Indonesia straddle the Pacific Ring of Fire, where different tectonic plates of the Earth’s crust meet and create frequent seismic activity, causing them to experience frequent earthquakes. The Ring of Fire is along the northeastern islands adjacent of New Guinea and the Alpide belt along the south and west from Sumatra, Java, Bali, Flores, and Timor. The motion of the fault generates numerous small earthquakes on a daily basis. In 2004, a 9.1-magnitude quake triggered a tsunami that killed 220,000 throughout the region, including about 170,000 in Indonesia. — Agencies
