Earthquake Prediction is the ultimate goal for geoscientists. This volume presents the latest ideas of the ever fascinating and challenging research of earthquake prediction. Sunspot activity and Coronal mass ejection are considered to be influential phenomena in affecting both the electric as well as the magnetic characteristics of sun-earth environment. All these changes have been observed before the occurrence of earthquakes and tsunami in various parts of the earth.A session on Earthquake Prediction, chaired by Dr. Saumitra Mukerjee was held during the European Geosciences Union General Assembly 2005, (Vienna, Austria, April 2005). The EGU General Assembly was able to bring together 8000 geoscientists from all over Europe and the rest of the world into one meeting covering all disciplines of the Earth and Planetary Sciences. This book presents the 7 papers presented in the session on Earthquake Prediction.
