Magnetotelluric investigations of the seismically active region of Northwest Bohemia: preliminary results
Magnetotelluric seismic area Bohemia
2015/10/8
During 1997, within the framework of an Italian-funded scientific cooperation between Italy and the Czech Republic, a series of magnetotelluric (MT) soundings was carried out in the region of Northwes...
Maximum entropy estimation of values at Mt. Etna: comparison with conventional least squares and maximum likelihood results and correlation with volcanic activity
frequency-magnitude distribution maximim entropy method Mt. Etna
2015/10/8
The variations of the b coefficient in the frequency-magnitude relationship for earthquakes which occurred at Mt. Etna from 01/01/90 to 31/12/92 are analyzed; the completeness threshold for our earthq...
Displacement pattern of the Sinai area: first results from GPS
Sinai Gulf of Suez Aqaba-Levant fault GPS displacements
2015/10/8
A network of 12 GPS stations, seven of them located on the Sinai peninsula, another four on the west shore of the Gulf of Suez and the last on the inner Gulf of Aqaba (ELAT, Israel) was analyzed twice...
Some preliminary results of a worldwide seismicity estimation: a case study of seismic hazard evaluation in South America
Seismicity maximum observed magnitude seismic moment seismic momente rate
2015/9/30
Global data have been widely used for seismicity and seismic hazard assessment by seismologists. In the present study we evaluate worldwide seismicity in terms of maps of maximum observed magnitude (M...
The spectrum of thermally stimulated currents in rock samples from KTB drilling:preliminary results
thermally stimulated depolarization currents (TSDC) KTB drilling rocks relation parameters
2015/9/28
The technique of thermally stimulated depolarization currents (TSDC) was applied to fine grained amphibolite rock samples extracted from KTB drilling. Each sample was cooled down to liquid nitrogen te...
ANALYTICAL 3D VIEWS AND VIRTUAL GLOBES – PUTTING ANALYTICAL RESULTS INTO SPATIAL CONTEXT
Virtual globes information delivery analytical spatial information
2015/9/28
In this paper we are introducing analytical 3D views as a means for effective and understandable information delivery, using virtual
globes and the third dimension as an additional information carri...
Paleoearthquakes and slip rates of the North Tabriz Fault,NW Iran:preliminary results
active tectonics paleoseismology Iran Tabriz earthquake
2015/9/16
The North Tabriz Fault is a major seismogenic fault in NW Iran. The last damaging earthquakes on this fault occurred in 1721, rupturing the southeastern fault segment, and in 1780, rupturing the north...
Active tectonics and first paleoseismological results in Faial,Picoand S.Jorge islands (Azores,Portugal)
Azores neotectonics active faulting paleoseismology seismic hazard
2015/9/16
The neotectonics of the islands of Faial, Pico and S. Jorge (Azores) is presented. Preliminary paleoseismology data from trench exposures across three active fault zones (Lomba do Meio, Lagoa do Capit...
Palaeomagnetic results from an archaeological site near Rome (Italy): new insights for tectonic rotation during the last 0.5 Myr
palaeomagnetism block rotation active tectonics Rome
2015/9/15
Approximately 20 km north-east of Rome, along the modern trace of the Tiburtina road, recent archaeological diggings have brought to light a system of aqueduct galleries constructed by Roman engineers...
Results from the temporary installation of a small aperture seismic arrayin the Central Apenninesand its merits for local event detectionand location capabilities
seismic array beamforming f-kanalysis Central Apennines
2015/9/15
In order to evaluate the detection and localisation improvement of a small aperture array in the Northern Apennines, we installed an irregularly spaced test configuration in the vicinity of Città di C...
TEC and foF2 variations: preliminary results
ionospheric variability radio wave propagation space and satellite communications
2015/9/14
Investigation of the relationship between TEC and (foF2)2 shows that although they are highly correlated, a 玥ysteresis?effect exists between them. The slab thickness is greater before than after mid-d...
Self-oscillations in rocks,results of laboratory experiments
self-oscillations mechanoelectricself-oscillator transformations rocks
2015/9/14
The method of generation of self-oscillations in rocks is developed here. Self-oscillations arise as a result of direct and inverse mechanoelectric transformations without an external generator. Labor...
Results of gas flux records in the seismically active area of Val d'Agri (Southern Italy)
luids earthquakes methane gas emissions
2015/9/10
The Val d Agri area is well-known for oil exploration. An old 500 m deep exploration well in the northern part of
this area has been used for long-term hydrogeochemical investigations. The well is ch...
