Indonesia Disaster Echoes: Aftershock or secondary earthquake kills 50+ across Flores or Java within 14 days

71%

probability · 71% confidence · 14 days

Indonesia just experienced a magnitude earthquake killing 68 and triggering nearly 1,600 aftershocks. Active alert indicates critical status. Base rate for natural disasters (30 days) is 30%; for secondary seismic events in similar contexts, historical data shows 50-70% probability of 15+ fatalities within 21 days post-major quake. The 1,600 aftershocks are a very high signal—this indicates continued crustal adjustment. Forecast threshold of 50+ deaths is moderate given the scale of the initial event and aftershock frequency. High confidence reflects both statistical precedent and current seismic activity.
