Just a bit of history to give you an idea what its like living on several active volcano's.
1. How many volcanoes are there on the Big Island? Which ones are extinct, dormant, or active?
Five volcanoes make up the island of Hawai`i: Kohala, Mauna Kea, Hualalai, Mauna Loa, and Kilauea.
Volcanoes that will never erupt again are considered extinct. Dormant volcanoes have not erupted in historic time (the last 200 years in Hawai`i) but probably will erupt again. Active volcanoes have erupted in historical time (the last 200 years in Hawai`i).
Kohala, the oldest volcano on this island, last erupted about 60,000 years ago and is considered extinct.
Mauna Kea last erupted 3,600 years ago and is dormant.
Hualalai, Mauna Loa, and Kilauea are active.
Hualalai erupted seven times in the last 2,100 years. The only historic eruptions were in 1800 and 1801. Mauna Loa last erupted in 1984 and sent flows towards Hilo. Kilauea has been erupting since 1983. 32 years non stop.
Loihi, a submarine volcano, is 15 miles (24 km) southeast of the island and 3,178 feet (969 m) below sea level. Loihi will probably not reach sea level before 250,000 years or more. Seismicity, geothermal vents, and fresh lava indicate Loihi is active.
So when someone says the volcano is erupting, we stop and think to ourselves, its always erupting.
And sometimes, just like that
A volcano can blow its' stack.
Remember Krakatoa
Remember Pompeii - Great Volcano, the movie sucked.
Remember Mt. St. Helens
Remember all those fifties caveman movies with a volcano in the back ground that blows in the end of the movie.
Those Who Do Not Remember May Well Get Burned.
And YOU may not even notice, pffft, faster than a struck match igniting.
A pyroclastic flow (also known scientifically as a pyroclastic density current) is a fast-moving current of hot gas and rock (collectively known as tephra), which reaches speeds moving away from a volcano of up to 700 km/h (450 mph). The gas can reach temperatures of about 1,000 °C (1,830 °F).
Volcanoes erupt because that's what they do. Yup!
