### Correlation of triggering of earthquakes with CME:  
In recent years, earthquake prediction has moved from being a guessing game to more of a science. The primary obstacle to understanding earthquakes was geologists' refusal to accept the concept of tectonic plate movement (continental drift). Today we know that the crust of the Earth does float on a \"sea\" of magma, and that earthquakes and volcanism occur primarily in those zones where one plate is rubbing against another - \"fault lines\". This model is not perfect because there are often \"rogue\" quakes which strike in unexpected areas, but it works extraordinarily well. Nonetheless, there are certain aspects of earthquakes that lend themselves to predicting their incidence. One factor is that oscillations in the planet's magnetic field often occur right before quakes; these oscillations, as noted above, often correlate strongly with astronomical and solar events. But geologists are afraid to say something ridiculous along the lines of \"sunspots cause earthquakes\", despite the fact that, in a certain sense, they do... radio wave propagation (e.g. ionospheric \"whistlers\"), which appears to play a role in earthquakes, and it can be studied by closely monitoring the impact of the solar wind on the ionosphere. We are interested in the sun because of the many influences it has on our lives and our environment. Beyond the obvious considerations of heat and light, some examples of these direct and indirect solar influences are the effects on short-wave radio communications, navigation, use of satellites for communication and navigation, hazards to humans and instruments in space, electrical power transmission, geomagnetic prospecting, gas pipeline monitoring, and possibly weather, seismotectonics and human and animal behavior. The Solar maximum has come again after 2000. It has been noticed that the number of sunspots are continuously on the rise. Earth directed Coronal Mass Ejections (CME) were very frequent during 2000-2002 (Figure.1). Continuous impact of the tremendous amount of energy has frequently changed the Kp (planetary indices), and free electrons in the upper part of the atmosphere. These changes in Sun-Earth environment induced by the Sun have changed the geo-sphere and atmosphere from time to time. Occurrence of earthquakes followed by CME and raised Kp values have sufficient bearing on this hypothesis. All these facts compelled us to rethink and reopen the possible researches in the Sun-Earth environment. Different types of earthquake lights have been reported before, during and after severe earthquakes. Some observers have seen red, blue or white glows, while others have described them as balls of fire or flashes from the sky. Such observations have been assigned different causes. Some attribute them to the lightning from a thundercloud; some to sparks in the electric power lines; while others to the generation of static electricity in the vicinity of the focal zone of earthquakes where relative movements of rocks may produce heat and light. Over the sea, such light could arise from luminous marine organisms excited by the vibrations produced by the earthquakes [35]. Earthquake lights have been reported before the Matsushiro swarms during the year 1965 to 1967 and before some recent earthquakes in China. During the Pattan earthquake (Pakistan) of December 1974, reliable forest officers and doctors far away from the earthquake epicenter observed earthquake lights coming from the sky. Before the occurrence of the Jabalpur earthquake (India) of 1997 a light source came from the sky before the occurrence of the earthquake [35]. Experiments have been conducted at the University of Western Ontario, London (Canada) to understand the possible mechanism of earthquake lights. It has been suggested that adsorption of condensation of water could be thought of as an energy source for the release of light from solid particles suspended in a cooling column of air above ground. But this theory could not explain the occurrence of light from the sky.
