Abstract. 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.

Earthquake Lights

Because it is a newer and unproven technique, ionospheric seismology is still accepted as a phenomenon by a lot of scientists. However, research in this subject is rapidly increasing in the last decade. According to the ionospheric seismology, the mechanical energy accumulated by the compression of the rocks before the big earthquakes is released from the ground by creating a positive hall. These processes at the ground-to-air interface can lead to the injection of massive amounts of air ions into the lower atmosphere [1]. As a result of the injection, the earthquake lights, temperature rising, the pressure in the troposphere, radio frequencies distortions, and total electron content perturbation in ionosphere occur. Therefore, even if it does not enough alone, this parameter can be contributing to earthquake predict. It has been supported with several instances of manuscript. In this study, ionospheric total electron content was calculated for each station and satellite using GPS stations data in California, USA, for three last earthquakes. The earthquakes are named Hector Mine-1999, Baja-2009, and Napa-2014, and their magnitudes are 7.1, 7.2, and 6, respectively. After the processes, quite significant outcomes have been obtained.
