On 28 September 2018, central Sulawesi in Indonesia got struck by a powerful earthquake measuring 7.5 in magnitude (M). A tsunami that followed later devastated the city of Palu and the town of Donggala, leaving more than a thousand dead and even more homeless.

Associate Professor Adam Switzer, a Principal Investigator at the Earth Observatory, shares with us why this earthquake-tsunami event is a complicated one and what you can do to stay as safe as possible if you were ever caught up in one.
