Thermal neutrons’ response to the GLEs

Ultrasonic Piezonuclear Reactions in Steel and Sintered Ferrite Bars

“…[47][48][49] Recent evidences of neutron emissions in correspondence to earthquakes lead to consider also the Earth's Crust, in addition to cosmic rays, as being a relevant source of neutron flux variations. [20][21][22][23][24] Neutron emissions exceeded the neutron background up to 1000 times in correspondence to seismic events with a Richter magnitude equal to the 4th degree. 7 49 These measurements could be put in correlation with the evidence of iron depletion counterbalanced by the presence of lighter elements just in correspondence to seismic active areas of our planet.…”

“…[17][18][19] Very recently, in fact, neutron emissions during microseismic activity and before major earthquakes have been measured. [20][21][22][23][24] At the same time, anomalous chemical changes involving elements such as Fe, Ni, Al, Si, amd Mg may be recognized during the Earth's Crust evolution just in correspondence to periods characterized by the most intense tectonic activity. 18 19 From this point of view, it is also interesting to emphasize that anomalous phenomena such as iron and nickel depletions, [25][26][27][28] that have affected the geomechanical and geochemical evolution of the Earth's Crust, should be considered as an indirect evidence of piezonuclear reactions.…”
