Analysis of dynamics of vulcanian activity of Ubinas volcano, using multicomponent seismic antennas
(Elsevier, 2014-01-15)
A series of 16 vulcanian explosions occurred at Ubinas volcano between May 24 and June 14, 2009. The intervals between explosions were from 2.1 h to more than 6 days (mean interval, 33 h). Considering only the first nine ...
Automatic classification of volcano seismic signatures
(American Geophysical Union, 2018-12)
The prediction of volcanic eruptions and the evaluation of associated risks remain a timely and unresolved issue. This paper presents a method to automatically classify seismic events linked to volcanic activity. As increased ...
Time-lapse critical reflection: does it really work in seismic monitoring of low porosity and high effective stress conditions?

Seismic Spectral Monitoring of CO2 in a Geological Reservoir
(Asociación Argentina de Mecánica Computacional, 2013-11)
Peak frequency is a spectral seismic attribute widely used for reservoir thickness estimation and hydrocarbon detection. In this work we apply this attribute in the context of the geological storage of carbon dioxide (CO2) ...
AVA seismic reflectivity analysis in carbon dioxide accumulations: Sensitivity to CO2 phase and saturation
(Elsevier Science, 2011-02)
Seismic monitoring of sequestered carbon dioxide (CO2) in underground deposits is a matter of growing importance. The subsurface monitoring of this greenhouse gas is possible due to the marked contrast between the physical ...
Inspection of Seismic Damage and Conservation Conditions in Modern School Buildings in Chile
(Springer Netherlands, 2019)
The present study describes the procedures and results of inspections carried out in public school buildings constructed in Chile between the 40s and 80s. These buildings constitute part of the country’s modern heritage. ...
