| Zusammenfassung |
| The first photographs of Co-seismic Luminescence, commonly known as
Earthquake lights (EQLs), were reported in 1968 in Japan. However, there have been
documented reports of luminescence associated with earthquakes since ancient
times in different parts of the world. Besides this, there is modern scientific work
dealing with evidence of and models for the production of such lights. During
the Peru 15 August 2007 Mw=8.0 earthquake which occurred at 06:40 p.m. LT,
hence dark in the southern wintertime, several EQLs were observed along the
Peruvian coast and extensively reported in the capital city of Lima, about
150 km northwest of the epicenter. These lights were video-recorded by a
security camera installed at the Pontificia Universidad Catolica del Peru
(PUCP) campus and time-correlated with seismic ground accelerations
registered at the seismological station on campus, analyzed and related to
highly qualified eyewitness observations of the phenomena from other parts
of the city and to other video recordings. We believe the evidence presented
here contributes significantly to sustain the hypothesis that
electromagnetic phenomena related to seismic activity can occur, at least
during an earthquake. It is highly probable that continued research in
luminescence and the use of magnetometers in studying electromagnetic
activity and radon gas emanation detectors will contribute even more towards
determining their occurrence during and probably prior to seismic activity. |
