A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. The process that forms volcanoes is called volcanism. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth ...
Ring of Fire. The Ring of Fire (also known as the Pacific Ring of Fire, the Rim of Fire, the Girdle of Fire or the Circum-Pacific belt) [note 1] is a tectonic belt of volcanoes and earthquakes. It is about 40,000 km (25,000 mi) long [1] and up to about 500 km (310 mi) wide, [2] and surrounds most of the Pacific Ocean.
The main feature of the Ngorongoro Conservation Authority is the Ngorongoro Crater, the world's largest inactive, intact and unfilled volcanic caldera. [21] The crater, which formed when a large volcano erupted and collapsed on itself two to three million years ago, is 610 metres (2,000 feet) deep and its floor covers 260 square kilometres (100 ...

The dashed trajectories are the result of lava pieces with a bright hot side and a cool dark side rotating in mid-air. Volcanology (also spelled vulcanology) is the study of volcanoes, lava, magma and related geological, geophysical and geochemical phenomena (volcanism). The term volcanology is derived from the Latin word vulcan.
Mount Batulao. Mount Batulao is an inactive stratovolcano in the Calabarzon region of the Philippines, located in northwest Batangas province along its border with Cavite. [1][3] It is a dissected andesitic stratovolcano at the northwestern rim of the Taal Caldera which began to form in the late Pliocene period, about 3.4 million years ago. [4]
Mount Kitanglad is an inactive volcano [9] located in the Kitanglad Mountain Range in Bukidnon province on Mindanao island. It is the fourth highest mountain in the Philippines and has an approximate height of 2,899 metres (9,511 ft). [Note 1] It is located between Malaybalay City and the municipalities of Lantapan, Impasugong, Sumilao, and Libona.
