YOGYAKARTA The islands of the Gods of Bali and the island of Lombok were rocked by an earthquake with a magnitude of 5.5 on Tuesday, May 14, at around 15.11 WIB or around 16.11 WITA.
Reporting from Antara, the Meteorology, Climatology and Geophysics Agency (BMKG) noted that the epicenters felt up to Bali and Lombok were the Lombok Strait at coordinates 8.4 south latitude (LS) and 116.03 east longitude (BT) with a location at sea with a distance of 15 km southwest of Lombok north of 10 km depth.
According to information from the Head of the BMKG Earthquake and Tsunami Center, Daryono, in a press release, Tuesday, May 14, the earthquake that occurred did not cause a tsunami.
"By paying attention to the location of the epicenter and the depth of the hypocentrum, the earthquake that occurred was a shallow type of earthquake due to the activity of the fault rising north of Lombok (Lombok back arc thrusting). The results of the analysis of the source mechanism show that the earthquake has an upward movement mechanism," said Daryono.
Please note, rising faults or reverse faults occur usually marked by one of the existing rock blocks that have shifted upwards while other rock blocks have shifted downwards.
The location of the reverse fault itself usually occurs in areas where two tectonic plates collide with each other. In the rising fault, the direction of the maximum rock force occurs horizontally. The force-suppressed Battuan triggered one part of the rock to move towards the top. Meanwhile, the rising fault area is characterized by the presence of a mountain belt.
Earthquake tremors were felt in several areas, namely Mataram City, East Lombok, West Lombok, Central Lombok, North Lombok, West Sumbawa, Sumbawa, Badung, Denpasar, Karangasem, Bangli, on an intensity scale of III MMI so that vibrations were felt enough when inside the house. Earthquake vibrations resemble vibrations when a large truck passes through the streets.
In addition, in the Tabanan area, the intensity scale of MMI II is so that vibrations are felt. Objects hanging on the wall will be seen swaying from the vibration effect.
Although there is no potential for a tsunami, people are advised to remain calm and not panic about wild issues spread by irresponsible persons. It is recommended that the public avoid buildings that have the potential to collapse or collapse due to earthquake vibrations to minimize falling debris from buildings.
Reporting from Antara, the tremors that were felt up to Denpasar occurred with a fairly short duration of about two to three seconds. The tremors were also felt by several employees and customers of one of the private banks in Renon, Denpasar.
