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...

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...
A comparison of f0F hmE model calculations with El Arenosillo digisonde observations. Seasonal variations
Ionospheric E-layer-theoretical modeling solar EUV nitric oxide
2015/10/8
Seasonal variations of hmE and f0F2 are analyzed using El Arenosillo digisonde observations during solar minimum (1995-1996). Unlike some widely used empirical models daytime hmE show seasonal variati...

The INGV tectonomagnetic network in central Italy. Fifteen years of observations and future developments: an update
geomagnetic field earthquakes
2015/9/1
Tectonic events, as earthquakes and volcanic eruptions, may generate variations in the local geomagnetic field intensity. To detect possible effects related to seismic activity in central Italy, the I...
