Pyroclasic materials from shield volcanoes?
Pyroclastic flows don't come from shield volcanoes. They come from cinder cone and sometimes composite volcanoes. Shield volcanoes only erupt runny lava.
Why do shield volcanoes erupt frequently but rarely cause human disasters?
Shield volcanoes erupt lava with a low silica content. There are less dissolved gases and a lower viscocity fluid, so less gas is produced and it takes less pressure to erupt.
How often do dormant volcanoes erupt'?
Never.
What type of lava comes from what volcano?
Shield volcanoes will erupt basaltic lava. Cinder cones erupt basaltic lava or basaltic andesite lava. Stratovolcanoes often erupt andesite lava, but may erupt basaltic or rhyolitic lava and all intermediate types as well.
Does a shield volcano have runny lava?
In volcanoes that have lower amounts of volcanic gases in the magma. A good example is the volcanoes in the Hawaiian islands. Volcanoes with more gases in the magma tend to erupt explosively (Mt. St. Helens, Vesuvius) and have a thicker, slower moving lava.
What volcanoes erupt gently?
Shield volcanoes erupt least violently cinder cone most violently and compost can erupt either way.

When volcanoes erupt will they ever erupt again?
Yes, they often erupt again.
Why do shield volcanoes erupt frequently but rarely cause human disasters?
Shield volcanoes erupt lava with a low silica content. There are less dissolved gases and a lower viscocity fluid, so less gas is produced and it takes less pressure to erupt.
Do the volcanoes erupt often in the Grand Canyon?
There are no volcanoes in the Grand Canyon.
How often do dormant volcanoes erupt'?
Never.
What is the difference between a composite and shield a Volcano?
Shield Volcanoes erupt less violently and flows further then composite volcanoes. A composite volcano erupts more violently.
What type of lava comes from what volcano?
Shield volcanoes will erupt basaltic lava. Cinder cones erupt basaltic lava or basaltic andesite lava. Stratovolcanoes often erupt andesite lava, but may erupt basaltic or rhyolitic lava and all intermediate types as well.
What type of explosion does a shield volcano have?
Generally shield volcanoes do not explode. They erupt in a non-explosive fashion, fountaining or oozing lava.
How are shield volcanoes and cinder cone volcanoes somewhat same?
Both erupt basaltic lava, which has a low silica content and a high temperature.
How often do the volcanoes in Nicaragua erupt?
every 2 years
Do composite volcanoes erupt violently?
Yes. Composite volcanoes often produce violent eruptions.
