Oh my god! There is a volcanic eruption!
But what is a volcano and volcanic eruption?
What is a volcanic eruption?
A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. When pressure builds up, eruptions occur. Gases and rock shoot up through the opening and spill over or fill the air with lava fragments. Eruptions can cause lateral blasts, lava flows, hot ash flows, mudslides, avalanches, falling ash and floods. Volcano eruptions have been known to knock down entire forests. An erupting volcano can trigger tsunamis, flash floods, earthquakes, mudflows and rockfalls.
But how are volcanoes formed?
Oh, I know!
Volcanoes are formed when magma from within the Earth's upper mantle works its way to the surface. At the surface, it erupts to form lava flows and ash deposits. Over time as the volcano continues to erupt, it will get bigger and bigger.
The Earth's crust is made up of huge slabs called plates, which fit together like a jigsaw puzzle. These plates sometimes move. The friction causes earthquakes and volcanic eruptions near the edges of the plates. The theory that explains this process is called plate tectonics.

How can we save ourselves?
If a lava flow is headed toward you Leave the area immediately. If you are warned to evacuate because an eruption is imminent, evacuate. If you can drive rather than walk, use your vehicle to evacuate. When driving keep doors and windows closed, drive across the path of danger if you can or away from the danger if you can not, and watch for unusual hazards in the road. If you are indoors Close all windows, doors, and fireplace or woodstove dampers. Turn off all fans and heating and air conditioning systems. Bring pets and livestock into closed shelters.
If you are outdoors Seek shelter indoors. If caught in a rockfall, roll into a ball to protect your head. If near a stream or river, be aware of rising water and possible mudflows in low-lying areas. Move up-slope as quickly as possible. Seek care for burns right away. Immediate care can be life saving. If your eyes, nose, and throat become irritated from volcanic gases and fumes, move away from the area immediately. Your symptoms should go away when you are no longer in contact with the gases or fumes. If the symptoms continue, consult your doctor.
