Total energy released based on mb readings = 40078.21 tons of TNT equivalent to a single 6.283mb quake, or using the Geofon/EMSC mb-Mw conversion formula (Mw = 0.7813mb + 1.5175), 6.426Mw

The current swarm is located within 35km SE of the 1918/09/07 Mag 8.2Ms and 1967/03/19 Mag 7.0Mw earthquakes and within 60km NE of the 1918/11/08 Mag 7.7Ms earthquake
