A volcano is generally a conical shaped hill or mountain built by accumulations of lava flows, tephra and volcanic ash. Vulcanism also occurs in the areas that are not associated with plate boundaries in the interior of the plates. These are commonly known as hot spots. They appear to have resulted from plumes of hot… Read More »

Places where most of the volcanic activity takes place

  This article deals with the places where most of the volcanic activity takes place. The distribution pattern of volcanoes is zonal in character. The volcanoes are closely related to the weaker sections of the Earth’s crust and these are closely associated with seismic events such as earthquakes. Based on plate tectonics, there is a… Read More »

Can Earthquakes be predicted?

They lead to shaking of the earth’s surface and are caused due to the tectonic movement of the various plates below the earth’s crust. The places affected by them are divided into seismic zones with the places most severely… Read More »
