Expected intensity

8 km NW of Río Grande, PanamaNatural Earth
  • MMI II ≤ 700 km
  • MMI III ≤ 700 km
  • MMI IV ≤ 321 km
  • MMI V ≤ 150 km
  • MMI VI ≤ 69 km
  • MMI VII ≤ 29 km
  • MMI VIII ≤ 2.0 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 80 km of the epicentre in the first 30 days.

Count: 15

Aftershock forecast

The chance of an aftershock of magnitude 4 or more in the next 7 days is 100%, and of magnitude 5 or more 91%.
The chance of an aftershock of magnitude 3 or more in the next 24 hours is 100%.

≈ expected number of aftershocks

13 aftershocks recorded so far within 35 km (7 of M4.5 or more).

Computed: . 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 = -2.01)

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