Magnitude 6.7 earthquake hits Palu in Indonesia
A powerful 6.7 magnitude quake struck Sulawesi near Palu on Tuesday, the city devastated by disaster in 2018. At least eight people were hurt, and officials ruled out a tsunami threat.
- A magnitude 6.7 earthquake struck Sulawesi on Tuesday, with its epicenter about 43 kilometers east-southeast of Palu at a depth of roughly 10 kilometers.
- At least eight people were injured in Sigi district, two of them seriously, while several hospitals evacuated patients as a precaution.
- Indonesia's agency ruled out a tsunami threat but warned of aftershocks; the strongest so far measured magnitude 5.2.
- Three districts with about 1.2 million residents are under damage assessment, in a city still scarred by the 2018 disaster.
A powerful magnitude 6.7 earthquake struck the Indonesian island of Sulawesi near the city of Palu on Tuesday, reviving memories of the catastrophe that flattened the same place eight years ago. Serbia sits far from the Pacific seismic belt, yet this story carries a lesson for us too: it shows how a country copes with repeated trauma on the same ground, and how quickly civil protection must respond when the earth shifts beneath a densely populated coast.
According to Indonesian seismologists, the epicenter lay about 43 kilometers east-southeast of Palu, at a relatively shallow depth of roughly 10 kilometers. Shallow quakes of that strength transfer more energy to the surface, which explains why roofs collapsed and walls cracked in the city even though the epicenter was not directly beneath it. At least eight people were injured in the neighboring district of Sigi, two of them seriously.
Authorities almost immediately announced there was no tsunami threat, a sensitive subject in Palu. A warning nonetheless remained in place for aftershocks, of which there were several; the strongest measured magnitude 5.2. Several health facilities moved patients outdoors as a precaution, and three districts home to roughly 1.2 million people were placed under damage assessment.
Why is Palu so vulnerable to quakes like this?
Palu is no accidental focus for seismologists. An active fault runs through the valley where it sits, and the coast is shaped by a narrow bay that can amplify a wave if one forms. That is exactly what happened in 2018, when a magnitude 7.5 quake triggered a tsunami and so-called soil liquefaction, in which solid ground began to behave like liquid and swallowed entire neighborhoods. More than 4,000 people died in that disaster.
That is why every new quake in Palu carries a double burden: physical damage and collective memory. A hotel manager in the city described the mood after Tuesday this way: “Everyone panicked, which is a natural reaction during an earthquake, but everyone is safe.” That sentence captures the difference between 2018 and today. An early warning system, faster hospital evacuations, and a clear message that no tsunami was coming are all lessons paid for at the highest price.
How do we measure a successful response to a disaster like this?
So far the authorities’ response appears to have been fast and disciplined, an important sign. Evacuating hospitals as a precaution, rather than only after a collapse, suggests protocols have been tightened. Assessing damage across three districts of more than a million people will take days, since only field teams can determine how many buildings were truly affected and whether infrastructure suffered hidden damage.
Indonesia lies along the so-called Ring of Fire, a belt of intense seismic and volcanic activity, so quakes are part of daily life there. The difference between a mishap and a catastrophe is often not the strength of the quake but how prepared society is to respond. Palu learned that the hardest way, and Tuesday was a test of how much had been learned.
How well would our own civil protection system withstand a similar blow, and do we think about it only when the earth shakes somewhere far away?
