Ash from dinosaur-era volcanoes linked with shale oil, gas

Tue, 13 Mar 18 00:16:30 -0700

Nutrient-rich ash from an enormous flare-up of volcanic eruptions toward the end of the dinosaurs' reign kicked off a chain of events that led to the formation of shale gas and oil fields from Texas to Montana.

A new discovery that makes possible prediction immediately before plasma loss

Thu, 01 Mar 18 00:08:30 -0800

At the National Institutes of Natural Sciences National Institute for Fusion Science we have clarified for the first time a trigger event for sudden phenomena in which part of a magnetically confined plasma has been suddenly lost in the Large Helical Device (LHD). By capturing that change, we have become able to predict phenomena immediately before they occur. These results will contribute significantly to research that predicts solar flares, auroras, and other sudden phenomena.

Another clue for fast motion of the Hawaiian hotspot

Tue, 27 Feb 18 00:13:10 -0800

Recent studies have suggested that the Hawaiian hotspot moved relatively quickly southward in the period from 60 to about 50 million years ago. This hypothesis is supported by a new study of Kevin Konrad and colleagues. They have evaluated new rock dating of the Rurutu volcanic chain and added data from the Hawaiian-Emperor chain and the Louisville chain. It shows that the Hawaiian-Emperor hotspot displays strong motion between 60 and 48 million years ago.

New insight into how magma feeds volcanic eruptions

Thu, 22 Feb 18 00:01:50 -0800

A novel research study by scientists at the University of Liverpool has provided new insights into how molten rock (magma) moves through the Earth's crust to feed volcanic eruptions. Using laboratory experiments involving water, jelly and laser imaging, researchers were able to demonstrate how magma magma flows through the Earth's crust to the surface through magma-filled cracks called dykes.

Infant skull binding shaped identity, inequality in ancient Andes

Wed, 21 Feb 18 00:04:20 -0800

The idea of binding and reshaping a baby's head may make today's parents cringe, but for families in the Andes between 1100-1450, cranial modification was all the rage.

Stanford scientists eavesdrop on volcanic rumblings to forecast eruptions

Fri, 16 Feb 18 00:16:30 -0800

NASA shows new Tongan island made of tuff stuff, likely to persist years

Mon, 11 Dec 17 00:15:40 -0800

In late December 2014, a submarine volcano in the South Pacific Kingdom of Tonga erupted, sending a violent stream of steam, ash and rock into the air. The ash plumes rose as high as 30,000 feet (9 kilometers) into the sky, diverting flights. When the ash finally settled in January 2015, a newborn island with a 400-foot (120-meter) summit nestled between two older islands -- visible to satellites in space.

Unearthing the underground effects of earthquakes and volcanoes

Wed, 06 Dec 17 00:12:50 -0800

Kyushu University (Japan) researchers analyzed high-resolution seismic velocity data from 36 seismograph stations across the island of Kyushu to identify variations before, during, and after the MW 7.0 2016 Kumamoto earthquake. Velocity decreased in the region of the rupture fault when the earthquake struck, and then gradually recovered, although this recovery showed spatial variability. This variability corresponded to aftershock concentration and volcanic activity. The findings may be useful for disaster prediction and preparedness.

Submarine volcanoes add to ocean soundscape

Mon, 04 Dec 17 00:11:20 -0800

Most volcanoes erupt beneath the ocean, but scientists know little about them compared to what they know about volcanoes that eject their lava on dry land. Gabrielle Tepp of the USGS thinks that with improved monitoring, we can learn more about submarine eruptions, which alter the ocean soundscape. During the 174th ASA meeting, Dec. 4-8, 2017, Tepp will discuss the challenges and benefits of remote monitoring and what it can teach about submarine volcanoes.

Climate changes triggered immigration to America in the 19th century

Tue, 21 Nov 17 00:05:20 -0800

From Trump to Heinz, some of America's most famous family names and brands trace their origins back to Germans who emigrated to the country in the 19th century. Researchers from the University of Freiburg have now found that climate was a major factor in driving migration from Southwest Germany to North America during the 19th century. The results are published today in Climate of the Past, a journal of the European Geosciences Union.

Filling the gap: High-latitude volcanic eruptions also have global impact

Mon, 20 Nov 17 00:04:00 -0800

Cool idea: Magma held in 'cold storage' before giant volcano eruption

Mon, 06 Nov 17 00:16:20 -0800

Long Valley, California, has long defined the 'super-eruption.' About 765,000 years ago, a pool of molten rock exploded into the sky. Within one nightmarish week, 760 cubic kilometers of lava and ash spewed out in the kind of volcanic cataclysm we hope never to witness. A new study shows that the giant body of magma -- molten rock -- at Long Valley was much cooler before the eruption than previously thought.

New magma pathways after giant lateral volcano collapses

Mon, 23 Oct 17 00:04:10 -0700

Giant lateral collapses are huge landslides occurring at the flanks of a volcano. Such collapses are rather common events during the evolution of a large volcanic edifice, often with dramatic consequences such as tsunami and volcano explosions. These catastrophic events interact with the magmatic activity of the volcano, as a new research by scientists of GFZ German Research Centre for Geosciences in Nature Communications suggests.

Mercury is altering gene expression

Tue, 15 Aug 17 00:13:50 -0700

Mercury causes severe neurological disorders in people who have consumed highly contaminated fish. Whereas we know about the element's extreme toxicity, what happens further down the food chain, all the way down to those microalgae that are the first level and the gateway for mercury? By employing molecular biology tools, a team of researchers from UNIGE measured the way mercury affects the gene expression of algae, even when its concentration in water is very low.

Innovative way to understand nature of an entire tiny particle

Thu, 10 Aug 17 00:07:30 -0700

New research from the University of New Hampshire has led to the development of a novel technique to determine the surface area and volume of small particles, the size of a grain of sand or smaller. Due to their tiny size, irregular shape and limited viewing angle, commonly used microscopic imaging techniques cannot always capture the whole object's shape often leaving out valuable information that can be important in numerous areas of science, engineering and medicine.

Slow earthquakes occur continuously in the Alaska-Aleutian subduction zone

Wed, 12 Jul 17 00:09:10 -0700

Seismologists at the University of California, Riverside studying earthquakes in the seismically and volcanically active Alaska-Aleutian subduction zone have found that 'slow earthquakes' are occurring continuously, and could encourage damaging earthquakes. Slow earthquakes are quiet, can be as large as magnitude 7, and last days to years. Taking place mainly at the boundary between tectonic plates, they happen so slowly that people don't feel them.

Crystals help volcanoes cope with pressure

Mon, 10 Jul 17 00:15:00 -0700

University of Alaska Fairbanks researchers have discovered that volcanoes have a unique way of dealing with pressure -- through crystals. According to a new study published in the Journal of Geology, if enough crystals can develop in rising magma, then a network of microscopic crystals can lessen the internal pressure of rising magma and reduce the explosiveness of eruptions.
