Volcanoes in the Cascade Range erupt on average every 100 years. However, the frequency of eruptions varies between different volcanoes, with some erupting more frequently than others. It's important to note that eruptions can also occur in clusters or with long periods of dormancy.
Never.
they arupt 2 a year
They don't. Few, if any volcanoes in the world do. The volcanoes, especially at subduction zones, will often go dormant for years and even centuries without erupting.
The frequency of volcanic eruptions varies depending on the volcano. Some volcanoes erupt frequently, while others may remain dormant for hundreds or thousands of years. It is difficult to predict exactly how many times a volcano will erupt in the future.
Volcanoes supplied by subduction zones usually erupt due to buildup of pressure of these gases. This lava tends to erupt explosively as solid pieces of ash, cinders, bombs, etc. often filled with gas bubbles. Volcanoes supplied by deep mantle hotspots have almost no gas in their lava and erupt due to buildup of magma rising from the hotspot. This lava tends to erupt quietly as a fluid.
Yes, they often erupt again.
There are no volcanoes in the Grand Canyon.
Never.
every 2 years
Yes. Composite volcanoes often produce violent eruptions.
they arupt 2 a year
As many as it wants. Some volcanoes erupt often, some infrequently
At their early stage mostly during the youthful age.
Often volcanoes erupt throwing molten rock which is glowing hot if they are not just spouting smoke and ash.
Volcanoes eurpt more often in Mount St. Helen located in Washington in the U.S
They don't. Few, if any volcanoes in the world do. The volcanoes, especially at subduction zones, will often go dormant for years and even centuries without erupting.
Active volcanoes are those which are liable to erupt or have shown frequent eruptions within recent history.They are ones that still erupt at (irregular) intervals, often gently emitting gases and steam during their quiescent spells.
