The 1988 Armenian earthquake, also known as the Spitak earthquake ( hy, Սպիտակի երկրաշարժ, ), occurred on December 7 at with a surface wave magnitude of 6.8 and a maximum MSK intensity of X (''Devastating''). The shock occurred in the northern region of

) which is vulnerable to large and destructive earthquakes and is part of a larger active seismic belt that stretches from the Alps to the Himalayas. Activity in the area is associated with tectonic plate boundary interaction and the source of the event was slip on a thrust fault just to the north of Spitak. The complex incident ruptured multiple faults, with a strike-slip event occurring shortly after the initiation of the mainshock. Between 25,000 and 50,000 were killed and up to 130,000 were injured. Seismologists thoroughly studied the effects of the Spitak event, including the mainshock and aftershock fault rupture mechanisms, and were on site setting up temporary seismometers before the end of 1988.

The relationship between the Soviet authorities and the Armenian society took a turn for the worse in March and the developments climaxed in November when a state of emergency was declared, along with a nighttime curfew, and a mass movement of up to 50,000 Armenians fleeing ethnic violence in events such as the Sumgait Pogrom arrived from Azerbaijan.

Many buildings did not hold up to the shaking of the earthquake and those that did collapse often lacked any survival space, but lack of effective medical care and poor planning also contributed to the substantial scope of the disaster.

. A team of earthquake and engineering experts from the United States spent a period of time in Armenia in December 1988 and January 1989. The group, including a structural engineer who specialized in seismic-resistant designs, agreed that building inadequacies were the primary reason why the strong (but not huge) earthquake was so damaging, although the freezing temperatures also played a role in the unusually high death toll. The earthquake death toll was by far the highest worldwide in the 1980s and third-highest worldwide in the period 1971–2003 (33 years). The engineers who scrutinized the damaged buildings and the rescue workers who had dismantled the buildings while extricating survivors ascribe both design shortcomings and improper construction methods for the failure of the buildings. The Soviets had modified their construction style to accommodate the known

may have also contributed to the fluctuation in damage. In late December the last of the survivors that were able to be extricated were pulled from the fallen buildings, rescue operations ceased, and the cleanup began, beginning with the destruction of buildings that were too heavily damaged to be repaired. Six friends were in the basement of a nine-story building relocating barrels when it came down around them on December 7. Their injuries were minor, but one person did suffer a broken arm. They supposedly sustained themselves on the food supplies—fruit salad, pickles, and smoked ham—that were available in the basement for 35 days before their rescue in January, but this turned out to be a hoax.


Aftershocks

The area where Armenia lies is of interest to seismologists and geologists because of the relatively early stage of

occurring there and because the earthquake's strong aftershock sequence and significant surface faulting presented scientists with an environment to study reverse faulting. Twelve days after the mainshock a French-Soviet team installed a temporary seismic network in the epicentral area to record aftershock activity (a separate expedition from the United States also visited the site). The initial portion of work included nearly a full week setting up the seismometers and optimizing their operation and, with that complete, two full weeks of continuous operation was then completed with twenty six seismometers covering an area over 1,500 km2. The final stage concluded with seven weeks (through the end of February 1989) of continued monitoring with a reduced capacity of twenty units. The instrumentation included ten smoked paper analog

Liquefaction

Buildings and other structures were extensively damaged during the earthquake, but roadways and railways also experienced disturbances. Many case histories pertaining to

The first well-documented case of liquefaction in gravelly sands was in regard to the 1983 Borah Peak earthquake in the United States. Several investigations of that event took place in the 1980s and early 1990s and the primary conclusions were that a critical condition for liquefaction to occur in that type of soil was the presence of a low permeable crust that did not allow pore water pressures to subside and that the assessment method and associated

(trauma associated with building collapses), but were unable to get started for four days until the visas were available. With the hospitals destroyed and their limited knowledge of the care requirements, the Soviets were not well-equipped to deal with the cases of crush syndrome. Author and professor of geopolitics Pierre Verluise detailed in his 1995 book ''Armenia in Crisis: The 1988 Earthquake'', how a French doctor and director of a Leninakan hospital described that he had seen one hundred victims suffering from the syndrome each day during the first three days. In order to prevent kidney failure or death, the treatment requires prompt hospitalization, and, according to the doctor, the victims were not receiving adequate medication and dialysis and, as a result, most died before the arrival of the first foreign dialysis machines.


Rebuilding

In February 1989 one hundred construction workers were assembling temporary housing for themselves in Leninakan with a plan to start on the local population's housing by the end of the month, though schools and factories were also on the list of facilities to be rebuilt. Deputy chairman of a city building and architecture council said that updated

. Other officials decided that the town would be relocated several kilometers to the southwest. As of July 1989, about $500 million in donations had been delivered to the Armenians from 113 countries. Most of those funds went into the initial relief work and medical care plus the beginning portion of the rebuilding phase. Yuri S. Mkhitarian, an Armenian State Building Committee official, gave an updated damage report that included some of the outlying communities away from the population centers stating that 342 villages were damaged and another 58 were destroyed. The negative effect the earthquake had on the economy of Armenia was apparent. Mkhitarian said that 130 factories were destroyed and 170,000 people were out of work. Officials acknowledged that the work to complete the rebuilding may take up to five years or longer, a supposition that more than doubled Gorbachev's estimate of two years. At that time 20 projects had completed the planning process and some had been approved and construction started. In Leninakan, there was a need for 18 new hospitals, 12 of which could be funded with the assistance of the

, but foreign help would be required to build six additional facilities. Boris Karapetyan, director of earthquake studies at the Yerevan Polytechnical Institute, said of the difficult rebuilding process "Coordination is a major, major problem. This is a massive undertaking, and foreign involvement is both a necessary and a complicating factor. We need foreign assistance—and there is no doubt about that—but our friends do not know the local conditions and propose things that cannot or should not be built in an earthquake-prone region." The Soviets and an American group of architects each devised separate outlines for rebuilding the town of Spitak. Following an invitation by the Soviets for a critique of their plan, the American proposal was ultimately accepted as the way forward. The new plan would deviate from Soviet styles that were found to be rigid and outdated and would mirror characteristics of the local culture. For many years following World War II the Soviets practiced a methodical top-down approach to
