Volcanoes are not bound to one eruptive style, and frequently display many different types, both passive and explosive, even in the span of a single eruptive cycle. [3] Volcanoes do not always erupt vertically from a single crater near their peak, either. Some volcanoes exhibit lateral and fissure eruptions.
A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, ...

A mud volcano or mud dome is a landform created by the eruption of mud or slurries, water and gases. [1] [2] [3] Several geological processes may cause the formation of mud volcanoes. Mud volcanoes are not true igneous volcanoes as they do not produce lava and are not necessarily driven by magmatic activity.

Volcanoes are usually mountains (sometimes islands, lakes, plateaus, calderas, seamounts or lava domes) that are formed when magma (liquid rock) wells up from inside the Earth. There are also analogous formations away from the Earth. Many volcanoes are categorized both as volcanoes and other landforms, such as mountains (if qualified).
A polygenetic volcanic field is a group of polygenetic volcanoes, each of which erupts repeatedly, in contrast with monogenetic volcanoes, each of which erupts only once. [1] Polygenetic volcanic fields generally occur where there is a high-level magma chamber.
The three exceptions are Cabalian, which is a strongly fumarolic volcano; [further explanation needed] Leonard Kniaseff, which was active 1,800 years ago (C14), [2] and Isarog, which last erupted around 3500 BCE and 2374 BCE ± 87 based on radiocarbon dating [3] [4] [5] Volcanoes in the country have erupted within the last 600 years, with ...
