Grímsvötn is an active subglacial volcano that is located in southeast highlands of Iceland. This volcano reaches an elevation of 5,659 feet and is located in the northwestern side of the Vatnajökull ice-cap. It is comprised of basaltic lava and has the highest frequency of eruptions of any volcano in Iceland. The majority of this volcano resides under Vatnajökull, so its eruptions are primarily subglacial and often cause phreatomagmatic explosions. Grímsvötn produced an eruption in...

Meltwater is water that is released from melting snow or ice. This includes meltwater from glacial ice and ice shelves over oceans. Meltwater is often produced during volcanic eruptions, and can cause dangerous lahars (landslides of wet volcanic debris). When meltwater pools on the surface rather than draining or flowing away, it forms pools known as melt ponds. Meltwater will often refreeze as the temperature drops. Meltwater can also collect or melt under the ice's surface. Sub-glacial...
