A powerful earthquake registered by both the USGS and EMSC as M7.0 hit Papua New Guinea’s New Britain Region at 20:48 UTC on October 10, 2018. The USGS is reporting a depth of 40.3 km (25 miles).
The quake was preceded by a M6.1 at 20:45, and followed by a M5.9 at 20:59 — further aftershocks have been recorded.
The epicenter was located 118.3 km (73.5 miles) E of Kimbe (population 18,847) and 188 km (117 miles) NE of Kokopo (population 26,273).
Tsunami waves were forecast though were less than 30cm (11.8 inches) above the tide level for the coasts of Papua New Guinea and the Solomon Islands.
PTWC oceanographer David Walsh said any tsunami from the earthquake only affected areas immediately around the epicenter.
The threat is now over.
The recent global seismic and volcanic uptick is likely attributed to the drop-off in solar activity, coronal holes, and the increase in Galactic Cosmic Rays penetrating silica-rich magma.
