Jakarta - The Meteorology, Climatology and Geophysics Agency stated that active fault activity on the seabed triggered the shallow tectonic earthquake that rocked Central Lombok, West Nusa Tenggara, early Thursday morning.
Director of the BMKG Earthquake and Tsunami Center, Daryono, in Jakarta, Thursday, said that the earthquake was detected as having its epicenter on land at a depth of 27 kilometers at a distance of 85 km from the west of Central Lombok, West Nusa Tenggara.
"Located on land at a distance of 85 kilometers west of Central Lombok at a depth of 27 km. This earthquake had a magnitude of 4.2," he said.
The earthquake was detected shaking a number of areas for several moments at 00.32 WITA with an Intensity II MMI scale, starting from Mataram City, West Lombok, Central Lombok, to Badung Regency, Gianyar, and Denpasar City in Bali.
He said that the distribution of earthquake areas was based on reports from people who felt the tremors.
However, BMKG confirmed that based on seismological analysis, the earthquake did not have the potential to cause a tsunami.
BMKG has not yet received any reports of damage caused by the earthquake, including aftershocks detected at least until 00.46 WITA.
