Taftan (volcano) published in 1897 indicated the absence of very fresh lava flows but the authors inferred from the fresh ash that volcanic activity had occurred during the present geological epoch. That the name "Taftan" may be derived from an ancient Iranian word "taft" for "semi solid liquid material" could indicate that effusive activity was witnessed by the people of that time period around the volcano. Eruptions are recorded in 1902, 1970 and 1993. A report of smoke emission in 1877 may have confused clouds for volcanic activity. In 1914, the volcano was described to be "belching out clouds of smoke", although
Volcano tectonic earthquake Volcano tectonic earthquake A volcano tectonic earthquake is an earthquake induced by the movement (injection or withdrawal) of magma. The movement results in pressure changes in the rock around where the magma has experienced stress. At some point, the rock may break or move. The earthquakes may also be related to dike intrusion and may occur as earthquake swarms. An example is the 2007–2008 Nazko earthquake swarm in central British Columbia, Canada. Other types of seismic activity related to volcanoes and their eruptions are long period seismic waves, which are from sudden sporadic movement of magma, which is blocked from
