10 VOLCANIC HAZARDS SHOWN IN AN ERUPTING VOLCANO
Explanation:
1. ERUPTION COLUMN- Is a cloud of super heated ash and tephra suspended in gases emitted during an explosive volcanic eruption.
2. LAVA FLOWS- Non-fragmented magma ( a mixture of molten or semi-molten rock).
3. LAVA DOME- Is a circular mound-shaped protrusion resulting from the slow extrusion of vircous lava from the volcano.
4. MAGMA-Is found beneath the surface of the earth and evidence of magmatism has also been discovered on other terrestrial planets and some natural sateclites
5. Fumaroles-Are openings in the earth surface the emitted steam and volcanic gases such as sulfur dioxide and carbon dioxide.
6. PYROCLASTIC FLOW-Is a dense fast moving flow of solidified lava pieces,volcanic ash and hot gases.
7. LANDSLIDE(DEBRIS AVALANCHE)-Is the sudden catastrophic collapse (landslide) from an unstable side of a volcano.
8.GROUNDWATER-Is the water present beneath earth surface in soil pore spaces and in the fractures of rock formations.
9. LAHAR/MUD OR DEBRIS FLOW-Are volcanic mudflows and they do not have to come directly from volcanic activity.
10. BOMBS-Is a mass of molten rock larger than 64mm in diameter formed when a volcano ejects viscous fragment of lava during an eruption.
