The volcano, which sits about 50 miles southeast of the capital, began spewing steam and lava Saturday evening. Mexico´s National Disaster Prevention Center said an increase in activity was...

NASA Studies Volcanoes From Space
2013-05-07 14:59:27

Brett Smith for redOrbit.com - Your Universe Online By using both optical and thermal sensing instruments onboard the Landsat Data Continuity Mission (LDCM) satellite, NASA scientists were able to create a comprehensive image of the Pacific´s Paluweh volcano in mid-eruption. Taken on April 29, 2013, the images show the island volcano with a plume of ash appearing to drift northwest and over Indonesia's Flores Sea. While the satellite's Operational Land Imager detected the white...

Lawrence LeBlond for redOrbit.com - Your Universe Online An Alaskan volcano roared to life on Saturday spewing a cloud of ash, steam and gas into the atmosphere, potentially disrupting a major air traffic route, according to scientists. The Cleveland Volcano, which sits at the western end of Chuginadak Island (part of the Aleutian Islands), erupted in at least three low-level explosions that were not severe enough to cause significant threats to air travel, but did force federal...

Tuya Volcanoes Reveal Glacial, Palaeo-climate Secrets

University of British Columbia Detailed mapping and sampling of the partially eroded Kima' Kho tuya in northern British Columbia, Canada shows that the ancient regional ice sheet through which the volcano erupted was twice as thick as previously estimated Deposits left by the eruption of a subglacial volcano, or tuya, 1.8 million years ago could hold the secret to more accurate palaeo-glacial and climate models, according to new research by University of British Columbia geoscientists....

Volcanic Eruption Forecasting Improvements Needed
2013-04-30 05:24:43

[ Watch the Video: What is a Volcano? ] April Flowers for redOrbit.com - Your Universe Online Recognizing well-established patterns of pre-eruption unrest in monitoring data is vital in volcanic eruption forecasting. To develop better monitoring procedures, however, understanding volcanic eruptions that deviate from these patterns is crucial as well. Diana Roman from the Carnegie Institution for Science led a research team that retrospectively documented and analyzed the period...

Iceland's Hekla Volcano Shows Signs Of Activity, No Eruption Imminent
2013-03-27 11:18:32

Lawrence LeBlond for redOrbit.com - Your Universe Online One of Iceland´s most active volcanoes, Hekla, has been showing signs of potential activity as of late, prompting National Commissioner of the Icelandic Police to declare an “uncertainty phase” for the snow-capped peak. Geologists at the Icelandic Met Office reported unusual seismic activity on the mountain over the past two to three weeks, but said there was no sign that an eruption was imminent. The...

Megavolcanoes Led To End-Triassic Extinction Allowing Dinosaurs To Evolve

WATCH VIDEO: [Drilling Into The Jurassic In New Jersey] Lawrence LeBlond for redOrbit.com - Your Universe Online Popular theory suggests that a massive asteroid smashed into Earth around 65 million years ago wiping most life, including the dinosaurs, off the face of the earth. Now, scientists have found evidence of another planetary cataclysm that occurred some 135 million years before the Cretaceous-Paleogene Extinction (CPE) event. An examination of evidence across three continents...

Volcano Controversy Settled Using Chemistry ‘Trick’
2013-02-12 15:01:41

Brett Smith for redOrbit.com - Your Universe Online Volcanic eruptions have been known to cause global cooling, although the extent of this cooling has been a topic of scientific controversy. Now a team of atmosphere chemists from the Tokyo Institute of Technology and the University of Copenhagen has devised a method for determining which historical cooling periods are the results of volcanic eruptions. When a large volcano erupts, it can propel gases high into the stratosphere where...

New Type Of Volcanic Eruption Described By Scientists
2013-01-21 10:41:33

Brett Smith for redOrbit.com - Your Universe Online Neither explosive nor effusive–there´s a new type of volcanic eruption that was recently described in the latest edition of Nature Geoscience. According to the U.K. and New Zealand scientists who authored the description, volcanic pumice produced by the Macauley volcano in the southwest Pacific is the result of a previously unarticulated type of eruption. “By documenting the shape and density of bubbles in pumices...

Villarrica
2014-08-19 11:03:54

Villarrica, also known as Rucapillán, is an active stratovolcano that is located in Chile and is protected within Villarrica National Park. This volcano is one of five known volcanoes to have a lava lake within its crater and it often produces strombolian eruptions that contain lava flows and incandescent pyroclasts. It is one of three volcanoes that occur along the Gastre Fault Zone, along with the less active Quetrupillán and Lanín volcanoes. During the Valdivia Interglacial, it...

Hoodoo Mountain
2014-08-19 10:23:50

Hoodoo Mountain is flat-topped stratovolcano that is located in British Columbia, Canada and is part of the Northern Cordilleran Volcanic Province and the Pacific Ring of Fire. It is thought to be potentially active and was named for the needle like projections that protrude from it. These lava spines, or hoodoos, reach heights of 492 feet, making it the most distinct mountain in that area of the Boundary Ranges. Hoodoo Mountain is primarily flat-topped, which led volcanologist Jack Souther...

Hualālai
2014-04-10 12:06:55

Hualālai is a dormant shield volcano that is located on the island of Hawaii and is one of five volcanoes that form the island. It reaches an elevation of 8,271 feet and is thought to have emerged from the sea about 300,000 years ago, making it the third youngest volcano on the island. Its shape is rough compared to younger volcanoes and it holds three rift zones that are covered with over one hundred cinder cones and spatter cones. Although it does not hold a caldera at its summit, it does...

Zubair Group

Zubair Group, also known as Zubayr Group or Al Zubair Group, is a chain of volcanic islands belonging to Yemen that are located on top of a shield volcano in the Red Sea. Zubair Group The largest island, known as Zubair, is among the youngest islands, which also include Saba, Saddle, and Haycock. The shield volcano underneath the islands began a period of eruptions and eventually quieted down, followed by a period of explosive and effusive eruptions that formed the islands that are present...

Kohala
2014-04-10 10:03:58

Kohala is an extinct shield volcano that is located on the island of Hawaii and reaches an elevation of 5,480 feet. It is one of five volcanoes that comprise the island of Hawaii and is thought to be about one million years old, although it only emerged from the sea about 500,000 years ago. Because its last eruption is thought to have occurred about 120,000 years ago, based on studies conducted on hardened lava flows, this volcano is not thought to pose a threat to inhabitants on the island....
