Terremoto mayor magnitud 6.7 - North Pacific Ocean, 85 km S of David, Provincia de Chiriqui, Panama, jueves, 20 oct 2022 06:57 (GMT -5) -

A magnitude 6.9 earthquake near David, Distrito de David, Provincia de Chiriqui, Panama, was reported only 15 minutes ago by the United States Geological Survey, considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at a shallow depth of 10 km beneath the epicenter early morning on Thursday, October 20th, 2022, at 6:57 am local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
A second report was later issued by The Incorporated Research Institutions for Seismology (IRIS), which listed it as a magnitude 6.9 earthquake as well. Other agencies reporting the same quake include Geoscience Australia (GeoAu) at magnitude 6.5, the German Research Centre for Geosciences (GFZ) at magnitude 6.5, the citizen-seismograph network of RaspberryShake at magnitude 6.9, and the European-Mediterranean Seismological Centre (EMSC) at magnitude 6.7.
Based on the preliminary seismic data, the quake should have been widely felt by almost everyone in the area of the epicenter. It might have caused light to moderate damage.
Moderate shaking probably occurred in Boca Chica (pop. 220) located 59 km from the epicenter, Pedregal (pop. 17,400) 77 km away, Las Lomas (pop. 11,700) 82 km away, David (pop. 82,000) 82 km away, San Pablo Viejo Abajo (pop. 6,000) 87 km away, Puerto Armuelles (pop. 11,700) 89 km away, El Palmar (pop. 4,500) 91 km away, and Concepcion (pop. 17,700) 98 km away.
In Santiago (pop. 45,400) located 152 km from the epicenter, the quake should have been felt as light shaking.

Based on its magnitude, the fault that was active during the quake ruptured along a surface of approx. 501 km² (=194 sqare miles) as a first-order estimate. The length of the rupture zone thus was probably around 39 km (24 mi).
Aftershocks typically occur during the weeks and months following the quake at or near the same fault, at distances of up to approx. two times the length of the rupture zone.
The often broadly linear arrangement of aftershock epicenters encompasses the rupture zone of the main shock (check on the map below to verify).
