The Nicoya segment of Middle American Trench: an Excellent Target for Drilling and Monitoring the Shallow Portion of the Seismogenic Zone
(2011-06-28)
The Nicoya segment of Middle America Trench has generated large earthquakes in 1883, 1900 and 1950. Since the Nicoya peninsula sits right over the seismogenic zone, it has proved to be a unique site for near field monitoring ...
Combined GPS, EDM and triangulation surveys of the rapid downslope motion of the western flank of Arenal Volcano, Costa Rica
(2011)
Here we present initial conclusions of a one year-long combined geodesy campaign on Arenal Volcano, in Costa Rica (2008-2009). Our data shows evidence for an active local tectonic surrounding, and a 7cm/yr displacement ...
Spatial shifts in fumarolic degassing at Poás volcano: Phreatic Activity in the Ultra Acid Crater Lake versus Subaerial Degassing
(IAVCEI Commission on Hazards and Risk, 2011-09-11)
Summary of the presentation Spatial shifts in fumarolic degassing at Poás volcano: Phreatic Activity in the Ultra Acid Crater Lake versus Subaerial Degassing
Coda wave attenuation in the Parecis Basin, Amazon Craton, Brazil: sensitivity to basement depth
(Springer, 2011)
Small local earthquakes from two aftershock sequences in Porto dos Gaúchos, Amazon
craton—Brazil, were used to estimate the coda wave attenuation in the frequency band of 1 to 24 Hz. The time-domain coda-decay method of ...
