A 6.7 magnitude earthquake struck off Indonesia on Tuesday, and people in Palu felt strong shaking for more than a minute as Earthquake Near Me searches spiked around the city. Hospitals evacuated patients outside as a safety measure after the quake, which also sent strong aftershocks through the area.
The quake was centred 46 kilometres east-southeast of Palu and about 10 kilometres deep, according to the US Geological Survey. Palu has about 400,000 people and is the capital of Central Sulawesi province, so even a short burst of severe shaking reaches a large city quickly.
Palu and the immediate response
Hospitals moved patients outside after the shaking, and scattered damage was reported. The sequence matters for residents trying to judge whether they can stay inside damaged buildings or need to wait for inspections, because the first minutes after the main tremor were still unsettled by stronger follow-on quakes.
The strongest subsequent quakes measured 5.2 magnitude, 5.0 magnitude and 4.9 magnitude. Those aftershocks did not bring any additional reported outcomes in the available information, but they extend the period when weakened walls, glass and utility lines can fail even after the main shaking ends.
Indonesia seismic faults
Indonesia is crossed by several seismic faults, and earthquakes and volcanic activity are common there. That background helps explain why a 6.7 magnitude event off Indonesia draws immediate attention in Palu and beyond, especially when the shaking lasts more than a minute and sends hospital patients outdoors.
In January 2021, a magnitude 6.2 earthquake near Mamuju on Sulawesi island left at least 100 people dead. Against that recent history, this Tuesday’s quake looks less like an isolated jolt and more like another reminder that strong shaking in Sulawesi can turn quickly into a public-safety problem for large numbers of people.
US Geological Survey quake depth
The US Geological Survey said the quake was about 10 kilometres deep, which places the rupture close enough to the surface for shaking to be felt widely across the city. Whether the 6.7 magnitude earthquake caused injuries or deaths is not stated in the source, and readers in Palu will need further updates before they can judge the full toll.
