The 1986 Kalamata earthquake struck the southern Peloponnese Region of Greece on September 13 at 20:24 local time. The 12.5 km (7.8 mi) deep moment magnitude (Mw) 5.9 earthquake had an epicenter near the coastal city of Kalamata and was assigned X (Extreme) on the Mercalli intensity scale. The earthquake resulted from normal faulting along a northwest-dipping fault and produced surface ruptures. Extensive damage was reported in Kalamata and Elaiochori. At least 20 people died and 330 were injured; a higher death toll was prevented because many residents of Kalamata attended a ferry line opening ceremony when the earthquake struck. Members of the Greek Army, police, and fire service were involved in rescuing people trapped in buildings. Survivors sought refuge at 30 campsites, and some moved to Athens.
