A nice day for a walk
With much to see all around
I was quite happy for the rain
To keep the skeets down

Earth’s Largest Volcano Found In Pacific Ocean
Olympus Mons (pictured) is regarded as the largest volcano in the Solar System, but there is a new kid on the block. NASA
A megavolcano found at the bottom of the Pacific Ocean is being reported as the largest single volcano on Earth. Tamu Massif, as the megavolcano is called, may be as voluminous as Olympus Mons on Mars, which is regarded as the Solar System’s largest known volcano.
Tamu Massif, the inactive volcano, was previously thought to be a string of volcanoes rather than one enormous feature. It is part of an underwater mountain range called the Shatsky Rise, which covers an area as large as California state in the US. Found close to the east of the coast of Japan, Shatksy Rise formed some 145 million years ago as huge amounts of magma flowed onto the ocean floor at a point where three microplates of Earth’s crust meet.

While Olympus Mons is much taller (>25km) than Tamu Massif (about 4km), its base is smaller. Massive lava flows would have rapidly flowed along shallow slopes to create Tamu Massif, which has a 650km-wide base, nearly as big as New Mexico in the US. Volcanoes created entirely due to such lava flow are called shield volcanoes because they resemble a warrior’s shield.
The volcano’s structure is described in the journal Nature Geoscience by scientists from the US, the UK and Japan. Tamu Massif is named after Texas A&M University, where the lead researcher William Sager is based.

Although rocks from Tamu Massif had previously been identified as volcanic crystallised lava, its size made geologists believe it was the result of many volcanic eruptions that may have occurred over a period of many millions of years. Now it seems that this may have been closer to a distinct but enormous flood of lava.
To verify that hypothesis Sager’s team collected new samples and data aboard an ocean-going science research vessel called Marcus G. Langseth. They drilled samples from the ocean floor, and poked Tamu Massif with seismic waves, measuring the response using seismometers. They were able determine whether the rocks may have come from different eruptions. From all the new data they acquired it seems that lava flow emerged from a single central magma vent.
Time on such research vessels is expensive and this report is first of its kind looking at large underwater volcanoes. Much of Earth’s ocean floor remains to be thoroughly explored. This makes Sager believe that there may be even bigger volcanoes out there.

New Madrid
America’s Heartland is Earthquake Country
Posted: 30 Sep 2013 06:30 AM PDT
New research provides insight on why the New Madrid Seismic Zone is unique and may continue to pose a higher earthquake risk than adjacent areas in the central United States.
Using innovative and sophisticated technology, scientists now have high-resolution imagery of the New Madrid Seismic Zone, allowing them to map the area in more detail than ever before. The maps allow for greater understanding of the weak rocks in this zone that are found at further depths in the Earth’s mantle compared to surrounding areas. Scientists also determined that earthquakes and their impacts are likely to be narrowly concentrated in this zone.
U.S. Geological Survey scientists led this research and recently published their findings in the journal, Earth and Planetary Science Letters.
A swarm of some of the largest historical earthquakes in the nation occurred in the New Madrid Seismic Zone, in particular three earthquakes greater than magnitude 7 occurred from 1811 to 1812. There have been several smaller, yet still significant, earthquakes in the area since then. This zone extends about 165 miles from Marked Tree, Ark., to Paducah, Ky. and the southern end of the zone is about 35 miles northwest of Memphis, Tenn.
“With the new high-resolution imagery, we can see in greater detail that the New Madrid Seismic Zone is mechanically weaker than surrounding areas and therefore concentrates movement and stress in a narrow area,” said USGS scientist Fred Pollitz, who is the lead author of this research. “The structure beneath this zone is unique when compared to adjacent areas in the central and eastern United States. A more in-depth understanding of such zones of weakness ultimately helps inform decisions such as the adoption of appropriate building codes to protect vulnerable communities, while also providing insight that could be applied to other regions across the world.”
Prior to this research, the New Madrid Seismic Zone has been mapped by the USGS as an area of high seismic hazard, but those assessments were a consequence of a short (about 4,500 years) earthquake record for the area.
This research specifically investigated the Reelfoot Rift area, which is a 500-million-year-old geologic feature that contains the New Madrid Seismic Zone in its northernmost part. Scientists imaged rocks deep beneath Earth’s surface to see their characteristics and understand their mechanical behavior, especially their ability to withstand the huge stresses constantly placed on them.
A surprising finding was that weak rocks underlie the fault lines in the crust of the Reelfoot Rift and extend more than 100 miles down into the mantle. In contrast, weak rocks in other ancient rift zones in the central and eastern United States bottom out at much shallower depths. These weak mantle rocks have low seismic velocity, meaning that they are more susceptible to concentration of tectonic stress and more mobile.
USGS scientists used data from USArray, which is a large network of seismometers that is a component of the EarthScope program of the National Science Foundation. These seismometers provide images of the crust and mantle down to 120 miles (200 kilometers) beneath the surface using the methods employed by these scientists.
“Our results are unexpected and significant because they suggest that large earthquakes remain concentrated within the New Madrid Seismic Zone,” said USGS scientist Walter Mooney, the co-author of the report. “There are still many unknowns about this zone, and future research will aim to understand why the seismic zone is active now, why its earthquake history may be episodic over millions of years, and how often it produces large quakes.”
In the future, USGS scientists plan to map the seismic structure of the entire nation using USArray. This effort started in California in 2004, is focusing on the east coast next, and will then move to Alaska. All of the USArray and other Earthscope efforts will also help inform the USGS National Seismic Hazard Maps.
