Information - SM11 Sun-earth connection triggers Earthquakes
Event Information
It has been observed that before the occurrence of an earthquake anomalous change in various environmental parameters of the Earth. These parameters include thermosphere, ionosphere, atmosphere and lithosphere in space and time. Correlation of changes in sunspots, star spots with the heliophysical , sun-earth environment and other cosmic activities and its influence on the earth are being studied since several years. It has been observed that some geo-physical parameter eg., Kp (planetary indices) and E-flux (electron flux) changes after the coronal mass ejection from the outer periphery of the sunspots. When the Kp (planetary indices) and E-flux (electron flux) changes suddenly it affects the environment of the earth. This phenomenon changes the thermosphere ionosphere atmosphere and lithosphere locally as well as globally. The response of the magnetosphere to interplanetary shocks or pressure pulses can result in sudden injections of energetic particles into the inner magnetosphere. It has been recorded that 36 hours before the occurrence of earthquake Kp values and E-flux increases drastically. After this increase sudden fall in Kp and E-fflux has been noticed before the earthquake and tsunami. The phenomenon was recorded before the Pakistan earthquake of 8th October 2005, Iran earthquake of 23rd February 2005,Sumatra earthquake on 26th December 2004 and Gujarat earthquake of 26th January 2001. Similar observations were recorded in other parts of the world. Deleneation of active faults by seismic microzonation coupled with sunspot activity studies has the proven potential for the triggering of an earthquake in space and time.
