Last month, a 7.4-magnitude earthquake struck Sulawesi Island, which triggered a tsunami in the cities of Donggala and Palu that towered up to 10 feet (3 meters) high.
Indonesia lies within the Pacific Ocean’s "Ring of Fire" where tectonic plates collide and cause frequent seismic and volcanic activity.
On Dec. 26, 2004, a magnitude 9.1 earthquake struck the eastern coast of Sumatra, triggering a tsunami that killed around 230,000 people as it tore along the coasts of Sri Lanka, India, Malaysia, Indonesia and Thailand.
