### Correlation of triggering of earthquakes with CME:
The occurrence of lights during earthquakes may be explained by the sunspot activities during solar maximum. The Earth has a magnetic field with north and south poles. The magnetic field of the earth is surrounded in a region called the magnetosphere. The magnetosphere prevents most of the particles from the sun, carried in solar wind from hitting the earth. Some particles from the solar wind can enter the magnetosphere. The particles that enter from the magnetotail travel toward the Earth and create the aurora oval light shows. Dangerous particles are not able to penetrate to the Earth's surface but are forced by the magnetic field to move around the Earth. Particles gain entry through the cusps that are shaped like funnels over the polar regions or they gain entry far downstream from the Earth. The particles that enter downstream travel toward the Earth and are accelerated into the high-latitude ionosphere and produce the auroral oval light shows. Since the most intense auroras occur at solar maximum, it was once thought that the Sun hurled material out during these raised times of solar activity and that that material funneled directly into the polar cusps. However, we now understand that the electrons that cause the auroras come in downstream or from the Earth's magnetic tail. These electrons that enter at the magnetotail are energized locally within the magnetosphere. The solar wind, emanating from the Sun, injects plasma into the magnetosphere and transfers energy to it. Several times a day, the magnetosphere undergoes a disturbance called a substorm. As the substorm grows, most of the solar wind energy is dissipated within the magnetosphere, ionosphere and upper atmosphere. This disturbance ultimately causes auroral displays, the acceleration of charged particles to high energies, the emission of intense plasma waves and electromagnetic waves, and the generation of strong ionospheric currents that produce significant changes in the upper atmosphere. These waves and currents often result in severe problems on Earth with communications, power supplies, and spacecraft electronics. Other higher energy particle radiation that could pose a danger to life here on Earth is forced to drift around the Earth within two large donut-shaped regions called the radiation belts. Invisible magnetic fields are the reason that particle radiation moves in this way. Before the occurrence of the catastrophic earthquake on 26 th January 2001 at Kutch, IMAGE spacecraft captured an invisible magnetic tail at Gujarat, India. This is a major precursor of the earthquake. More advanced researches should be conducted to identify the geolatitude-longitude which is likely to be affected by the magnetic tail, which may trigger earthquakes in active fault areas. A sudden rise in electron flux and planetary indices 36 hrs before 26 th January 2001 earthquake of Kutch, (Gujarat, India) and its sudden fall before the occurrence of earthquake was observed. Similar observations were made in several other cases also including the Andaman Islands. Coronal Mass Ejection, increase in Kp values (more than 4), sudden increase in Kp indices and electron flux can be forewarning of seismic disturbance in earthquake prone active fault areas and other environmental changes of earth. On 24 th January 2001 an Earth directed coronal mass was ejected, which took two days to reach the earth's surface and may have triggered the active fault in the Katrol Formation of Kutch to produce a major earthquake of magnitude 7.9 in Gujarat, west coast of India. This area was reported as seismically active. In the entire world, a total of 65 earthquakes have been reported on the same day. Earth directed Coronal Mass Ejection produced a suspected invisible tail of electrified gas. IMAGE spacecraft spotted the tail, which streams from earth towards Sun. The region laced by earth's magnetic field, called the magnetosphere, dominates the behavior of electrically charged particles in space near earth and shields our planet from the solar wind.
