SUPERVOLCANO
It's ready to blow!
Classification
Classified 1-8
8 being the worst eruption
1 being the most subtle
Super volcanoes= 8
The last level 8 eruption was around 26,500 years ago!
Locations of the largest known supervolcanos
- Yellowstone Volcano, USA
- Long Valley Volcano, USA
- Lake Toba Volcano, Indonesia
- Aira Caldera, Japan
- Mount Tambora, Indonesia
All are near the Ring of Fire along the Pacific Coastline.
How do they form/erupt?
- Along faults
- Buildup in pressure underground
- Earthquakes can cause eruptions
- Nuclear testing
- Over time
The colossal consequences of supervolcanoes - Alex Gendler
Preparations
- Move to the east
- Always have a supply stockpile
- Respirators
- An indoor safehouse
Example: Mount St. Helens (Not Super)
- Caused by earthquake
- Moved 4 million cubic yards of rock and ash
- 9 hour eruption
- 57 people died
- Categorey 5 eruption
Example: Mount Tambora
- Erupted in 1815
- Level 7 eruption
- Killed over 71,000 people
- Killed plant life in the area
- Lowered the global temperature for the year
Effects of a Super Volcanic Eruption
- No Summer/Nuclear Winter
- Blocked Sun
- Human Death
- Sulfuric Rain
- Poor Air Quality
- Ash Everywhere!
Preparations
- Safe indoor Shelter
- Food and Water
- Respiration
- Battery Powered Devices
It would be hard to prepare for, due to the widespread devastation.
What are the odds?
- Some say the Yellowstone Volcano can blow anytime.
- The Yellowstone Volcano is overdue to erupt.
- Some scientists say that it won't erupt again.
- Chance of eruption in the next 1,000 years is small
