Expected intensity

MMI II ≤ 118 km
MMI III ≤ 50 km
MMI IV ≤ 10 km

Rings show the expected Modified Mercalli (MMI) intensity from the Akkar–Sandıkkaya–Bommer (2014) ground-motion model converted with Worden et al. (2012). Real shaking depends on soil and building.

≈ expected number of aftershocks

0 aftershocks recorded so far within 10 km (0 of M3.6 or more).

Computed: 6 Oct 2026, 04:03 UTC. Method: Reasenberg-Jones (generic, Bayesian a-value update); regime ANSR-SHALCON; generic parameters Page et al. (2016) via USGS OpenSHA GenericRJ_ParametersFetch.json. Probabilities are updated with the recorded aftershocks on every request. (b = 1, p = 0.98, c = 0.018 days, a = -2.723)

This is a statistical forecast, not an earthquake prediction. Actual aftershock activity can differ; follow local authorities for official statements.
