Neftegorsk Russia 1995 (CAR)
On Saturday 27th May 1995, at 23:03 local time, an earthquake of moment magnitude 7.0 and focal depth of 11 km struck near the town of Neftegorsk on Sakhalin Island, Russia.
The earthquake's source coincided with the Piltoun fault and produced a 40 km long surface fault rupture. The fault was mainly a right-lateral slip with a maximum slip amplitude of 8 m.
The isolated town of Neftegorsk had a population of around 3180 people and was an urban-type settlement for the workers of nearby oil fields and their families. Housing was provided in the form of 25 state built mid-rise apartment buildings, surrounded by few other buildings for public services.
The earthquake caused the total collapse of 17 five-story reinforced concrete apartment buildings, with 80 units each, as well as four smaller apartment buildings with 16 units each, the town hall, the administration building, a heat generating building, and a number of shops.
Most of the collapsed buildings had been built in the 1960’s with prefabricated concrete panels having little regard for earthquake resistance.
The next morning with the light of day a scene of total devastation emerged, as only 4 three-storeyed brick masonry buildings and the part of the school building were still standing.
Nearly 76% of the town’s population lived in the collapsed buildings. Frantic search and rescue operations took place, first by the few survivors and the next days by state authorities. It was possible to pull out alive from the rubble 405 people, 40 of which died later in the hospitals. In the end 2032 lives (64% of the town’s population) were lost.
