Best-basis analysis of broadband tremor signals
adaptive spectrogram analysis broadband tremor
2015/10/8
Active volcanoes usually generate highly non-stationary broadband tremor signals. Short-time shock events with a frequency content of several decades are superimposed on a stationary narrow band conti...
Spectrogram analysis of selected tremor signals using short-time Fourier transform and continuous wavelet transform
spectrogram wavelet transform broadband tremor
2015/10/8
Among a variety of spectrogram methods Short-Time Fourier Transform (STFT) and Continuous Wavelet Transform (CWT) were selected to analyse transients in non-stationary tremor signals. Depending on the...
Dynamical tools for the analysis of long term evolution of volcanic tremor at Stromboli
non linear analysis volcano trtemor state space reconstruction delayed coordinates
2015/10/8
Stromboli is characterized by persistent seismic activity, both in terms of tremor and of discrete events associated with moderate explosions defining the so-called "Strombolian activity". This kind o...
Volcanic tremor associated with eruptive activity at Bromo volcano
volcanic tremor broadband seismology
2015/10/8
Three broadband stations were deployed on Bromo volcano, Indonesia, from September to December 1995. The analysis of the seismograms shows that the signals produced by the volcanic sources cover the f...
Listening carefully: unique observations of harmonic tremor at Lascar volcano, Chile
volcano seismology harmonic tremor
2015/10/8
During the deployment of Proyecto de Investigación Sismológica de la Cordillera Occidental 94 (PISCO'94) in the Atacama Desert of Northern Chile, a broadband seismic station and a network of three sho...
Observations of two special kinds of tremor at Galeras volcano, Colombia(1989-1991)
Galeras volcano harmonic tremor spasmodic tremor degassing activity resonance crack
2015/10/8
Since the reactivation of Galeras volcano in 1988 its seismic activity has been dominated by a variety of LP waveforms and tremor events. Some of these signals occurred as a response to volcanic activ...
Observations of volcanic earthquakes and tremor at Deception Island - Antarctica
volcanic earthquakes tremor antartica
2015/10/8
Deception Island - South Shetlands, Antarctica is site of active volcanism. Since 1988 field surveys have been carried out with the aim of seismic monitoring, and in 1994 a seismic array was set up ne...
Slow earthquakes and low frequency tremor along the Apennines,Italy
Slow earthquakes Tremor Apennines
2015/9/1
This paper reviews the main observations on slow earthquakes and low frequency tremor made along the Apennines,the main seismic active zone of Italy. These observations have been made using a geodetic...
The role of velocity-neutral creep on the modulation of tectonic tremor activity by periodic loading
velocity-neutral creep on the modulation tectonic tremor activity periodic loading
2014/4/15
Slow slip events and associated non-volcanic tremors are sensitive to oscillatory stress perturbations, such as those induced by tides or seismic surface waves. Slow slip events and tremors are though...
The 2006 slow slip event and nonvolcanic tremor in the Mexican subduction zone
slow slip events non volcanic tremor in the Mexican subduction zone
2014/4/10
The last decade featured an explosive sequence of discoveries of slow slip events (SSE) and nonvolcanic tremor(NVT) in different subduction zones and continental faults.Many observations show that SSE...

Statistical analysis of Stromboli VLP tremor in the band [0.1–0.5] Hz:some consequences for vibrating structures
Statistical analysis Stromboli VLP tremor band [0.1–0.5] Hz vibrating structures
2009/11/9
We analyze time series of Strombolian volcanic tremor, focusing our attention on the frequency band [0.1–0.5] Hz (very long period (VLP) tremor). Although this frequency band is largely affected by no...
Tremor is a well-recognized manifestation of the high pressure nervous syndrome (HPNS). As such, its measurement and analysis during deep hyperbaric exposures can be an important index of central nerv...
