Volcanic gases are gases that have escaped or been released from the Earth during volcanic activity. In most cases, these gases were trapped in magma, the superheated, molten rock beneath the Earth’s crust. If magma is ejected during a volcanic eruption, these gases will be violently released...

Volcanoes form as a result of shifting tectonic plates beneath the earth's surface. Explore the process of volcanic formation, discover the Ring of Fire, and examine the types of volcanoes found throughout the globe. From Cornfield to Volcano ...
Although experts believe “the probability of a volcanic eruption is relatively low,” the relentless inflation and recent shaking of Italy's Campi Flegrei caldera raise questions for experts—and locals.
First of all, volcanoes are the reason Iceland exists.The area where volcanic activity has created the island over 18 million years rests on a constructive plate boundary called the Mid-Atlantic Ridge, which is part of one of the world's longest mountain ranges (albeit underwater) at nearly...
Sometimes they consist of single waves, but very often a sequence of waves is created. Anything that causes a seafloor disturbance can produce a tsunami. Earthquakes, volcanic explosions, undersea landslides, and meteor impacts are common causes. ...

A volcano is typically found where two or more tectonic plates are either converging or diverging. The result is a rupture in the surface of the planet which then allows hot ashes, gas, and volcanic lava to rise up from the magma chamber located undernea
7.Volcanic Hazards: Volcanic eruptions can pose various hazards: Pyroclastic Flows:Extremely dangerous and fast-moving flows of hot gases, ash, and volcanic rocks. Lahars:Rapid mudflows triggered by volcanic activity, often involving melted snow or ice. ...
