From what I remember, Krakatoa was where tectonic plates moved, which triggered a volcanic eruption and I'm pretty sure a tsunami/tidal wave. Hope that helps! I'm sure there are more instances of this though, this is just one example.
Active volcanoes are currently erupting, have erupted in the past 10,000 years, or have the potential to erupt in the future. Inactive volcanoes, also known as dormant, are currently not erupting but have the potential to erupt again in the future.
Extinct volcanoes will never erupt again... I am not sure what stage but this is the best info I can give you.
Many volcanoes erupt in Europe. The most high profile one in 2010 has been Eyjafjallajökull in Iceland.
They have been created during the formation of the earth millions and even billions of years ago. Earthquakes and tectonic plate shifts may help form volcanoes, and may even erupt them.
There have not been any eruptions though rare earthquakes have occurred before.
Continental Drift
People have been fascinated by volcanoes for thousands of years. Volcanologists hope to be able to predict when volcanoes will erupt and save lives.
In most cases, neither. Most earthquakes are the result of plate tectonics and most volcanoes form from plate tectonics as well, but one does not usually cause the other. However, volcanoes can and do cause earthquakes, espcially if they are getting ready to erupt. On rarer occasions, earthquakes have been suspected of triggering volcanic eruptions.
No they are not, relatively few earthquakes have ever been recorded in Australia as it is a very stable continent with no active volcanoes and few if no earthquakes.
Earth's craters have been created by Meteorites and Volcanoes.
True. All volcanoes have the potential to erupt again, even if they have been dormant for long periods. Dormant volcanoes can become active again due to changes in geological conditions, such as the movement of magma beneath the surface. However, predicting exactly when a dormant volcano will erupt can be challenging.
A volcano can erupt many times. If the pressure from below builds up too much, the volcano will erupt, throwing out very hot gases and lava, until the pressure has been released.
