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...
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...
A method for f0F2 monitoring over Spain using the El Arenosillo digisonde current observations
Ionospheric F2 layer short-term prediction methods ionospheric mapping
2015/10/8
Ionosphere monitoring implies: observations, prediction and mapping of ionospheric parameters. A case with one available (El Arenosillo) ionosonde is considered. Some statistical methods for f0F2 shor...
The Friuli (NE-Italy) tilt/strain gauges and short term observations
tiltmeter strainmeter short term observations
2015/10/8
The tilt/strainmeter network of the Department of Earth Sciences of the University of Trieste, has by now a long history of records, the Trieste Grotta Gigante horizontal pendulum station having been ...
Mapping plasma structures in the high-latitude ionosphere using beacon satellite, incoherent scatter radar and ground-based magnetometer observations
Beacon satellites ionospheric plasma
2015/9/25
In the autumn of the year 2000, four radio receivers capable of tracking various beacon satellites were set up along the southwestern coast of Greenland. They are used to reconstruct images of the ion...
A revised method to extract thermospheric parameters from incoherent scatter observations
thermospheric ionization
2015/9/14
Height distribution of ionospheric plasma parameters in the F2-region is closely related to height distribution of the main thermospheric parameters. Therefore, they can be extracted from ionospheric ...
Numerical 2D modeling of site responsein Dinar Graben, Southwest Turkey,and comparison with observations
2D modeling basin edge effect Dinar site response
2015/9/10
The October 1, 1995 Dinar earthquake (ML=5.9) caused extensive damage within a limited area in Dinar town located
in southwestern Turkey. Graben structure of the damaged area suggests the basin edge ...
Deep seafloor magnetic observations under GEOSTAR project
GEOSTAR project Tyrrhenian sea Magnetic observation
2015/9/7
Performing good quality magnetic observations is not an easy task; making them in the extreme marine environment is even much more challenging. The European funded GEOSTAR project succeeded in reachin...
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...
