Social media users in Jakarta reported hearing two loud rumbles of unknown origin on Sunday evening. Some claimed that the sound – described as resembling distant thunder – was significant enough to have rattled objects in their homes.

Twitter users reported that the sound was heard twice at around 7:45 p.m. Others in Greater Jakarta, including Tangerang, Banten, reported a similar noise the following morning at about 5:30 a.m.

As of Monday morning, the hashtag #dentuman (#thunder) was a national trending topic with more than 4,200 tweets.

According to the Meteorology, Climatology and Geophysics Agency (BMKG), the sound was likely produced by thunder over Mount Salak in Bogor, West Java.

“The result of BMKG’s inspection using lightning detectors shows a number of lightning-related activities around Mount Salak between 7 p.m. and 9 p.m.,” BMKG tsunami and earthquake mitigation head Daryono told kompas.com on Sunday.

He said the noise was not produced by seismic activity, adding that it was possible that similar sounds would be heard in the future.

In April, residents of Greater Jakarta reported a similar rumbling noise, stoking fears of a volcanic eruption at Anak Krakatau amid the ongoing COVID-19 emergency.

Although the source of the previous sound remains unknown, the Volcanology and Geological Hazard Mitigation Center (PVMBG) determined that it did not come from the active volcano. (rfa)
