Volcano Report
... A volcanic eruption occurs when lava flows or ejects from a vent. Vents can be located at the top of the cone shaped mountain and also on its sides, and one volcano can have many vents. Eruptions can be violent or quiet. Violent eruptions occur because new lava, steam, and gases, such as carbon diox ...
