Transcript of Hekla

The Amazing Volcano Hekla Formation Volcanic Activity Features Other Cool Facts Right now Hekla is a dormant volcano. Its last eruption was in 2000. The last 4 eruptions happened about every 10 years. The last eruption was not explosive. There was not a pyroclastic flow. Hekla produces basaltic andesite lava. Even though Hekla is dormant it is Iceland's most active volcano. During the middle ages, Icelanders called Hekla the "Gateway to Hell". Scientists think that the longer Hekla stays dormant, the more catastrophic the next eruption will be. Hekla is located at 63.98°N and 19.70°W. Hekla is located along a mid-ocean ridge which is a divergent plate boundary. It is not located anywhere near the Ring of Fire. The mid-ocean ridge is where magma is coming out onto the surface. The magma makes a mound and then there is a volcano.

Hekla is a composite volcano. There are 5 craters on Hekla's peak. Hekla looks like an upside down boat. http://chestofbooks.com/reference/American-Cyclopaedia-5/Hecla-Or-Hekla.html History Hekla has erupted 24 times since the 1104 eruption. The eruptions make the soil more fertile so more people move near Hekla. Right now not many people live near Hekla. Monitoring Safety Hekla gives about a 30 minute warning. Sometimes the volcano doesn't give any warning. The warning Hekla gives is small earthquakes 30-60 minutes before the eruption. http://volcanocafe.wordpress.com/2012/08/11/odd-strain-at-hekla/comment-page-1/ - "Hekla". Online.
