  • What is the Lava? About LavasTowns destroyed, damaged by lava
  • Lava is molten rocks that come out during the volcanic eruption. The volcano is liquid when it first exits from its mouth and its temperature is between 700 ° C and 1200 ° C (1300 ° F and 2200 ° F).


  • Although the lava is not very fluid (about 100,000 times more than the fluidity resistance of the water), it can run long distances until it cools and solidifies. The lavas may differ according to the flow types. There are two types of lavas; Aa and pahoehoe. Aa is very dense and forms conical volcanoes. Pahoehoe (pronounced “pahoyhoy“) is very fluid and forms flat volcanoes according to AA. The names Aa and pahoehoe were first used by the Hawaiian natives.
