Study Notes

Effects of a Volcanic Eruption

Volcanic eruptions can change the earth's surface.
They can create new landforms, such as islands, like the Hawaiian Islands.

Positive Effects of Volcanic Eruptions

Ash deposited in the soil during an eruption can provide valuable nutrients for plants, making the soil fertile for agriculture.
Volcanic eruptions can create opportunities for generating geothermal energy, like in Tiwi, Albay.
The heat under the ground close to a volcano can be harnessed to produce renewable energy.

Negative Effects of Volcanic Eruptions

Ashfall can contaminate water sources and disrupt transportation.
Pyroclastic materials can damage a wide area.

What to Do in Case of an Eruption

Before a Volcanic Eruption

Stay informed about official warnings and updates.
Create a family emergency plan, including meeting points, communication methods, and a designated emergency kit.
Prepare an emergency kit with essential items like food, water, first aid supplies, flashlights, and batteries.
Familiarize yourself with evacuation routes and practice evacuation drills with your family.
