Rupture processes of the 2012 September 5 Mw 7.6 Nicoya, Costa Rica earthquake constrained by improved geodetic and seismological observations
(2015-08-17)
On 2012 September 5, the anticipated interplate thrust earthquake ruptured beneath the Nicoya peninsula in northwestern Costa Rica close to the Middle America trench, with a magnitude Mw 7.6. Extensive co-seismic observations ...
Comparison of Tree Species Sensitivity to High- and Low-Extreme Hydroclimatic Events
(2001-03)
We present here a six-species comparison of tree-ring growth response to
extremes (below the 30th and above the 70th percentile) in temperature, precipitation,
and corresponding streamflow. The species compared are Pinus ...
