“…In agreement with a previous work (Sgrigna et al, 2005), the daily averages of CRs were calculated according to their invariants coordinates. In addition, we also considered the geomagnetic field B at the satellite locations.…”

“…Experimental data on high-energy charged particle fluxes, obtained from various near-Earth space experiments (MIR orbital station, METEOR-3, GAMMA and SAMPEX satellites) were processed and analyzed; a 2 to 5 h precursor effect resulted (Aleksandrin et al, 2003), although its statistical significance was somewhat limited. A re-analysis of the SAM-PEX database also shows a 4 h precursor effect (Sgrigna et al, 2005). The case study of HF wave measurements and gamma rays diagnostic performed on board the CORONAS-I satellite have shown a possible correlation between enhancements of whistler wave activity and soft gamma ray fluxes related to seismic activity (Rothkaehl et al, 2006).…”

“…Our data analysis started from a selection of PBs from the NOAA database. Our analysis method follow the strategy introduced by Sgrigna et al (2005) but implements some differences. These differences were necessary because, compared to the previously published experiments, NOAA satellites operate at higher orbits and covers different energy range intervals.…”

Abstract.A decade of NOAA-15 particle flux data offers an opportunity to test claims of correlations between seismic activity and effects on the ionosphere. Over the last two decades, potentially interesting observations in the ionosphere-magnetosphere transition region have been investigated. Specifically these consists of anomalous particle fluxes detected by several space experiments and correlated with the earthquake occurrence. These particle fluxes are characterised by anomalous short-term and sharp increases in high energy particle counting rates, referred to as particle bursts. In this work, more general rules for particle bursts selection have been defined and tested on the NOAA database, for particles inside and outside the South Atlantic Anomaly region. The whole period of ten years burst activity from NOAA-15 database is reported. Data from four satellites, NOAA-15, 16, 17 and 18, were analyzed during periods of solar quiet activity in connection with strong earthquakes, revealing presence of bursts detected on more than one satellite close to the time of the same seismic events. This preliminary study presented here concentrates on periods of major Indonesian earthquakes from 1998 to date, including Sumatra event M=9, during which geomagnetic Ap index was less than 16 and with no sudden ionospheric disturbances. During this period particle burst temporal distributions have shown some correspondence with earthquake times. The limits of the analysis presented in this papers are discussed as well as prospects for future work.

“…Experimental data on fluxes of electrons with energy from few to hundreds of MeV, obtained from four near-Earth space detectors (MIR orbital station, METEOR-3, GAMMA and SAMPEX satellites) were analyzed statistically and resulted in a 2-5 hours precursor effect. Recently, a more detailed re-analysis of the SAMPEX database also showed a 4 hours precursor effect (Sgrigna et al 2005). Previous studies show that sub-MeV electron precipitations can be caused by several sources of electromagnetic waves.…”

A new method to study a possible temporal correlation between hundreds of keV Van Allen Belt electrons and strong earthquakes is proposed. It consists in measuring the electrons pitch angle distribution (PAD), searching for PAD disturbances and studying the time correlation between these PAD disturbances and strong earthquakes, occurring within a defined time window. The method was applied to measurements of energetic electrons, which were performed with the ECT-MagEIS detector on board of the Van Allen Probes mission and strong continental earthquakes, with M 5.0 and hypocenter depth 100 km. We report the correlation studies for electrons with energies of ∼350 keV, with which a 3.84 standard deviations correlation peak was found at +[0, 3]h time bin, and ∼450 keV with which no correlation peaks above 2.0 standard deviations were found. Our work proves the feasibility of the proposed method and the obtained results add useful and additional information with respect to past studies.

“…Among the possible phenomena generated by an earthquake, bursts of Van Allen belt electron fluxes in the magnetosphere have been repeatedly reported in literature by various experiments, though a statistical significance was always difficult to claim [1][2][3]. The CSES mission aims at measuring such particle bursts, by means of the High Energy Particle Detector (HEPD).…”

The China Seismo Electromagnetic Satellite (CSES) aims to contribute to the monitoring of earthquakes from space. This space mission, lead by a Chinese-Italian collaboration, will study phenomena of electromagnetic nature and their correlation with the geophysical activity. The satellite will be launched in 2017 and will host several instruments onboard: two magnetometers, an electrical field detector, a plasma analyzer, a Langmiur probe and the High Energy Particle Detector (HEPD). The HEPD, built by the Italian collaboration, will study the temporal stability of the inner Van Allen radiation belts, investigating precipitation of trapped particles induced by magnetospheric, ionosferic and tropospheric electromagnetic emissions, as well as by seismo-electromagnetic disturbances. It consists of two layers of plastic scintillators for trigger and a calorimeter. The direction of the incident particle is provided by two planes of double-side silicon microstrip detectors. HEPD is capable of separating electrons and protons and identify nuclei up to Iron. The HEPD will study the low energy component of cosmic rays too. The HEPD comprises the following subsystems: detector, electronics, power supply and mechanics. The electronics can be divided in three blocks: silicon detector, scintillator detectors (trigger, energy and veto detectors) and global control and data managing. In this paper a description of the electronics of the HEPD and its main characteristics will be presented.
