda Aceh II.

"Until now there has been no report of the impact of the damage caused by the earthquake. The modeling results show that the earthquake did not have the potential for a tsunami," said Rahmat.

As of 15.48 Indonesian western time, BMKG monitoring results have not shown any aftershock activity. The community is encouraged to remain calm and not be affected by issues that cannot be justified.

Rahmat appealed to the public to ensure that official information only came from BMKG which was distributed through verified official communication channels (Instagram / Twitter @infoBMKG), the website (http://www.bmkg.go.id or inatews.bmkg.go.id), or through Mobile Apps (IOS and Android): wrs-bmkg (pemda user, pwd pemda-bmkg) or infobmkg.
