The 1993 Finisterre Range earthquakes began on October 13 with a Mw 6.9 mainshock,[2] followed by Mw 6.5 and 6.7 earthquakes.[4] These earthquakes struck beneath the Finisterre Range, north of Markham Valley in Morobe Province, Papua New Guinea. The complex earthquake sequence seriously damaged many villages in the rural Eastern Papua New Guinea region, generating landslides and killing at least 60 people.
