Pseudocraters at Myvatn

Pseudocrater at Myvatn lake, Iceland.
A pseudocrater is a volcanic landform which resembles a true volcanic crater, but differs in that it is not an actual vent from which lava has erupted.
Pseudocraters are formed by steam explosions as flowing hot lava crosses over a wet surface, such as a swamp, a lake, or a pond. The explosive gases break through the lava surface in a manner similar to a phreatic eruption, and the tephra builds up crater-like forms which can appear very similar to real volcanic craters. (Wikipedia)
Pseudokraater on pinnavorm, mis meenutab vulkaanilist kraatrit. Psudokraater moodustub aga mitte laava, vaid kuuma auru purske tagajärjel, kui kuum laava puutub kokku järve või soo veega.
