vOLCANOES AND SOCIETY NOTES
WHERE ARE MOST OF EARTH'S VOLCANOES?
- Pacific Ring of Fire
- 75% of Earth's active and dormant volcanoes
- Volcanism is mostly focused at plate margins OR hot spots
- Pacific Ring of Fire stretches along East Asia, across Alaskan Islands, and along the coast of the Americans
- US contains only about 10% of all active volcanoes
- There are thought to be about 600 million people living close enough to active volcanoes to be affected when they erupt.
- Causalities from volcanic eruptions have been modest (around 300,000 in the last 200 years) compared to other hazards, but socioeconomic losses and disruption can be considerable
- The modern globalized world is vulnerable to very large volcanic events, making the study of return periods, environmental effects, and consequences a key goal of volcanology
- Flooding
- Due to rise in water level/glacial melting
- Destroys structures, obstructs traffic (air traffic impeded by ash)
- Global Climate Impact
- Sulfur clouds make Earth's atmosphere more reflective, cooling the planet
- Interferes with crop production
- Property Damage
- EX: Insurance is not widely available and is costly
- Around the world, disasters occur each day. Sometimes the impacts are felt locally, other times, the event reaches across state and national boundaries
- Globally the number of natural disasters has increased 4X during the past 3 decades -- from 120/year during the 1980s to roughly 500/year now. These disasters exert a uneven impact on the worlds poorest and most vulnerable individuals.
Constructive and destructive vOLCANOES
1st photo is constructive volcano because it is creating an island
2nd photo is creating new fertile soil to plant on
3rd photo is creating a crater lake

1st photo is a house that was hit by lava
2nd photo is the tephra flying out of the vent
3rd photo is the ash making it harder for the people to breath

5 safety tips for surviving earthquakes
1. A first aid kit that contains pain relievers, allergy medication, disinfectants, gauze, gloves, bandages and a thermometer
2. A three-day supply of bottled water, you should have one gallon per person, per day. Change this supply every six months.
3. A supply of canned and prepackaged dry food; restock this food every year, and don't forget a can opener
4. A wrench or other tool to turn off gas and water
5. Copies of everyone's personal IDs and photos of children and pets who don't have IDs

5 Safety tips for surviving tsunamis
1. Learn about your possible danger in the area that you live in
2. Watch for animals leaving the area or behaving abnormally, such as trying to seek human shelter or grouping together in ways they would not normally do
3. Move inland, and to high ground
4. Develop an evacuation plan
5. Grab something that's floating and go with the current.
