Influence of seismic activity in the atmospheric electrical field in Lisbon (Po...
Silva, Hugo; Serrano, Cláudia; Reis, Heitor; Bezzeghoud, Mourad; Rosa, Rui; Borges, José; Caldeira, Bento; Tlemçani, M.; Biagi, F.The atmospheric electric field (AEF) can be influenced by different factors like cosmic radiation, radioactivity and aerosols [1]. Two innovative works have shown the possibility of enhanced air ionization, with consequent AEF perturbations, in the preparatory stage of earthquakes (EQ): Freund et al. [2] base their arguments on charge separation generated in the stressed volume followed by positive charges flow...
Supressão do Campo Eléctrico Atmosférico aquando do sismo de Sousel, M = 4.1
Silva, Hugo; Serrano, Cláudia; Reis, Heitor; Bezzeghoud, Mourad; Rosa, Rui; Borges, José; Caldeira, Bento; Tlemçani, M.In recent years different phenomena associated with seismic events have been referred in the literature. These include: unusual ultra-low-frequency electromagnetic emissions; anomalies in radio transmissions; variation of the ionosphere total electron content; and anomalous levels of different geochemical elements (in particular radon) in the earthquake preparation zone. Recent works shown the possibility of en...
