A pennanent geomagnetic observatory is always the ideal reference station for monitoring geomagnetic activity during airborne, marine or ground magnetic surveying, especially in Antarctica, where logi...
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...
Short time scale laws in self-potentialsignals from two different seismically active Mediterranean areas(the Southern Apennine chainand Crete Island)
self-potential earthquake prediction structural analysis anomalous diffusion
2015/9/28
Self-potential time series are investigated to characterise self-potential time scales. The data analysed were recorded in stations located in two active seismic areas of the Mediterranean region, the...
Self-potential chenges associated with volcanic activity:Short-term signals associated with March 9,1998 eruption on La Fournaise volcano (Reunion Island)
self-potential electric precursor ULF band self-potential mapping eruption
2015/9/28
After six years of quietness La Fournaise volcano entered into activity on March 9, 1998. Fissures opened gradually downwards on the northern flank of the cone. Two cones, Kapor and Krafft built, from...
Investigating the time dynamics of geoelectrical signals measured in two seismotectonic environments in the Mediterranean region: the Southern Apennine chain (Southern Italy) and the Hellenic arc (Crete Island, Greece)
