Scientific efforts in the direction of successful Earthquake Prediction

Making a successful earthquake forecast is still one of the biggest challenges before the scientific community. Because the loss caused by the earthquakes alone is greater than the loss caused by any other natural calamity. Many attempts have been made from ancient times to predict seismic events, but success has not been achieved yet. Here we present a review of the studies which have been conducted in the past in the direction of making successful earthquake forecasts. We have touched upon those studies which come under the domain of seismoelectromagnetism and ionospheric perturbations. The various studies carried out in the past in this direction have made us believe that at least seismic precursors do exist although we have not been able to isolate a universal one.
