| Zusammenfassung |
| 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. |
