Confidence votes 252. Hydrostatic pressure is the pressure which is exerted on a portion of a column of water as a result of the weight of the fluid above it. Hydrostatic pressure is what is exerted by a liquid when it is at rest.The height of a liquid column of uniform density is directly proportional to the hydrostatic pressure. The hydrostatic properties of a liquid are not constant and the main factors influencing it are the density of the liquid and the local gravity.he height of a liquid column of uniform density is directly proportional to the hydrostatic pressure.

This eruption was the biggest eruption in recorded history. Geography. Tambora is a stratovolcano located on the island of Sumbawa in Indonesia (see map below), forming the Sanggar peninsula of the island. The island is part of a very active volcanic arc, which is part of the Ring of Fire around the Pacific Ocean. Map Courtesy of United States Geological Survey. Public Domain.
A view from the caldera rim of Tambora, taken June 2008. Paul Hessels / Wikimedia Commons. Before the eruption in 1815, Tambora was a volcano that might have been 4,300 meters (~14,100 feet) tall. Thatâs about the same size as Mt. Rainier*. One of the biggest results of the 1815 eruption was the generation of a caldera â a large depression caused by the volcano falling in on itself after emptying its innards during the eruption (see the image at the top).
