Discovery of hidden earthquake presents challenge to earthquake early-warning systems
Seismologists at the University of Liverpool studying the 2011 Chile earthquake have discovered a previously undetected earthquake which took place seconds after the initial rupture.  View News Article (2015-11-17)

U of M researchers unlock mystery of layer encircling the Earth's core
University of Minnesota associate professor of chemical engineering Renata Wentzcovitch and her team of researchers have confirmed the properties of a mineral (post-perovskite) that may form near the Earth's core in a layer called the D'' region. View News Article (2006-01-31)

Russian Far East holds seismic hazards that could threaten Pacific Basin
For decades, a source of powerful earthquakes and volcanic activity on the Pacific Rim was shrouded in secrecy, as the Soviet government kept outsiders away from what is now referred to as the Russian Far East. View News Article (2012-12-04)

New findings indicate sediment composition affected the strength of Sumatran earthquake
Sumatra experiences frequent seismic activity because it is located near the boundary of two of Earth's tectonic plates. Earthquakes occur at 'subduction zones,' such as the one west of Indonesia, when one tectonic plate is forced under another--or subducts. View News Article (2010-07-09)

Critically endangered whales flee Russian oil, gas boom
Russian oil and gas company Rosneft is conducting oil and gas exploration work that may have caused the critically endangered western gray whale to flee its main feeding ground.  View News Article (2010-09-07)

Scientists use seismic waves to locate missing rock under Tibet
Geologists at the University of Illinois at Urbana-Champaign have located a huge chunk of Earth's lithosphere that went missing 15 million years ago. By finding the massive block of errant rock beneath Tibet, the researchers are helping solve a long-standing mystery, and clarifying how continents behave when they collide. View News Article (2007-02-08)

San Andreas affected by 2004 Sumatran quake
U.S. seismologists have found evidence that the massive 2004 earthquake that triggered killer tsunamis throughout the Indian Ocean weakened at least a portion of California's famed San Andreas Fault. View News Article (2009-10-01)

Earthquake in Chile -- a complicated fracture
The extremely strong earthquake in Chile on 27 February this year was a complicated rupture process, as scientists from the GFZ German Research Centre for Geosciences found out. Quakes with such magnitude virtually penetrate the entire Earth's crust. View News Article (2010-03-10)

Double jeopardy: Building codes may underestimate risks due to multiple hazards
As large parts of the nation recover from nature's one-two punch-an earthquake followed by Hurricane Irene-building researchers from the National Institute of Standards and Technology (NIST) warn that a double whammy of seismic and wind hazards can increase the risk of structural damage to as much as twice the level implied in building codes. View News Article (2011-09-14)

Ground movement risks identified by Terrafirma
Ground movements are responsible for hundreds of deaths and billions of Euros annually, and the threat they pose is increasing due to urbanisation and land use. ESA's GMES Service Element Programme is backing a project, Terrafirma, to help mitigate these risks. View News Article (2006-09-11)
