7.7-7.8 magnitude earthquake and tsunami warning in Indonesia’s Flores region
Consensus Summary
A powerful earthquake struck Indonesia’s Flores region early on Saturday, with the Guardian reporting a 7.7-magnitude quake at 10km depth and ABC reporting a 7.8-magnitude quake at 35 kilometres depth. Both sources confirm the epicentre was 68km north-northwest of Ende in East Nusa Tenggara province, triggering a tsunami warning from Indonesia’s BMKG for coastal regions. The Guardian details immediate evacuations, aftershocks including a 6.1-magnitude tremor, and waves detected between 19 and 30 centimetres, while ABC notes no immediate casualties or damage. Australia’s tsunami warning centre ruled out any threat to its mainland or territories. Indonesia’s vulnerability to seismic activity due to its location on the Ring of Fire was highlighted by both outlets.
