Magnitude 4.3 earthquake · MPanama

VExpected intensity: Moderate: felt by nearly everyone, small objects fell

Expected intensity

MMI II ≤ 87 km
MMI III ≤ 40 km
MMI IV ≤ 18 km
MMI V ≤ 5.0 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.

Aftershocks

Earthquakes within 20 km of the epicentre in the first 30 days.

Count: 6

Aftershock forecast

The chance of an aftershock of magnitude 4 or more in the next 7 days is 17%, and of magnitude 5 or more 2%.

The chance of an aftershock of magnitude 3 or more in the next 24 hours is 50%.

≈ expected number of aftershocks

1 aftershock recorded so far within 10 km (1 of M3.3 or more).

Computed: 10 Oct 2026, 01:28 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 = -1.819)

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