Relationship between Variation of Total Ozone Concentration and Severe Geomagnetic Storms over Lagos in Nigeria (Published)

This paper investigates the relationship between total ozone concentration (TOC) and severe geomagnetic storm index (peak DST ≤ −100 nT) over Lagos (Geographic: 6.50N, 3.40E; dip: 6.90S), Nigeria, from 1997 to 2005. Analyses show that there is a significant and persistent response of total column ozone to severe geomagnetic storms. Severe geomagnetic storms can cause ozone concentration depletions or enhancements by amounts that could be up to 3 DU in the equatorial region. Positive variations of total column ozone occurred only in wet season, and under high solar activity maximum/East phase Quasi Biennial Oscillation (QBO) conditions. Furthermore, it was observed that the minimal variation of total column ozone response to major geomagnetic storms appears to be caused by changes in QBO, which is an important component of atmospheric dynamics in the equatorial stratospheric region. Invariably, this shows that changes of circulation pattern agree qualitatively with changes in total column ozone. Also, the seasonal variation of ozone (O3) column in the equatorial latitude (Lagos) followed a definite pattern, indicating maximum amplitude between July and September and minimum amplitude between December and February.

An Innovative Model to Predict Earthquakes in Indian Peninsula (Published)

Can earthquakes be predicted? So far, the answer is no. Scientists are unlikely to be ever able to predict earthquakes with any amount of certainty, according to the United States Geological Survey Apr 25, 2013. An Innovative Model for Earthquake Prediction (IMEP) proposed in this paper is a combination of Vedic Astrology (Vedānga), Varāha Mihira’s Brihat Samhita and scientific data of magnetic variations, structural geology such as fault zones, tectonic plates’ directions, loose soil areas of all the earthquakes occurred in Indian Peninsula shield over a period of 200 years. In the course of preparation of this paper, it is observed that the earthquakes occured at regular intervals of about 11 years and mostly during bright fortnight due to extraordinary astronomical phenomena occurring in the planets and special movements of the heavenly bodies. Vedānga and Brihat Samhita state that earthquakes are caused by eclipses of the luminaries. It is, therefore, plausible to predict earthquakes in a specific locality within a specific time limit utilising this model. However, as an initial step, the present model has been designed for application for India. The next earthquake in Indian peninsula is predicted to occur on Wednesday, the 16th March, 2016 on the basis of the proposed hypothesis model.
