History

Historical Context

The 26 December 2004 Sumatra–Andaman megathrust, recorded by the USGS at magnitude 9.2–9.3, killed an estimated 227,898 people across fourteen nations and spurred Indonesia to overhaul disaster response. That legacy guided authorities during the 6 June 2026 magnitude-6.7 Sulawesi quake, prompting swift alerts and coordinated relief under the Pacific Ring of Fire’s ongoing risk.
