2004 Oregon Quakes in 'Locked' Area of Tectonic Plate Boundary

 

Two modest earthquake clusters off the Oregon coast in 2004 may be more significant than scientists initially realized after detailed analysis of the main shocks. Researchers are setting up a temporary onshore/offshore seismic array to get more data about the nature of the boundary between the North American and Juan de Fuca plates.

Looking Inside a Volcano's Magma Chamber

 

El Misti volcano looms over the modern city of Arequipa, Peru. Two thousand years ago, it erupted explosively, depositing ash and lavas in a layer tens of meters thick. Frank Tepley examines rocks blasted out of the magma chamber from that eruption, to begin to improve predictions of future eruptions.

    Three OSU Oceanographers Named AGU Fellows

     

    AGU is an international scientific organization, focusing on the understanding of the Earth and space including the fiields of geology, oceanography, atmospheric sciences, volcanism, seismology, and others. Acceptance as AGU fellows is restricted to fewer than one-tenth of 1 percent of its members. Selected from OSU were Dudley Chelton, Robert Duncan and Anne Tréhu.

    OSU Teams with Woods Hole, Scripps on Ocean Observatories Initiative

     

    Oregon State University will receive $20.6 million over the next six years to lead a component of the National Science Foundation’s Ocean Observatories Initiative that will be located in the Pacific Northwest’s coastal ocean.
