Photo @Keith Ladzinski / Braided streams of sediment flow, known as Lahar, moving over the glacial wetlands of inland Iceland. #Lahar is the result of a volcanic eruption, or indirectly by the collapse of loose material on the flanks of a volcano. A variety of phenomena may trigger a lahar, including melting of glacial ice due to volcanic activity, intense rainfall on loose pyroclastic material, or the outburst of a lake that was previously dammed by pyroclastic or glacial sediments. information sited from Wikipedia. @クリス・バーカード @prana @3stringsproductions
