Quick Analysis
According to the epicenter of the quake, this is an underwater quake. Based on the hypocenter, an underwater landslide is conceivable and could trigger a tsunami. Based on the data received, using the depth of the hypocenter, a potential tsunami will reach the nearest (Kimbe, West New Britain, Papua New Guinea) settlement within 02:07.
