Seismic noise analysis with low-cost variable gain recorder
(2021)
This paper presents the design and implementation of a seismic noise analysis recorder. Specifically, the system has three main blocks. A configurable gain amplifier, a microcontroller for data acquisition and storage, and ...
Array analysis of the seismic wavefield of long-period events and volcanic tremor at Arenal volcano, Costa Rica
(2014-06-06)
We use wavefield decomposition methods (time domain cross correlation and frequency domain multiple-signal classification) to analyze seismic data recorded by a dense, small-aperture array located 2 km West of Arenal ...
Interpretation software applied to the evaluation of shallow seismic data processing routines in fluvial deposits
(Sociedade Brasileira de Geologia, 2019)
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 ...
Seismicity along the Magallanes-Fagnano fault system
(Elsevier, 2020)
The Magallanes-Fagnano fault (at similar to 51-56 degrees S) is a continental NW-SE transform fault zone that marks the boundary between the South American Plate (north) and the Scotia Plate (South). In 1949, two crustal ...
Stress field estimations for Colima volcano, Mexico, based on seismic data
(1999)
For first time, during 1991, seismic activity was recorded during an eruption at Colima volcano. We analyze these data to obtain a stress pattern using a composite focal mechanism technique. From the analysis of regional ...

Crustal seismicity in the Andean Precordillera of Argentina using seismic broadband data
(Elsevier Science, 2020-07)
In this study, we analyze 100 crustal Precordilleran earthquakes recorded in 2008 and 2009 by 52 broadbandseismic stations from the SIEMBRA and ESP, two temporary experiments deployed in the Pampeanflat slabregion, between ...
