Solid Earth Tectonic Processes News Archive


A tectonic plate that disappeared millions of years ago has turned up in Central California and Mexico. New research from Brown University found that part of the Baja region of Mexico and part of central California near the Sierra Nevada mountains sit upon slabs of this long-lost plate. It’s a big breakthrough in how we…

The Geological Society of London, the world’s oldest and one of its most prestigious geological organizations, has announced it will award medals to two scientists working at the Bureau of Economic Geology, Martin P. A. Jackson, senior research scientist, and Christopher Jackson, senior research fellow. Martin Jackson will receive the William Smith Medal, presented for…

Researchers from Amherst College and The University of Texas at Austin have described a new technique that might one day reveal in higher detail than ever before the composition and characteristics of the deep Earth.

It’s the nightmare scenario: A magnitude 7.8 earthquake begins at the southern end of the San Andreas Fault and the rupture continues moving northwest 200 miles along the fault to a spot about 50 miles north of Los Angeles. Buildings collapse, wildfires spark, and electric power and water systems are damaged. Experts project such an…

The 2010 Earthquake in Haiti, 2000 Years Ago

Scientists have discovered underwater evidence that Haiti’s unusual 2010 earthquake may not have been the first of its kind in the region. They took core samples from the seafloor that reveal a 2000-year-old sequence of sediment layers closely resembling landslide deposits triggered by the 2010 quake, indicating an older event of similar violence and other…

Most earthquakes in the Barnett Shale region of North Texas occur within a few miles of one or more injection wells used to dispose of wastes associated with petroleum production such as hydraulic fracturing fluids, according to new research from The University of Texas at Austin. None of the quakes identified in the two-year study…

After successfully reentering the wellhead 4.3 miles below the ship, we began drilling towards the fault that unleashed the 2011 Tohoku earthquake and tsunami.

How do you insert a drill bit into a 20-inch well head 7 kilometers below your ship? Read Patrick Fulton’s second post from aboard the drill ship Chikyu near Japan.

Greetings from the scientific deep sea drilling vessel Chikyu. Our focus is to quickly drill into and study the fault that caused the March 2011 Japan Earthquake and tsunami.
