As reported by Kompas (1/7/2023), an earthquake with a magnitude of 6 shook Bantul Regency, DIY, Friday (30/6/2023) night. As a result, one person was reported killed, 6 people were injured, and dozens of buildings were damaged.

BMKG declared that the strength of the earthquake in Bantul reached M 6.4 with a depth of 25 kilometers and occurred at 19:57:43. However, this was later updated to M 6 with a depth of 68 kilometers. This earthquake did not trigger a tsunami.

A number of broken roof tiles were seen in the Taman Budaya Gunungkidul area in Gunungkidul Regency, Special Region of Yogyakarta, on Saturday (1/6/2023). The building is one of those affected by a 6 magnitude earthquake on Friday (30/6) night. The damage to the building includes cracked walls, collapsing ceilings, and falling roof tiles.

Asmoro Widagdo, who is also a member of the earthquake and tsunami researchers from IAGI (Indonesian Association of Geologists), said that Bantul, like other areas along the southern coast of Java, is prone to earthquakes. This is related to its location which is on the earthquake belt caused by the subduction of the Indian Ocean plate beneath Java Island.

"Indeed, Bantul and its surroundings are areas with highly active tectonics," he said.

Efforts to familiarize the community with various threats, especially earthquakes, need to be instilled since elementary education.

At least, according to Asmoro, there are three recognizable sources of faults in the area. The first is underwater faults caused by the subduction of the Indian Ocean plate beneath Java. This plate subduction creates a threat of large earthquakes that can occur at any time.

Secondly, the pathway to the Opak fault channel towards the south of Java. The third one is located towards the west, on the Kulon Progo fault from land towards the sea. This fault also poses a threat of an earthquake.

"Considering the possibility of earthquake scale and the configuration of the faults, these three fault lines provide a possibility of the formation of a tsunami if it occurs under the sea," stated Asmoro.

According to him/her, education on the threat of these fractures needs to be carried out towards the community. Efforts to familiarize the community with various threats, especially earthquakes, need to be instilled since elementary education.

The public needs to face earthquake and other disasters proportionally. Hence, appropriate steps in earthquake disaster mitigation can be optimally carried out.
