1. DEVELOPMENT OF MODELS FOR RATING SEISMIC ACTIVITIES USING RADIATED ENERGY OF EARTHQUAKES

71 Student Researchers

Earthquakes

An earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves. The energy released during an earthquake could be in the form of elastic strain energy, gravitational potential energy or chemical energy. Of all these, the release of elastic strain is the most important cause, because this form of energy is the only kind that can be stored in sufficient quantity in the Earth to produce major disturbances. Eart...

4. ASSESSMENT OF GNSS-BASED INTEGRATED WATER VAPOUR OVER NIGERIA CORS NETWORK

71 Student Researchers

ABSTRACT

Water vapour is a very dynamic component of the atmosphere. It greatly influences the atmospheric stabilization mechanism. Hence, it is very difficult to measure or model using classical meteorological systems or models. Tropical atmosphere holds the largest amount of water vapour, thus its characteristics of high climate uncertainty. Interestingly, geodesists have devised methods for estimating the extent to which signals propagated from GNSS satellites to ground‐based GNS...
