This is from Wikipedia : Kīlauea is a volcano in the Hawaiian Islands, and one of five shield volcanoes that together form the island of Hawaiʻi. Kīlauea means "spewing" or "much spreading" in the Hawaiian language, referring to its frequent outpouring of lava. The PuʻʻŌʻō cone has been continuously erupting in the eastern rift zone since 1983, making it the longest rift-zone eruption of the last 200 years. Thirty-five eruptions have taken place since 1952, not including the current episode. Lava less than 1000 years old covers 90% of Kīlauea, and the volume of erupted material is large enough to pave a road around the world three times.
Kīlauea is one of the most active volcanoes on the planet and an invaluable resource for volcanologists who are able to study it up close due to its exclusively non-violent effusive activity. Since 2008, rising emissions of sulphur dioxide from theHalemaʻumaʻu crater at Kīlauea's summit have led to increased levels of volcanic smog and air quality concerns. Located withinHawaiʻi Volcanoes National Park, Kīlauea is visited by millions of tourists each year, making it the most visited attraction in Hawaii and the most visited volcano in the world.
Despite its relative safety for researchers and visitors alike, Kīlauea is regarded by the USGS as the most dangerous volcano in the U.S. In 2010-2011, lava destroyed several houses in the Kalapana area. In March 2012, lava from Kīlauea completed the destruction of the Royal Gardens subdivision by burning the last remaining home there. According to the United States Geological Survey, the Volcanic-Alert Level for Kīlauea as of April, 2012 is "Watch". A Watch status is used to designate escalating unrest or a minor eruption underway that poses limited hazards.
