It&#8217;s a bit like a bottle of fizzy pop: gas is trapped in the liquid but if you shake the bottle the gas wants to escape. This builds pressure inside the bottle and when you release the pressure by opening the bottle, the gas rushes out of the top carrying some of the liquid with it.<\/p>\n\n\n\n<p>Phreatomagmatic eruptions are a type of explosive eruption that results from magma erupting through water. The second phase of the\u00a0Eyjafjallaj\u00f6kull eruption in 2010 was phreatomagmatic as a result of magma erupting under ice. Some submarine volcanoes are phreatomagmatic if the magma is gas-rich, for example\u00a0<a rel=\"noreferrer noopener\" href=\"https:\/\/volcano.si.edu\/volcano.cfm?vn=372010\" target=\"_blank\">Surtsey<\/a>\u00a0in Iceland.

They also send ash high into the atmosphere, forming\u00a0plumes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"effusive\">Effusive eruptions<\/h2>\n\n\n\n<p>If a magma has low viscosity (it is runny), gas can escape easily, so when the magma erupts at the surface it forms lava flows. These eruptions are (relatively!) gentle, effusive eruptions. If a magma rises very slowly within the conduit. or throat, of the volcano, all the gas can escape. When the magma is viscous (or sticky), it can&#8217;t flow when it reaches the surface, so it builds up forming a\u00a0<a href=\"https:\/\/www.bgs.ac.uk\/discovering-geology\/earth-hazards\/volcanoes\/how-volcanoes-form\/#dome\">lava dome<\/a>.<\/p>\n\n\n\t\t\t\t<div  class=\"owl-carousel carousel-primary-color carousel owl-theme thumbs-carousel-js\">\n\t\t\t\t\t<div class=\"item\"><figure  class=\"img-wrap\"><a href=\"https:\/\/www.bgs.ac.uk\/wp-content\/uploads\/2020\/04\/effusive_monserrat_website.jpg\" data-toggle=\"lightbox\" data-footer=\"&lt;p&gt;Effusive activity on an andesitic lava dome, Soufriere Hills Volcano, Montserrat, December 1996.
