The Transportable Array (TA) continues to roll eastward across the US. Having crossed the Mississippi River in March 2011, the TA will…
2011-12-22The global seismology community established a new model of international cooperation in response to the great Chile earthquake of February 27, 2010. The adaptable framework is geared to produce a high-quality, open-access data set of seismic waveforms col
2011-08-16In its July 2011 issue, Popular Science ranked EarthScope the “most epic” big science project because of its ambitious scope: Exploration of the deep geologic structure and evolution of an entire continent.
2011-03-22The San Andreas Fault (SAF) deforms by permanent creep and microseismicity in central California. Higher-thanhydrostatic fluid pressures, which could explain low strength and creep, were not detected during the San Andreas Fault Observatory at Depth (SAFO
2010-09-22GPS data collected as part of PBO, though, contain additional information that is very useful in ways unforeseen when the original PBO science plan was created.

2010-03-22As the USArray Transportable Array marches eastward, seismic images are providing ever more detailed insight into present day structures of the crust and mantle beneath North America. But how old are these structures and what do they tell us about the geo
