Some magmas contain enormous amounts of dissolved gas sometimes up to several percent gas by weight. Magma flowing or bubbling beneath a volcano can sometimes interact with groundwater in the area. A maar is formed by one or more underground explosions that occur when hot magma comes into contact with shallow ground water to produce a violent steam explosion. Tanaga Volcano is about 5 miles (8 km) west of Takawangha volcano on Tanaga Island. (Craters formed by explosions at or near the surface of the Earth are simply called explosion craters. They occur in at least three geologic situations: 1) in volcanic areas where hydrothermal activity produces steam and gas pressure that mobilizes mud and forces it to the surface; 2) where tectonic activity forces fluidized sediments to the surface; and, 3) where fluidized sediments pressurized by hydrocarbons are driven to the surface. Because of their high temperature they glow momentarily, producing a streak of light. Fishing, taking anything . [11] The location of one such maar was Elie Ness.[12].

Flank craters can form at lower altitudes than summit craters, near hillside towns. This small particle size allows impurities to be separated from the target material. Soon after, smaller eruptions began piling up lava and volcanic ash on the crater floor, slowly rebuilding the mountain.Volcanoes can also create craters when the magma comes into contact with water. The upper layer ultimately collapses under its own weight, forming a bowl-shaped depression that resembles a crater. Meteoroids can be travelling at speeds of 20 kilometers per second or more.

The debris often lands in a circular pattern around the site of the explosion, creating a crater.Explosions can be natural or artificial. An excellent example of a maar is Zuni Salt Lake in New Mexico, a shallow saline lake that occupies a flat-floored crater about 6,500 feet across and 400 feet deep. Many different types of moraines are distinguished: terminal, ground, lateral, ablation, medial, push, and recessional. Most volcanoes are constructional in that they build landforms. It is a dormant volcano, which still emits jets of steam with sulfurous fumes. Maar lakes, also referred to simply as maars, occur when groundwater or precipitation fills the funnel-shaped and usually round hollow of the maar depression formed by volcanic explosions. A maar is a small, shallow volcanic crater with steep sides that forms in an explosive volcanic eruption that is triggered when rapidly ascending magma contacts groundwater at a shallow depth and a steam explosion occurs. The blast spread tephra over an area of about 2,500 square kilometers. It can serve as a source of magma and gases for volcanic eruptions if it connects to the surface through a pipe or connects to another magma chamber through a dike or a sill.
