GEOLOGY

Detailed explanation-1: -It may create a thick layer of dust-like material on surfaces for miles around the original eruption. Unlike the ash produced by burning wood and other organic materials, volcanic ash can be dangerous. Its particles are very hard and usually have jagged edges.

Detailed explanation-2: -Mount Tambora ejected so much ash and aerosols into the atmosphere that the sky darkened and the Sun was blocked from view. The large particles spewed by the volcano fell to the ground nearby, covering towns with enough ash to collapse homes.

Detailed explanation-3: -If available, everyone should wear respiratory masks. If not available, a damp cloth held over the nose and mouth can help to filter out the ash. If you wear contact lenses, you should remove them. They can trap irritants against your eye or may react to the gases carried by the wind from the eruption.

Detailed explanation-4: -“The most effective respiratory protection for adults is to wear a well-fitting, industry-certified facemask such as an N95 mask (also called P2, FFP2 or DS2 in different parts of the world). The certification will be printed on the mask. Such masks are usually disposable.

Detailed explanation-5: -Volcanic ash is formed during explosive volcanic eruptions. Explosive eruptions occur when gases dissolved in molten rock (magma) expand and escape violently into the air, and also when water is heated by magma and abruptly flashes into steam. The force of the escaping gas violently shatters solid rocks.
