New Giant Volcano Below Sea Is Largest in the World
By Brian Clark Howard | National Geographic
Tamu Massif in the northwest Pacific challenges traditional views of ocean science.
A volcano the size of New Mexico or the British Isles has been identified under the Pacific Ocean, about 1,000 miles (1,600 kilometers) east of Japan, making it the biggest volcano on Earth and one of the biggest in the solar system.
Called Tamu Massif, the giant shield volcano had been thought to be a composite of smaller structures, but now scientists say they must rethink long-held beliefs about marine geology.
“This finding goes against what we thought, because we found that it’s one huge volcano,” said William Sager, a geology professor at the University of Houston in Texas. Sager is lead author in a study about the find that was published this week in the peer-reviewed journal Nature Geoscience.
“It is in the same league as Olympus Mons on Mars, which had been considered to be the largest volcano in the solar system,” Sager told National Geographic.
Tamu Massif is a rounded dome that measures about 280 by 400 miles (450 by 650 kilometers), or more than 100,000 square miles. Its top lies about 6,500 feet (about 2,000 meters) below the ocean surface, while the base extends down to about 4 miles (6.4 kilometers) deep. Tamu Massif dwarfs the largest active volcano on Earth, Mauna Loa in Hawaii, which measures about 2,000 square miles (5,200 square kilometers).
Made of basalt, Tamu Massif is the oldest and largest feature of an oceanic plateau called the Shatsky Rise in the northwestern Pacific Ocean. The total area of the rise is similar to Japan or California.
Sager started studying Tamu Massif about 20 years ago. He named it Tamu Massif because Tamu is short for Texas A&M University, where the scientist worked at the time; massif is French for “massive” and is a scientific term for a large mountain.

Rome's Arch of Titus Now Represents a Jewish Triumph
Though not on a par with the universally recognizable Colosseum, the Arch of Titus remains one of the most iconic relics from Rome's ancient imperial glory days. The grand arch is located just south-east of the Roman Forum (main center of ancient Rome). It was opened in 82 AD by the Roman Emperor Domitian, shortly after the death of ...
IQ, Psy Ops and the "Civilization" of the Scam
Cognitive dissonance is the firewall that exists in most minds when confronted with a challenge to their basic beliefs about the world. As it is human nature to avoid admitting being in error or having been duped, for most humans the ego zealously flees the admission to oneself of significant error.Challenges to our worldviews or paradigms of belief are also ...

Increasing Cosmic Rays
Driving Force in Climate Changes, Volcanos and Earthquakes
Back in 1996 Danish physicists suggested that cosmic rays, energetic particles from space, are important in the formation of clouds. Since then, experiments in Copenhagen and elsewhere have demonstrated that cosmic rays actually help small clusters of molecules to form. By firing a particle beam into a cloud chamber, physicists in Denmark and ...
