The study also developed a Geographical Information System (GIS) database and mapped sixteen (16) volcanic cones outcrop in the Jos Plateau and twenty-six (26) of such in the Biu Plateau, Nigeria. The study affirms that volcanic cones of Jos Plateau are composed essentially of volcanic ash, lappilli, bombs, tuff agglomerates, basalts and scoria. Most of them occur as single cinder cones but rarely as clusters of two or more.The study also affirms that Biu Plateau are constituted by a large volume of volcanic ash and pyroclastic material suggesting that there was a tremendous spewing of ash and…mehr

The study also developed a Geographical Information System (GIS) database and mapped sixteen (16) volcanic cones outcrop in the Jos Plateau and twenty-six (26) of such in the Biu Plateau, Nigeria. The study affirms that volcanic cones of Jos Plateau are composed essentially of volcanic ash, lappilli, bombs, tuff agglomerates, basalts and scoria. Most of them occur as single cinder cones but rarely as clusters of two or more.The study also affirms that Biu Plateau are constituted by a large volume of volcanic ash and pyroclastic material suggesting that there was a tremendous spewing of ash and gases into the atmosphere prior to the violent eruptions and in-between the eruptions. GIS analytical techniques like overlying and buffering showed clearly that the population of people living around these volcanoes totals about 1.5 million people.Hence, public awareness about volcanic hazard potentials and encouragement of increased public participation, as well as government and professional intervention in proper management and monitoring of these volcanoes should be encouraged.
