WHAT IS A VOLCANO?

A natural opening in the surface of the Earth where molten rocks,hot gases,smoke and ash are ejected.

VOLCANIC ERUPTION Volcanic eruptions happen when lava and gas are discharged from a volcanic vent. A volcanic eruption occurs when molten rock, ash and steam pour through a vent in the earth's crust

Difference between active

volcano and inactive volcano

Active volcano is a volcano that has erupted within the last 600 years and are documented by man or those that erupted 10,000 years ago based on analyses of datable materials while inactive volcano is a volcano that

shows no record of eruption physical form is being changed by agents of

weathering and erosion via formation of deep and long guillies.

THINGS TO REMEMBER

BEFORE, AFTER, DURING

VOLCANIC ERUPTION

VOLCANIC ERUPTION…

BEFORE VOLCANIC ERUPTION

1. Know beforehand where the active volcanoes are in

your area.

2. Put together an emergency supply kit.

3. Have the necessary communication devices ready.

4. Be aware of what your local disaster sirens sound like. 

5. If you live near a known volcano, active or dormant, learn about your community warning systems and

emergency plans, and be ready to evacuate at a moment's notice.

6. Put goggles and disposable breathing masks for each family member in your  disaster supply

kit.

During Volcanic Eruption

1. Listen to a battery-operated radio or

television for the latest emergency information.

2. Follow the evacuation order

issued by authorities.3. Avoid areas

downwind and river valleys downstream of

the volcano.

If caught indoors:

4. Close all windows, doors,

and dampers

5. Put all machinery inside a garage or barn.

If trapped outdoors:6. Seek shelter

indoors. 7. If caught in a rockfall, roll into a ball to protect your

head.

8. If caught near a stream, be aware of mudflows. Move up slope, especially if you hear the roar of a mudflow.

Protect yourself during ashfall:

9. Wear long-sleeved shirts and long pants.

10. Use goggles to protect your eyes.

11. Use a dust mask or hold a damp cloth over your face to help

breathing.12. Keep car or truck engines off.

Remember: Stay out of the area defined as a restricted zone by government officials. Effects of a volcanic eruption can be experienced many miles from a volcano. Mudflows and flash flooding, wildland fires, and even deadly hot ashflow can reach you even if you cannot see the volcano during an eruption. Avoid river valleys and low lying areas. Trying to watch an erupting volcano up close is a deadly idea.

After Volcanic Eruption

1.If possible, stay away from

volcanic ashfall areas.

When outside:2. Cover your mouth and nose. Volcanic

ash can irritate your respiratory system.

3. Wear goggles to protect your eyes.

4. Keep skin covered to avoid irritation from contact with ash.

5. Clear roofs of ashfall. Ashfall is very heavy and can cause buildings to collapse. Exercise great caution when

working on a roof.

6. Avoid driving in heavy ashfall. Driving will stir up more ash that

can clog engines and stall vehicles.

7. If you have a respiratory ailment, avoid contact with any

amount of ash. Stay indoors until local health officials advise it is

safe to go outside.

Remember to help your neighbors who may

require special assistance — infants, elderly people, and

people with disabilities.
