Witness for eruptions?
Eruptions of mud volcanoes in Azerbaijan have been recorded since 1810. For the last two hundred years, in 93 mud volcanoes there have been recorded 387 eruptions. Some volcanoes erupted more than 20 times for this period. They are Lockbatan volcano in Absheron and Shikhzarli volcano in Gobustan. There exists no information about eruptions of other 100 volcanoes, though it is obvious that they often erupted in geological past as well.
