Broadband waveforms and site effects at a borehole seismometer in the Po alluvial basin (Italy)
broadband data borehole seismometer site effect alluvial basin
2015/9/28
Broadband seismograms recorded at a borehole three-component (high dynamic range) seismic station in the Po Valley (Northern Italy) were analyzed to study the velocity structure of the shallow sedimen...
Deep-sea borehole seismological observatories in the western Pacific: temporal variation of seismic noise level and event detection
deep-sea borehole observatory broadband seismometer seismic noise level
2015/9/7
Seismological networks provide critical data for better understanding the dynamics of the Earth; however, a great limitation on existing networks is the uneven distribution of stations. In order to ac...
Drag-out effect of piezomagnetic signals due to a borehole:the Mogi source as an example
piezomagnetic effect borehole magnetic measurement the Mogi model Long Valley
2015/9/2
We show that using borehole measurements in tectonomagnetic experiments allows enhancement of the observed signals. New magnetic dipoles, which vary with stress changes from mechanical sources, are pr...
Variations in geoacoustic emissions in a deep borehole and its correlation with seismicity
geoacoustic emission deep borehole diurnal variation
2015/9/1
Continuous geoacoustic emission (GAE) measurements were acquired using a three-component geophone
placed in a borehole at a depth of near 1000 m at Petropavlovsk-Kamchatsky starting in August 2000. U...
Formation of a laccolith by magma pulses: Evidence from modal and chemical composition of the 500 m long borehole section through the Permo-Carboniferous Landsberg laccolith (Halle Volcanic Complex)
laccolith formation magma pulses rhyolite Halle Volcanic Complex

The 500 m long section through the upper part of the Permo-Carboniferous Landsberg laccolith (Halle Volcanic Complex)
was sampled every 25 meters. The modal proportions between plagioclase and K-feld...
Hydrocarbon Volumetric Analysis Using Seismic and Borehole Data over Umoru Field, Niger Delta-Nigeria
Hydrocarbon Reservoir Bright and Dim Spots Well-to-Seismic
2013/3/6
Wireline signatures were used to identify hydrocarbon bearing sands and evaluate Petrophysical parameters for hydrocarbon pore volume determination. Well to seismic tie revealed that these reservoirs ...
Temporal and spatial changes of radon concentration in borehole water
Temporal spatial changes radon concentration borehole water
2010/10/21
The 222Rn activity concentration in ground water from four boreholes was investigated from January 2006 to June 2008. The boreholes are situated in the region of the Astronomical and Geophysical Obser...
