Megathrust Earthquakes
2013-06-13 05:25:12

redOrbit Staff & Wire Reports - Your Universe Online In an attempt to better prepare for future massive “megathrust” earthquakes along the west coast of Canada, researchers have prepared a record of earthquake history in southern British Columbia. Their findings, which were published Wednesday in the Canadian Journal of Earth Sciences, will play an important role in helping scientists, government officials and the general public understand the size and frequency of...

'Caldas Tear' Resolves Seismic Activity Beneath Colombia
2013-06-06 20:49:15

Seismological Society of America Colombia sits atop a complex geological area where three tectonic plates are interacting, producing seismicity patterns that have puzzled seismologists for years. Now seismologists have identified the "Caldas tear," which is a break in a slab that separates two subducting plates and accounts for curious features, including a "nest" of seismic activity beneath east-central Colombia and high grade mineral deposits on the surface. In a paper published in...

Volcano Monitoring Program Searches Iceland For Early Signs Of Eruptions
2013-05-23 13:49:01

Lee Rannals for redOrbit.com — Your Universe Online A new collaborative project called FutureVolc is aimed at trying to improve monitoring of Iceland's volcanoes. FutureVolc started October 1, 2012 and is funded by the Environmental/FP7 program of the European Commission. The project says its main objectives are to establish an integrated volcano monitoring system through European collaboration, develop new methods to evaluate volcanic crises, increase scientific understanding of...

Earth’s Ice Sheets More Stable Than Once Thought
2013-05-17 10:44:21

April Flowers for redOrbit.com - Your Universe Online For decades, researchers have used ancient shorelines to predict the stability of today´s largest ice sheets in Greenland and Antarctica. High shoreline markings from three million years ago as Earth was going through a warm period were thought to be evidence of a high sea level due to ice sheet collapse at the time — an assumption that has led many scientists to believe that if the world´s largest ice sheets collapsed...

Fossils Help Researchers Learn More About Cascadia Quake Of 1700
2013-05-15 18:17:53

Brett Smith for redOrbit.com — Your Universe Online Scientists have long been baffled by a massive earthquake that struck the western coast of North America in 1700. Since that part of the continent was only sparsely populated by indigenous peoples, the lack of official records has made studying the event quite difficult. According to a new report in the Journal of Geophysical Research: Solid Earth, a research team from the University of Pennsylvania has discovered new details...

Arabian Sea Earthquake Risk Predictions Were Underestimated
2013-05-13 16:04:27

Lee Rannals for redOrbit.com — Your Universe Online Researchers writing in the journal Geophysical Research Letters say the western Indian Ocean earthquake and tsunami hazard potential is greater than scientists had originally predicted. Scientists from the University of Southampton say the risk from undersea earthquakes and tsunami beneath the Arabian Sea at the Makran subduction zone was underestimated. They said their findings highlight the need for further investigation of...

Mexico's Popocatepetl Volcano Increases Activity, Warnings Issued
2013-05-13 10:49:50

Lawrence LeBlond for redOrbit.com - Your Universe Online Authorities in Mexico have raised the alert level for towns in two central states and the capital after an increased amount of explosive activity has occurred at Popocatepetl volcano, Mexico´s second highest peak at 17,900 feet. 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...

Atlantis Found In Brazil Via Discovery Of Ancient Granite Rock
2013-05-09 09:08:58

Lawrence LeBlond for redOrbit.com - Your Universe Online First mentioned in two dialogues (Timaeus and Critias) by Plato in 360 BC, the legendary island of Atlantis has long been sought by historians, archaeologists, and explorers alike. Said to have originally existed between South America and Africa, this sunken island has been searched for in no less than dozens of locations worldwide, from Bimini to the Black Sea. In a new twist, a team of scientists from Brazil and Japan say they...

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...

Nyamuragira is an active shield volcano that is located in the Democratic Republic of the Congo. This volcano, which is part of the Virunga Mountains, reaches an elevation of 10,033 feet and is the most active volcano in Africa. This volcano is shorter than Nyiragongo, which it shares an area with, and has a low shield profile. It holds a large amount of sulfur dioxide and is blamed for much of the volcano related sulfur dioxide content in the atmosphere. Nyamuragira has erupted over forty...

Imbabura Volcano
2014-10-04 17:36:59

Imbabura Volcano is an inactive stratovolcano that is located in Ecuador and is part of the southern Ring of Fire and one of many volcanoes created along an arc by the subductions of the Coolyo Plate underneath the South American Plate. This volcano was shaped by strombolian eruptions, which are less violent than plinian eruptions and are characterized by the expulsion of lapilli, lava bombs, and cinders as well as the accumulation of tephra around the point of eruption like a vent....

Mount Nyiragongo

Nevado del Ruiz, also known as La Mesa de Herveo, is an active stratovolcano that is located along the border of the Colombian territories, or departments, of Caldas and Tolima. It reaches an elevation of 17,457 and is shaped like a cone. This volcano is protected within Los Nevados National Natural Park, along with many other volcanoes, and it is a popular tourist destination. Winter activities like skiing are conducted here as well as hiking and fishing. Nevado del Ruiz is part of the...

Galeras
2014-08-28 10:56:28

Galeras is a stratovolcano that is located in Nariño, a Colombian controlled territory. This volcano, which reaches a height of 14,029 feet, is highly active and the most active volcano in Colombia. It primarily contains andesite and holds two calderas that were created by eruptions in the past 560,000 years. Although it is shaped like a horseshoe, eruptions have caused a cone shaped structure to build up in one of the calderas. It was labeled a Decade Volcano in 1991, despite its recent...
