Tor Zawar is a fissure vent volcano in central Pakistan. The only recent volcano in Pakistan and the Indian Sub-Continent, 2 eruptions occurred on from 27 January to 3 March 2010 and January 2011.
Morphololgy
Tor Zawar is a group of closely spaced fissure vents on a non-volcanic mountain in a tectonically active region between the Bibai and Gogai thrust faults (Global Volcanism Program) which is in the Ziarat reigon near the village of Wham.
2010 eruption
An eruption in the region shocked the worlds volcanological society, as no previous volcanic activity had ever taken place there before, the eruption took place on January 29, 2010. A local scientist reported that the fissures opened, then emitted gases for a little while before the eruption began. The eruption produced a small spatter cone and a lava flow that only travelled 8.2 metres, and caused some minor damage. The eruption was of trachybasalt and basaltic-andesite in composition.
The eruption was preceded by a 60 km deep earthquake on 27 January. The calculated source depth of the lava is consistent with an origin at this depth in the asthenosphere.
2011 eruption
A small eruption took place in January 2011 from another location, 300 M away from the original site.
