'Caldas Tear' Resolves Seismic Activity Beneath Colombia
2013-06-06 20:49:15

Seismological Society of America Colombia sits atop a complex geological area where three tectonic plates are interacting, producing seismicity patterns that have puzzled seismologists for years. Now seismologists have identified the "Caldas tear," which is a break in a slab that separates two subducting plates and accounts for curious features, including a "nest" of seismic activity beneath east-central Colombia and high grade mineral deposits on the surface. In a paper published in...

An ocean mapping expedition has shed new light on deepest place on Earth, the 2,500-kilometer long Mariana Trench in the western Pacific Ocean near Guam. Using a multibeam echo sounder, state-of-the-art equipment for mapping the ocean floor, scientists from the University of New Hampshire Center for Coastal and Ocean Mapping/Joint Hydrographic Center found four “bridges” spanning the trench and measured its deepest point with greater precision than ever before. Research...

The Center for Coastal and Ocean Mapping (CCOM) has mapped the deepest part of the ocean in greater detail than ever before. The scientists mapped the Mariana Trench in the western Pacific, which runs about 1,550 miles and extends down to nearly seven miles. The deepest point measured extends deeper below sea level than the height of Mount Everest, which is the highest point on the Earth. "We mapped the entire trench, from its northern end at Dutton Ridge, all the way to where it...

A peculiar swarm of earthquakes have been occurring off of Oregon's central coast, resembling those that happen just prior to a volcanic eruption. However, scientists are baffled as there are no volcanoes in the area.  There have been more than 600 quakes during the past 10 days in an area 150 miles southwest of Newport. The largest quake was a magnitude of 5.4, with two others measuring greater than magnitude 5.0, OSU reported.Few of the quakes have been strong enough to be felt on...
