What is the term for a volcano unlikely to erupt again?
They term this an extinct volcano if there is no longer a supply of magma to the chamber underlying the volcano or dormant if there is (as there is therefore still a chance of a future eruption).
How did the caldera on the volcanic island of Krakatau form?
It is a Strato Volcano.
Is there a possibility that a volcano will erupt in the same day as a other one or in the same week?
Yes. In an average year about 50 volcanoes erupt worldwide. Taken as a simple average this works out to a little less than one eruption every week. In addition, an eruption may continue, either continuously or sporadically, for weeks or even years. Except in a few cases of a shared magma supply, what one volcano is doing will not affect another. Given how often some volcano erupts, it would not be uncommon for two volcanoes hundreds or thousands of miles to erupt on the same day, though these eruptions would be unrelated to one another.
Can a towns water supply conite with sulfur before a volcano erupts?
yes
What rock forms when Mount St Helens erupts?
Mt. St. Helens has erupted a very broad spectrum of igneous rocks. Primarily it is known as an explosive volcano meaning that it most commonly erupts Dacite, which has a high amount of silica present in the rock. However, throughout the geologic history of the volcano it has erupted everything from Basalt (very fluid, Hawaiian style) magma, to Rhyodacite (very sticky, explosive) style of magma. The silica content in a volcanoes magma supply primarily determines if the volcano will tend to have an explosive type of eruption or if it will tend to fountain lava. Mt. St. Helens having primarily Dacite tends to be a commonly more explosive volcano when it goes through its eruption periods. For a further detailed geologic history of Mt. St. Helens please see related links to the Geologic History of Mt. St. Helens as provided by the United States Geological Survey, Cascades Volcano Observatory.

Will the crater on top of a volcano contain a lake?
The volcanic craters that contain lakes are not extremely rare, however for a lake to form the volcano must have a low level of activity. If the temperature of the volcano gets too warm preceeding an eruption or shortly after an eruption the water will simply convert to steam and will not become a lake. However if the crater is cool enough and is enclosed, as long as there is a supply of water a crater lake will eventually form within the volcano.
What is an extinict volcano?
An extinct volcano is a volcano that is completely cut off of its magma supply.
What warning sings were missed by the people of Pompeii?

What is the difference between an extinct and a dormant earthquake?
An earthquake is a result of movement along a fault line, so they aren't classified as extinct and dormant. If you mean volcanoes, an extinct volcano is one that scientists classify as unlikely to erupt again because it no longer has lava supply. A dormant volcano is one scientists believe can still be active but has not had an eruption in recent years.

It is a Strato Volcano.

What type of volcano is Mount Yasur?
Mount Yasur is on the Indo-Australian Plate and Pacific Plate boundary. This provides the volcano with a constant supply of fresh rock to erupt.
Will lake toba super volcano erupt again?
Most likely. The volcano has continued to erupt regularly since its last massive explosion in 1883.
Why do newly formed volcanic islands have a rich supply of minerals?
Volcanic islands have a rich supply of minerals because when a volcano erupts it produces lava (magma) and that lava has lots of rocks and minerals in it.
