63: Steam plume eruption recorded at Vanuatu’s Mt. Gharat Volcano

June 22, 2013VANUATUJust 20 kilometers (12 miles) in diameter, Gaua Island is actually the exposed upper cone and summit of a stratovolcano that is 3,000 meters (10,000 feet) high and 40 kilometers (25 miles) in diameter. Most of the volcano is submerged beneath the Pacific Ocean. Also known as Santa Maria Island, Gaua is part of the Vanuatu Archipelago, a group of volcanic islands in the South Pacific Ocean governed by the Republic of Vanuatu. According to the Smithsonian Institution Global Volcanism Program, the most recent report of eruption activity at Gaua was a steam plume observed on April 29, 2013. This photograph records subsequent steam emissions observed on May 31, 2013, by an astronaut on the International Space Station. The steam plume extends east-southeast from its likely source at Mount Gharat (also spelled Garat or Garet), a historically active cinder cone located along the southwest flank of a 6 by 9 kilometer (4 by 6 mile) collapsed summit caldera. Gaua is one of several volcanoes monitored by the Vanuatu Geohazards Observatory. The dark blue-green waters of Lake Letas, formed within the caldera, are visible at image center. The majority of Santa Maria Island is covered in green vegetation, with areas directly west and south of Mount Gharat covered with grey ash deposits. Patchy cloud cover is visible to the west and south, but is easily distinguished from the steam plume by its linear nature and brighter tone. –NASA

    My oh my! 63 different volcanoes erupting in half a year. 2013 seems to be a pretty explosive year so far.

    Is planet Earth above average for
    earthquakes and eruptions this year?
