Have you heard about the #mud #volcanoes? #azerbaijan #mudvolcano

A post shared by Lingofacts (@lingofacts) on

Azerbaijan has more mud volcanoes than any other country on earth – more than 400. When its volcanoes erupt, the flames shoot up to a kilometre in the air, and when dormant they bubble and pop with noxious gases.

Every 20 years or so, one of these mud/gas volcanoes will ignite deep below the surface and create a massive explosion. While generally not dangerous to people, as they are far outside of most city centers, it is believed that six shepherds and over 2,000 sheep were killed by a mud volcano in Bozdagh, Azerbaijan.
