JAKARTA: A strong 6.8 magnitude earthquake rocked eastern Indonesia Friday, the United States Geological Survey said, triggering a tsunami warning and sending panicked residents running from their homes.
The quake struck at a relatively shallow depth of 17 kilometres off the east coast of Sulawesi island, the USGS said, where a 7.5-magnitude quake-tsunami around the city of Palu killed more than 4,300 people last year.
Indonesia’s geophysics agency issued a tsunami warning for coastal communities in Morowali district, but there were not immediate reports of casualties or damage.
But the USGS warned that considerable damage was possible in poorly built or badly designed structures.
The quake hit off the coast of eastern Sulawesi, on the other side of the island from disaster-hit Palu.
Indonesia is one of the most disaster-prone nations on Earth due to its position straddling the so-called Pacific Ring of Fire, where tectonic plates collide.
The sprawling archipelago is also lined with over 100 volcanoes.
At the end of last year, an erupting volcano in the middle of the Sunda Strait between Java and Sumatra islands killed more than 400 people.
