Tsunami Warning: 7.7 Quake Strikes Indonesia
7 earthquake has struck off the coast of Indonesia's Flores region, triggering an immediate tsunami warning across one of Southeast Asia's most seismically active zones, according to the US Geological Survey and reporting from The Guardian.
A magnitude 7.7 earthquake has struck off the coast of Indonesia's Flores region, triggering an immediate tsunami warning across one of Southeast Asia's most seismically active zones, according to the US Geological Survey and reporting from The Guardian.
The quake hit at a shallow depth of ten kilometres — shallow enough to transfer its full force directly into the ocean column above it. Shallow-focus earthquakes of this magnitude are the ones that move water. Authorities issued the tsunami warning within minutes of the strike, with coastal communities along Flores put on immediate alert.
Flores sits inside the arc of Indonesia's outer islands, a chain of volcanic and seismically restless terrain that has produced some of the most destructive tsunamis in recorded history. The region draws significant numbers of British and European tourists, adding a consular dimension to what is already a major humanitarian concern.
No immediate casualties had been confirmed at the time of reporting, per The Mirror, though evacuation procedures were underway along affected coastlines. The depth reading of ten kilometres places this event in the category that emergency planners fear most — fast onset, wide wave propagation, minimal warning time for communities close to the epicentre.
Indonesia sits on the Pacific Ring of Fire. It does not ask permission before reminding the world of that fact.
The tsunami warning remains active. Coastal populations have been urged to move to higher ground and await official clearance before returning.
