The point or location where a fire begins, referring to an outbreak of flames or the origin of a blaze in a fire incident.
An opening or apparatus designed for igniting a fire, such as the nozzle where flames are emitted, commonly used in various ignition systems.
The vent or opening of a volcano through which lava and gases are expelled during an eruption, often forming distinctive geological features.
The mouth or aperture used to introduce combustible material into a furnace or boiler for burning purposes.
A specific geological formation in which water collects in a depression created by volcanic activity, often leading to the formation of a crater lake.
A body of water that forms within a volcanic crater, created by the accumulation of rainwater or melting snow.
A lake situated at the bottom of a volcanic caldera, often surrounded by steep walls formed from volcanic rock.
A water-filled depression resulting from the collapse of a volcanic vent, typically characterized by its unique geological features and ecosystem.
A geological feature formed at the summit of a volcano, where volcanic materials such as lava and ash escape during an eruption.
The specific opening or vent through which volcanic eruptions occur, characterized by a circular or bowl-like depression.
A depression at the top of a volcano that serves as the outlet for magma and gases during volcanic activity, often leading to explosive or effusive eruptions.
The location where a fire begins or ignites, often referring to the initial source of flames in a fire incident.
A part designed to facilitate ignition, such as the opening or mechanism used to create or manage a flame.
The opening at the summit of a volcano where magma and gases escape, often associated with volcanic eruptions.
A structure that surrounds the fire source in a furnace or boiler, directing heat and ensuring efficient combustion.
The nozzle at the end of a gas welding tool, from which the flame is emitted for welding or cutting purposes.
The point where a fire originates or begins to burn, commonly associated with the starting location of a fire incident.
An opening or mechanism used to ignite a fire, often referencing the part of a tool or device that produces a flame.
The vent or outlet of a volcano, where magma is expelled during an eruption, characterized by a bowl-shaped formation.
A structure that encircles the vent of a volcano, typically exhibiting steep inner slopes and more gradual outer inclines.
