Tor Zawar is a fissure vent volcano in central Pakistan and the only recent volcano in Pakistan and South Asia. Its first, and so far only, eruption occurred in January 2010.
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 region near the village of Wham.
2010 eruption
An eruption in the region on 29 January 29, 2010 shocked the world's volcanological society, as no previous volcanic activity had ever taken place there before. 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.[1]
