JAKARTA - The Meteorology, Climatology and Geophysics Agency (BMKG) noted that 53 aftershocks occurred after an earthquake with a magnitude of 6 rocked Bantul, Yogyakarta Special Region on Friday (30/6) night.

"As of this morning, BMKG recorded 53 aftershocks in South DIY," said Head of the BMKG Earthquake and Tsunami Center Daryono as quoted by Antara, Sunday.

He added that there were aftershocks with the largest magnitude, namely M 4.2 and the smallest M 2.7 until 07.00 WIB.

He said the epicenter of the earthquake that occurred in the Indian Ocean was a reminder of the existence of a subduction zone that was still active in the southern region of Java Island.

He said the active subduction zone could not only cause an earthquake, but also a tsunami.

He explained that tsunami historical records in the south of Java Island had occurred eight times with details of 1818, 1840, 1859, 1904, 1921, 1957, 1994 in Banyuwangi, and 2006 in Pangandaran.

"This is an important note related to the potential and dangers of earthquakes and tsunamis in the south of Yogyakarta and south of Java in general," said Daryono.

Previously, the Head of BMKG Dwikorita Karnawati said that aftershocks after the earthquake with a magnitude of 6 were not felt by humans.

"So there was no aftershock at all, only tools were recorded," he said.

He asked the public to avoid buildings that were damaged in a post-earthquake structure last Friday (30/6) night.

He said the public must also be aware of aftershocks that have the potential to cause damage to buildings that have been cracked or damaged.

"We ask the public not to occupy buildings that are structurally damaged," said Dwikorita.
