Iceland is an amazing island filled with bubbling volcanoes and icy glaciers. One actually erupted just two years ago leaving many towns under ashes.
As we were getting ready for London my cousin was chosen to play on a professional soccer (or, as they say, “futball”) team in Iceland so we did what any good family would do and took a slight detour to The Land of Fire and Ice.
Mount Etna, the most active volcano in Europe, has been erupting off and on since early July. Although the volcano erupts often, the lava moves slowly, so there almost never any danger. The volcano has become more active during the last 50 years.

On May 21 Iceland’s most active volcano, Grímsvötn began erupting, spewing a 12-mile-high (19-kilometer-high) cloud of ash. The eruption has also generated volcanic lightning. Grímsvötn volcano is one of seven volcanoes located under the Vatnajökull ice cap.
Icelandic airports have canceled flights because of the ash, and London’s Heathrow Airport may be affected by the end of the week. In 2010, Iceland’s Eyjafjallajökull volcano erupted, disrupting air traffic across Europe for several days.

On May 18, 1980, the Mount St. Helens volcano in Washington State erupted. The eruption (which was heard hundreds of miles away) blew off the top of the mountain, destroyed miles of forest, and killed 57 people.
In the 30 years since the eruption, scientists have been able to study how an ecosystem recovers from a volcanic eruption. What was once a desolate, gray blast zone in 1980 is now home to many plants and animals. Although it has not had an eruption of the same size since 1980, Mount St. Helens is one of the most active volcanoes in the United States and could erupt again.

An underwater volcano 745 miles south of Tokyo, Japan, erupted earlier this month. The volcano, Fukutoku-Okanoba, last erupted in July 2005. Past Fukutoku-Okanoba eruptions have caused miniature islands to form, but the ocean’s waves have washed them away. The eruption of underwater volcanoes can also form very large islands, like those that make up the Hawaiian Islands.
Will this eruption create a new island? “We have seen no evidence of an island being created yet, but it is possible, and we will continue to monitor the situation,” said Keiji Doi of the Japan Meteorological Agency.

Alaska’s Mount Redoubt erupted six times between Sunday night and Saturday morning, sending an ash cloud 9.5 miles (15 kilometers) into the air! The eruptions also caused small earthquakes and mudflows. The volcano could keep erupting for days… weeks… or even months!
Mount Redoubt wasn’t the only recent volcano eruption. An undersea volcano in Tonga also erupted last week. Tonga is an archipelago (group of islands) in the Pacific Ocean. The eruption has sent up ash, smoke, and steam. Underwater volcanoes can build islands as the magma builds up–that’s how the Hawaiian Islands were formed.
