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...
Tomographic analysis of self-potential data in a seismic area of Southern Italy
elf-potential tomographic technique fault system southern apennines
2015/9/28
The time and space anomalous behaviour of the Self-Potential (SP) field recorded in a seismic area of Southern Apennines, Italy, is discussed. The SP data were collected in the period June 1992-Novemb...
