Volcano is a mountain which has been formed by accumulation of lava eruptions or volcanic ash. The eruption happens when the pressure of gasses and molten rocks rises. Eruption can occur gradually or explosively. Lava flow, toxic gases, throwing ash and stones and the destruction of surrounding areas also happen along with lava eruption.
Slow flow of lava may hardly threaten lives because these currents move very slowly. Therefore there is enough time for people to escape. However, the flow of lava may be followed by important financial and environmental damages. The immediate momentum of lava may destroy buildings and installations. It may block the roads. Its heat may also destroy trees and crops.
Actions before lava eruption
- To complete the set of specific equipment required for an emergency, provide a pair of safety glasses and disposable respiratory masks for each member of your family.
- If you live close to a volcano, active or inactive, be prepared to escape in emergencies.
Actions during lava eruption
- To comply with the orders of local authorities, leave the area immediately to avoid the risks of severe explosions, rocks and ash thrown out, lava flows and the formation and accumulation of hot gases.
- Quickly find a shelter.
- Get away from the valleys and the lower areas around the river.
- Don’t forget to help the people in need of help especially children, elderly, and disabled ones.
- Be careful of lava flow because it can move faster than you can walk or run. So be careful of lava flow before moving from one track.
- Listen to the radio or TV for the latest emergency information.
- Avoid contact even with small amounts of ash if you have shortness of breath.
- Wear sleeved shirt and long pants.
- Wear safety and ordinary glasses instead of contact lenses.
- To breathe in an atmosphere filled with dust and ash, use a mask or wet cloth.
- Close the doors and windows and turn off the air conditioning and heating systems.
- Avoid driving while the ash is falling unless you are forced to do that. In this case drive slowly with a speed of 30 km per hour.
Actions after lava eruption
- Listen to the radio or TV for the latest information.
- Stay at home as long as volcanic ash is suspended in the air unless there is a risk of roof collapse.
- Clean the ash on the surface, roof and the gutter of the building.
- Avoid turning the truck and motor cars on. Volcanic ash can result in engine failure and can cause damage to the parts of vehicle and consequently the vehicle breaks down.
