Jakarta (ANTARA) - Rock deformation in the Indo-Australian ocean plate caused a 5.1-magnitude (M) earthquake in the south of East Java and the Malang region on Tuesday at 11:36 a.m. local time.

"By observing the epicenter and the hypocenter, the earthquake that struck was an intraslab type, with an intermediate depth, due to rock deformation in the Indo-Australian ocean plate," Head of the Meteorology, Climatology, and Geophysics Agency's (BMKG's) Earthquake and Tsunami Center Daryono stated here on Tuesday.

He noted that the earthquake's epicenter was located at the coordinates of 9.14 degrees south latitude and 112.48 degrees east longitude, 65 km undersea and 111 km southwest of Malang District, East Java.

The analysis results showed that the earthquake had a thrust fault mechanism.

"The results of the BMKG analysis also showed that this earthquake has an updated parameter, with a magnitude of 4.8," Daryono stated.

He explained that this earthquake was felt in the Karangkates area, Sumbermanjing Wetan Sub-District, at an intensity of III-IV on the Modified Mercalli Intensity (MMI) scale, or meaning that the tremors were felt indoors.

Meanwhile, the quake was felt with an intensity of MMI II-III in Kepanjen, Lumajang, and Malang, where light objects swayed and some people felt the tremors.

The earthquake was also felt in the Badung, Blitar, Trenggalek, Pacitan, and Bondowoso areas, with an intensity scale of MMI II.

"The modeling results showed that this earthquake did not potentially cause a tsunami," Daryono stated.

As of 12 p.m. Western Indonesian Standard Time (WIB), the BMKG monitoring results had not shown any aftershock activity.

Nevertheless, he urged the public to remain calm and not be influenced by unreliable information and avoid buildings that are cracked or damaged due to the earthquake.

"Check and make sure your house is earthquake resistant or there is no damage due to the earthquake that endangers the stability of the building before returning,” he cautioned.
