≈ expected number of aftershocks

1 aftershock recorded so far within 10 km (1 of M3.7 or more).

Computed: . Method: Reasenberg-Jones (generic, Bayesian a-value update); regime ANSR-DEEPCON; 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 = -1.933)

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