The 2000 Baku earthquake occurred on November 25 at 22:09 (18:09

Dagestan
.

Tectonic setting

Baku lies on the

Absheron peninsula close to the northern edge of the broad and complex zone of deformation caused by the continuing collision between the Arabian Plate and the Eurasian Plate. There are two main active seismic zones on the Absheron peninsula. The northern zone is part of the North Caucasus thrust belt that continues to the east along the Apsheron Sill, which is interpreted to be a zone of active subduction. Earthquakes recorded in the northern zone are mainly deep reverse or shallow normal in type.[3] The southern zone is interpreted to be a continuation of the Greater Caucasus thrust. Earthquakes in this area are mainly reverse or right lateral strike-slip in type.[4]

Earthquake

The earthquake consisted of two closely spaced events 90 seconds apart. The first event had an oblique reverse fault mechanism on a steeply-dipping fault trending northwest–southeast, while the second was pure reverse in type on a moderately-dipping reverse fault trending west-northwest–east-southeast. Within the uncertainties, the two events occurred at the same depth, at about 40 km.[5]

Damage

According to the Azerbaijani government, 26 people died as a primary result, but only three people in collapsing buildings. A total of 412 people were either hospitalised or sought medical assistance. President

. Despite affecting northeastern coastline of Azerbaijan no damage to the offshore oil exploration infrastructure has been reported.

Many phone lines were down and the electricity was out in much of the city. Due to anxiety caused by possible fires the natural gas supply was reduced to 80%. Baku and Sumgait residents spent the rest of the night on the street. After the disaster

seismologists
have banned the construction of buildings with over nine floors.

On the same day the earthquake in Saratov, Russia caused by tectonic changes in the Volga region after the Baku earthquake took place.[6]

Aftermath

Following the presidential decree of November 28, 2000, the State Emergency Commission was provided with an amount of ca. US$5,5 million in order to deal with the consequences of the earthquake. The SEC dispatched assessment teams to the affected areas. In Baku, as of November 27, 19 families have been evacuated from three severely damaged houses. Schools have been temporarily closed.

The

IFRC
launched an emergency appeal for international assistance amounting to US$590,000.
