In detail
This geyser formed in 1906, after an earthquake. There are several hot springs on Edo Laki Island – and one of them started a furious activity. Approximately two times per minute the water from this spring burst high up in the air. Bursts lasted just a few seconds but the fountain was 25 – 30 m high.
As time went by, geyser became less powerful. In 1926 the height of the geyser was just 1 m and it burst just once per (approximately) 30 minutes. There is a contradicting report from 1963 – 1964, which reports that geyser was 2 m high then.
In 1965 in the site of the geyser was a circular basin with a diameter of 2 m. Water in this basin fluctuated by 5 – 10 cm every 9 – 10 minutes. In 1970 even this surge was not noticeable.
Today here is located very hot spring with the temperature of water 96°C. Water is alkaline, with pH 8.36.

Springs
Powerful natural freshwater springs belong to the most fascinating monuments of nature. Even more exciting is the diversity of unusual springs – mineral springs, hot springs, submarine springs as well as the unusual black smokers. Especially beautiful are such natural rarities as travertine, silica, or salt terraces created by warm and hot springs and, especially, geysers.
Geysers
Hasty hydrogeologists would say: geysers are thermodynamically and hydrodynamically unstable hot springs. “Normal” people would say – geysers are hot springs that at more or less regular intervals shoot up a fountain of boiling water and steam. Sometimes these fountains are even 100 m tall… or even 450 m!
