Is Eyjafjallajökull a hotspot?
Eyjafjallajokull was formed in two ways: by the divergent plate boundary intersecting Iceland and a hotspot that scientists believe resides under the boundary. Therefore, its height is due to the bubbling up magma from the boundary and its explosiveness is due to the hotspot.
What caused the Eyjafjallajökull eruption?
Why did Eyjafjallajokull erupt? Iceland lies on the Mid Atlantic Ridge, a constructive plate margin separating the North American Plate and the Eurasian plate. The two plates are moving apart due to ridge push along the Mid-Atlantic Ridge. As the plates move apart, magma fills the magma chamber below Eyjafjallajokull.
What type of plate boundary did the Eyjafjallajökull eruption occur on?
The island of Iceland is a part of the Mid-Atlantic Ridge. The diverging Eurasian and North American plates caused the eruptions of Eyjafjallajökull (in 2010) and Bardarbunga (in 2014).
Is Iceland on a hotspot?
The Iceland hotspot is a hotspot which is partly responsible for the high volcanic activity which has formed the Iceland Plateau and the island of Iceland. The presence of water in magma reduces the melting temperature, which may also play a role in enhancing Icelandic volcanism.
What type of hotspot is Iceland?
Iceland is one of the most active volcanic regions in the world, with eruptions occurring on average roughly every five years. About a third of the basaltic lavas erupted in recorded history have been produced by Icelandic eruptions.
What is a hotspot?
Mobile WiFi hotspots Did you know that you can use your iPhone or many Android smartphones as a WiFi hotspot? By turning on this feature, your phone uses its cellular data to create a WiFi hotspot. You can then connect a computer or other device to this hotspot to access the internet.
What caused Eyjafjallajökull eruption 2010?
The eruptions of Iceland’s volcano Eyjafjallajökull in 2010 were apparently triggered by a chain reaction of expanding magma chambers that descended into the Earth, a group of researchers now says.

Is Eyjafjallajökull on a divergent plate boundary?
Iceland rests along the Mid Atlantic Ridge, a divergent tectonic plate boundary at the bottom of the Atlantic Ocean.
What type of plate boundary is the Iceland?
divergent plate boundary
Iceland lies on the Mid Atlantic Ridge, a divergent plate boundary where the North American Plate and the Eurasian Plate are moving away from each other.
Why is Iceland a volcanic hotspot?
Iceland formed by the coincidence of the spreading boundary of the North American and Eurasian plates and a hotspot or mantle plume – an upsurge of abnormally hot rock in the Earth´s mantle. As the plates moved apart, excessive eruptions of lava constructed volcanoes and filled rift valleys.
Is Hawaii a hot spot?
The Hawai’i hotspot is a volcanic hotspot located near the namesake Hawaiian Islands, in the northern Pacific Ocean. While most volcanoes are created by geological activity at tectonic plate boundaries, the Hawaii hotspot is located far from plate boundaries.
