» When a volcano erupts, gas, liquid and solid materials are spewed out. Steam or water vapor makes up 50% of the gas materials. The rest are carbon monoxide, carbon dioxide, hydrogen sulfate, sulfur dioxide, hydrochloric acid, methane and ammonium chloride. Most of these gases are poisonous when present in large amounts and can affect our air which can cause air pollution
Solid products are rocks of hardened lava and ashes. When rain accompanies eruption, the poisonous gases in the air are carried by water down to the soil in a form of mud flow or lahar.
Land formed from the erupted materials are the greatest resource from a volcanic eruptions. Most fertile soil near the volcano supports the lush vegetation of the place.
Geothermal energy is an alternative source of electricity. People living near volcanic regions use underground steam as the source of energy. Steam can be generated to power turbines that can spin generators to produce electricity. The geothermal power plant in Tiwi, Albay generates electricity in this manner.
Ecologists hypothesized that volcanic activities play a vital role in reducing global temperature and thereby reducing the overall warming trend. However, the cooling effects provided by these volcanic activities are only temporary.
What is Volcanic?
As we all know, a volcano is a land form that has crater or vent where the magma or molten rock, pieces of hot solid rock, and hot gases are formed inside the Earth when the upper crust or the lower crust melts.
When that magma or molten rocks burst out through its crater, we call it lava and that happens during a Volcanic Eruption-one of the natural disasters that people are afraid to encounter.
Poisonous gases such as carbon dioxide, carbon monoxide, and sulfur dioxide can travel down a volcano and asphyxiate (suffocating) wildlife and humans.
Lahars are volcanic mudflows. Lahars are very dangerous because they do not require a volcanic eruption yet can travel hundreds of miles. All that is required is loose pyroclastic material on the volcano that mixes with precipitation.
What to do before volcanic eruption?
Each one should be aware of the dangers that volcanic eruptions pose to lives and be prepared to face whatever circumstances the eruption may bring.
Prepare all the necessary things to bring once evacuation is needed.
Store as much food, water, light sources and batteries that are very useful in case of emergency.
Prepare masks to cover nose and mouth for the ash falls of the volcano.
Safety of the kids first before anything else.
What to do during volcanic eruptions:
Avoid low-lying places because lava flows, and mud flows are more likely to pass here.
Seek cover in case of ash falls and rock falls and use masks to cover your nose and mouth and to avoid breathing in the ashes.
If inside the house, close all doors and windows to avoid letting in the ashes.
Always stay indoors and watch for your kids, they might be tempted to go out.
Stay in the evacuation center and wait for further instructions and do not leave until said so.
What to do after volcanic eruptions:
Go back to your house but leave your kids with someone who can take care of them while you check your house.
When in your house, clean everything and check if there's damages incurred. Use masks when cleaning.
Wait for further announcements related to volcano activities.
Make sure that your house is still safe for all of you.
