Answer 2

Answer:

Volcanism is the phenomenon of eruption of molten rock onto the surface of the Earth or a solid-surface planet or moon, where lava, pyroclastics and volcanic gases erupt through a break in the surface called a vent.

Take temporary shelter from volcanic ash where you are if you have enough supplies. Cover ventilation openings and seal doors and windows. If outside, protect yourself from falling ash that can irritate skin and injure breathing passages, eyes, and open wounds. Use a well-fitting, certified face mask such as an N95.
