The 7.0 Mw  Neftegorsk earthquake shakes the former Russian settlement of Neftegorsk with a maximum Mercalli intensity of IX (Violent). Total damage was $64.1–300 million, with 1,989 deaths and 750 injured. The settlement was not rebuilt.

The 1995 Neftegorsk earthquake occurred on 28 May at 01:03 local time in northern Sakhalin Island in the Russian Far East. It was the most destructive earthquake known within the modern borders of Russia, with a magnitude of M_w7.1 and maximum Mercalli intensity of IX (Violent) that devastated the town of Neftegorsk. Many buildings collapsed, and 1,989 of its 3,977 citizens were killed, with another 750 injured. Infrastructure was catastrophically damaged, leading to Neftegorsk becoming a ghost town. Surface effects from the earthquake were widespread, with many geological features changing or developing. Due to its location along a poorly understood plate boundary, the earthquake received considerable attention from scientists, and dozens of research papers have been written about it.

Neftegorsk, formerly Vostok before 1970, is a ghost town in Sakhalin Oblast, Russia.

The Modified Mercalli intensity scale measures the effects of an earthquake at a given location. This is in contrast with the seismic magnitude usually reported for an earthquake.

The United States dollar is the official currency of the United States and several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color.
