instruments used
Shield Volcanoes
including
Volcanoes
-They are formed by fissures and hot spots
-They are wide, flat-top, non-explosive, and they ooze lava.
-lava erupts from them
-Hawaiian Islands and Iceland are examples of shield volcanoes.
Composite Volcano
Mt.St. Helens in Skamania County, Washington
Cinder Cone Volcano
-forms by convergent boundaries, and it forms from one middle vent
-they are small, very explosive, one vent, thick magma, and gas shatters rock and blows out ciinders
-thick magma, cinders, and lava oozes from the bottom
-Eldfell, Iceland and Paracuntin, Mexico are examples of cinder cone volcanoes
Mauna Loa (island in Hawaii)
Tiltmeter
measures extremely subtle changes in a volcano’s slope
Seismic Monitors
measures the increase of earthquakes in the process of the volcano erupting

they take pictures of the heat emitted by volcanoes

-erupted on August 24, 79 AD
-it is a composite volcano
-over 10,000 people died

Mt.St.Helens
-located in Skamania County, Washington
-erupted on May 18, 1980
-it is a composite volcano
-57 people died
The Toutle River was flooded by melting snow and ice from the mountain. About 12 million board feet of stockpiled lumber were swept in the river.
