- There is a difference between Hawaii's magma and magma from other parts of the world. Hawaiian magma has less dissolved gases than other magma. It also has little silica and lots of ferrous oxide. Hawaiian lava turns into basalt and the lava is very much like liquid.
-All the lava from Kilauea can pave a road 3 times around the earth. There have been 25 historic eruptions. It has caused over 100 deaths. Lava less than 1000 yrs old covers 90% of Kilauea.
-Ancient Hawaiians buried dead in lava tubes.
-Pyroclastic flow is the most deadly part of a volcano. A Pyroclastic flow is super hot gas, ash, rock, and debris. (Ouch!)
- There are 600 active volcanoes on the Earth today.
- Magma comes from the Greek word meaning "dough".
- The main island of Hawaii, an active volcano, is taller than Mt. Everest, if you measure from the ocean floor.
- The opening at the top of a volcano is called a caldera, from the Spanish word meaning "pot".
- In 1935, the U.S. Air Force bombed a lava flow headed for the Hawaiian city of Hilo. The flow slowed and stopped, but nobody has been able to prove that the bombs were responsible.
- During volcanic eruptions, lightning storms are common.
- There are no active volcanoes in Australia.
