Yogyakarta, IndonesiaSentinel.com — The Meteorology, Climatology, and Geophysics Agency (BMKG) has recorded a total of 329 aftershocks in Gunung Kidul, Yogyakarta, following a series of earthquakes in the region.
“As of Saturday (September 14) at 6:00 AM WIB, BMKG’s monitoring results indicate that these tremors are part of the aftershock series from the Gunung Kidul earthquake, which measured a magnitude of 5.8 and occurred on Monday (August 26) at 7:57 PM WIB. A total of 329 aftershocks have been recorded so far,” explained Daryono, the Head of BMKG’s Earthquake and Tsunami Center, in an official statement on Saturday (September 14).
The most recent aftershock struck on Saturday (September 14) at 12:19 AM WIB with a magnitude of 4.9.
“The epicenter of this Yogyakarta aftershock was located at the coordinates 9.15° S and 110.40° E, precisely in the sea, 130 km southwest of Gunung Kidul, Yogyakarta, at a depth of 5 km,” Daryono added.
The tremors were reportedly felt in several surrounding areas, including Pacitan, Wonogiri, and Sukoharjo with intensities ranging between II and III on the Modified Mercalli Intensity (MMI) scale. The quake was strong enough to cause light objects to sway and some residents described the vibrations as similar to the passing of a large truck.
Fortunately, there have been no reports of significant damage from the latest aftershock.
According to additional data from BMKG, the seismic activity in the Gunung Kidul region has been persistent since the major earthquake in late August. This ongoing activity has raised concerns about the potential for future quakes, though experts emphasize that most aftershocks are of lower magnitude compared to the initial tremor.

Residents of Yogyakarta and nearby regions are advised to remain vigilant and stay updated on further developments. BMKG continues to monitor the situation and provides regular updates on seismic activity across Indonesia.
In addition to the aftershocks, the agency has reminded residents to prepare for the possibility of more tremors as aftershock sequences can last for several weeks or even months following a significant earthquake event.
