In the first two days of the eruption, ice cauldrons were formed over the volcanic vents. [4] Radar images reveal the development of these cauldrons in a 200 m thick ice cover within the summit caldera. They can also be used to document the subglacial and supraglacial passage of meltwater away from the eruption site. Research shows the eruption ...
These ice cauldrons "are created by melting at subglacial geothermal areas". [5] The meltwater accumulates in lakes "under the cauldrons until it drains every 2–3 years in a jökulhlaup" of normally up to 2,000 m 3 /s (71,000 cu ft/s). [4] An unusually big outburst flood (jökulhlaup) was recorded in 2015.
Mud pots: Boiling mud pools of various colors, including the "Black Cauldron" with highly acidic water. [2] Ice caves: Formed by the interaction of volcanic heat and glaciers on the volcano's slopes. [2] Vulkannaya River: Originates from melting glaciers and snow fields, carrying dissolved minerals and acids. [2]
Snow ratios can far exceed the 10:1 rule of thumb: In the 24 hours ending the morning of Jan. 21, 2024, parts of the Alleghenies saw 2 to 4 inches of snow from just 0.05 to 0.08 inches of liquid ...
Ice-melt crystals on a paved sidewalk for snow removal. (Getty Images) This surface layer of semi-liquid ice comes only a few molecules thick at the melting point, and has the ability to vibrate ...
Glacial pothole in Bloomington on the St. Croix River at Interstate State Park, Wisconsin, U.S.. A giant's kettle, also known as either a giant's cauldron, moulin pothole, or glacial pothole, is a typically large and cylindrical pothole drilled in solid rock underlying a glacier either by water descending down a deep moulin or by gravel rotating in the bed of subglacial meltwater stream.

Days after a winter storm dropped ice and record-breaking snow, cleanup efforts were underway Thursday in several major Southern cities such as New Orleans, where crews were removing snow the same ...
Cauldron – a large metal pot for cooking or boiling over an open fire, with a large mouth and frequently with an arc-shaped hanger. Chafing dish and stand, circa 1895, [16] Victoria and Albert Museum, London. Ding – prehistoric and ancient Chinese cauldrons, standing upon legs with
