The frequency of shield volcano eruptions can vary widely depending on the specific volcano and its geological context. Some shield volcanoes, like Mauna Loa in Hawaii, can erupt frequently, with eruptions occurring every few years or even months. Others may remain dormant for centuries before erupting again. Overall, the eruption patterns are influenced by the movement of magma and tectonic activity in the region.

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 shield volcanoes erupt?
Shield volcanoes typically have relatively gentle eruptions and can erupt frequently, but the frequency varies based on the specific volcano and its geological context. Some shield volcanoes, like Mauna Loa in Hawaii, can erupt every few years or even multiple times a year. Others may have longer periods of dormancy between eruptions, lasting decades or centuries. Overall, their eruptions tend to be less explosive compared to other types of volcanoes.
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 are the three type of volcanoes how do they erupt and from?
The three main types of volcanoes are shield, stratovolcanoes (or composite volcanoes), and cinder cone volcanoes. Shield volcanoes, like Mauna Loa, have gentle slopes and erupt primarily through the effusion of low-viscosity basalt lava, resulting in broad, expansive landforms. Stratovolcanoes, such as Mount St. Helens, exhibit steep profiles and erupt explosively due to more viscous magma, often resulting in pyroclastic flows and ash clouds. Cinder cone volcanoes are the smallest and erupt explosively, spewing out ash and small lava fragments that accumulate around the vent to form a steep, conical hill.
How often do dormant volcanoes erupt'?
Never.
Will a shield volcano erupt?
Yes. If it doesn't erupt and never has erupted then it is not a volcano.
When did the first Shield Volcano Erupt?
bi lava
What volcanoes erupt gently?
Shield volcanoes erupt least violently cinder cone most violently and compost can erupt either way.
When did a shield volcano erupt?
because movement of tectonic plates
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.
What lava does a shield volcano erupt poehoehoe or AA?
Usually both.
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 is called in a volcanoes that is not erupting?
You've got to be kidding me. A volcano that erupts often is called a cinder cone volcano, a volcano that does not erupt at all is called a shield volcano, and a volcano that can erupt but doesn't is a composite volcano. Here is the chart. Cinder cone: eruption Shield: dead Composite: sleep Hope you use my answer wisely. NOOBS!
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.
When volcanoes erupt will they ever erupt again?
Yes, they often erupt again.
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.
How often does a volcano explode?
It depends, a volcano can erupt once and never erupt again. Or, a volcano can erupt multiple times a day.
