Mount St. Helens still active, no signs of impending eruption

In latest information statement from Cascades Volcano Observatory, issued 16:05 UTC today, they report that the analysis of current behavior at Mount St. Helens indicates that the volcano remains active and is showing signs of long-term uplift and earthquake activity, but there are no signs of impending eruption.”Since the end of the 2004-2008 dome-building eruption at Mount St. Helens, scientists at the USGS Cascades Volcano Observatory (CVO) and the Pacific Northwest Seismic Network (PNSN) have been monitoring subtle inflation of the ground surface and minor earthquake activity reminiscent of that seen in the years following the 1980-1986 eruptions.Careful analysis of these two lines of evidence now gives us confidence to say that the magma reservoir beneath Mount St. Helens has bee…

Volcanic plume over Southern Atlantic Ocean revealed through false-color imagery

The South Sandwich Islands, in the far southern Atlantic Ocean, are often shrouded with thick cloud, making it difficult to view the region from space. Sometimes, however, the use of false-color imagery can be used to reveal events that would otherwise be obscured under cloud cover.The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua satellite flew over the South Sandwich Islands on April 19, 2014 and acquired this false-color image of the cloudy scene.Image credit: Jeff Schmaltz/MODIS Land Rapid Response Team, NASA GSFCThis false-color image uses a combination of non-visible (middle infrared and infrared) and visible (red) light captured in bands 7, 2, and 1, respectively, to distinguish clouds from snow and ice. Here the ice-covered islands appear bright tur…

Magnitude of quake scales with maturity of fault, suggests new study by German scientist

The oldest sections of transform faults, such as the North Anatolian Fault Zone (NAFZ) and the San Andreas Fault, produce the largest earthquakes, putting important limits on the potential seismic hazard for less mature parts of fault zones, according to a new study to be presented today at the Seismological Society of America (SSA) 2014 Annual Meeting in Anchorage, Alaska. The finding suggests that maximum earthquake magnitude scales with the maturity of the fault.Identifying the likely maximum magnitude for the NAFZ is critical for seismic hazard assessments, particularly given its proximity to Istanbul.Map showing main tectonic structures around the Anatolian Plate on a base taken from a snapshot from Nasa’s World Wind software.

Fukushima prefectural gov shrank fallout survey / Still 10 Million Bq of Cs-134/137 emitted from Fukushima EVERY HOUR

Fukushima prefectural government announced that they decided to shrink the fallout survey from this April.

Having 10,000,000 Bq of Cesium-134/137 emitted from 4 crippled reactors every single hour, Fukushima prefectural government is going to survey the fallout in Fukushima city only in the rainy days. The reason wasn’t announced.

In Fukushima plant area, 2,900 MBq/km2 of Cesium-134/137 still falls down even based on Tepco’s own report.

Even this January, they measured the spike of fallout level in Fukushima city. The reading was 48.3 MBq/km2 (Cesium-134/137), which was the highest since 10/13/2013.

The situation is not stable at all.

Unusual number of “deep-sea fish” caught dead 2km offshore of Kochi

105 bodies of deep-sea fish “Photonectes” (10~25cm long) were caught in the Pacific on 4/22/2014.

The ecology of this fish is not even well-known. Among 105 bodies, 104 were already dead and 1 is quite in bad shape.

They also caught 9 bodies one day before.

The caught fish was in the fixed net set 2km offshore of Muroto-zaki, in 70m depth.

A professor emeritus from Hokkaido University, Amaoka, who is an expert of deep-sea fish, comments there might have been some abnormality in their habitat.
