Pacific Ring of Fire
Straddling the so-called Pacific Ring of Fire, Indonesia is regularly hit by earthquakes.
In 2018, a devastating 6.2-magnitude quake and subsequent tsunami struck the city of Palu, in Sulawesi, killing thousands.
A 9.1 magnitude quake off the north of Indonesia's Sumatra island on Boxing Day 2004 triggered a tsunami that swept over coastal areas of Indonesia, Sri Lanka, India, Thailand and nine other countries, killing more than 230,000 people.
In January last year, at least 35 people were killed after a 6.2-magnitude earthquake struck Indonesia's Sulawesi island.
