This article explores the diverse types of volcanoes, including shield volcanoes, cinder cones, stratovolcanoes, and calderas. It provides notable examples such as the Hawaiian volcanoes, Mount St. Helens, and the Deccan Plateau's flood basalts. Additionally, it addresses the increase in magma viscosity, which can lead to more violent eruptions and decrease their frequency. Understanding these characteristics helps in assessing the impact of volcanic activity on the environment and human safety.
