New theory of why midcontinent faults produce earthquakes
A new theory may solve the mystery of why the New Madrid fault, which lies in the middle of the continent and not along a tectonic plate boundary, produces large earthquakes such as the ones that shook the eastern United States in 1811 and 1812.

Accepted theory explaining frequent eruptions at Italy’s Stromboli volcano questioned
One volcano that volcanologists believe they understand fairly well is Italy's Stromboli, which has been erupting every five to 20 minutes for thousands of years, spewing fountains of ash and magma several meters into the sky. For several decades, scientists have pretty much used one theory to explain what is causing huge amounts of gas to erupt so frequently: swimming-pool-sized bubbles that travel through a few hundred meters of molten magma before popping at the surface. But they may be wrong, according to new research.

Indonesia's puzzling Banda arc: New findings explain mystery behind geological development
The Banda arc -- a gigantic 1,000km long, 180-degree curve in eastern Indonesia -- has puzzled geologists for many years, with much debate and controversy surrounding its complex origin and evolution. A solution to this enigma, resolving many of the previous problems, has finally been found.

Evidence of water in lunar rocks: Water on moon may be widespread, similar to Earth's
That dry, dusty moon overhead? Seems it isn't quite as dry as it's long been thought to be. Although you won't find oceans, lakes, or even a shallow puddle on its surface, a team of geologists has found structurally bound hydroxyl groups (i.e., water) in a mineral in a lunar rock returned to Earth by the Apollo program.

Final instruments on NASA climate/weather satellite integrated
The last of five instruments slated to fly on the upcoming NPOESS Preparatory Project (NPP) climate and weather satellite have been successfully integrated, according to NASA officials. The polar-orbiting satellite is scheduled to launch in late 2011.

Expedition to Mid-Cayman Rise identifies unusual variety of deep sea vents
The first expedition to search for deep-sea hydrothermal vents along the Mid-Cayman Rise has turned up three distinct types of hydrothermal venting, report marine biologists. The work was conducted to search extreme environments for geologic, biologic, and chemical clues to the origins and evolution of life.

Breakthrough achieved in explaining why tectonic plates move the way they do
Geophysicists have developed a new theory to explain the global motions of tectonic plates on the earth's surface. The new theory extends the theory of plate tectonics -- a kinematic description of plate motion without reference to the forces behind it -- with a dynamical theory that provides a physical explanation for both the motions of tectonic plates as well as motion of plate boundaries.

Noninvasive probing of geological core samples
Tools to measure a core sample's electrical anisotropy have been sadly lacking, according to a group of researchers. To solve this problem, they found inspiration in a type of logging technology currently used by the modern oil industry. They created a device capable of noninvasively measuring electrical conductivity.

Finding diamonds: Scientists' work improves odds
While prospectors and geologists have been successful in finding diamonds through diligent searching, one professor and his team's work could help improve the odds by focusing future searches in particular areas.

Geo-neutrinos: Discovery of subatomic particles could answer deep questions in geology
An international team has detected subatomic particles -- geo-neutrinos -- deep within Earth's interior. The discovery could help geologists understand how reactions taking place in the planet's interior affect events on the surface such as earthquakes and volcanoes. Someday, scientists may know enough about the sources and flow of heat in Earth to predict events like the recent volcanic eruption in Iceland.
