Analisis BMKG soal Gempa M 5,1 Guncang Palu

A magnitude 4.9 earthquake struck 54 km southeast of Palu, Central Sulawesi, on June 17, 2026. According to Wijayanto, Director of Earthquakes and Tsunami at BMKG, the shallow tremor resulted from active fault activity and carried no potential for a tsunami.

The BMKG initially recorded the event as a magnitude 5.1 earthquake before updating the parameter to M 4.9. The epicenter was located at coordinates 1.11° S; 120.32° E at a depth of 11 km.

Where was the earthquake felt?

The tremor was felt across several regions with varying intensities. Balinggi in Parigi Moutong recorded a scale of V MMI, while Palolo, Sigi, and Torue in Parigi Moutong experienced intensities between IV and V MMI.

Lower intensities were reported in other areas. Kota Sigi Biromaru and Kota Poso recorded III MMI, Kota Palu saw II-III MMI, and Kota Donggala and Kota Pasangkayu recorded II MMI.

Did You Know? By 02:00 WIB on June 17, 2026, BMKG monitoring recorded 354 aftershock activities following a larger M 6.7 earthquake that hit Palu on June 16.

Why did this earthquake occur?

Wijayanto stated the earthquake was a shallow tremor caused by active fault activity. Analysis of the source mechanism indicates the movement was a “normal fault,” characterized by a downward shift.

This event is part of a series of aftershocks from a magnitude 6.7 earthquake that occurred in Palu on June 16, 2026, at 10:27:45 WIB. The largest among the subsequent aftershocks reached magnitude 5.2.

Expert Insight: Samantha Carter notes that the combination of a shallow depth (11 km) and a normal fault mechanism typically explains why tremors are felt sharply at the surface, though the lack of tsunami potential in this instance is tied to the specific epicenter location and movement type.

What happens next for the Palu region?

BMKG has urged the public to remain calm and ignore unverified information. Because this is a sequence of aftershocks, further tremors could occur as the crust adjusts following the M 6.7 event.

While no damage has been reported yet, residents may continue to feel lower-magnitude shakes. Monitoring is likely to continue as the agency tracks the activity of the active fault.
