Wondered why geysers erupt periodically? The riddle has been solved by researchers at the University of California, Berkley. In a new study they reveal that geysers have underground tunnels circled with a lot of side-rooms which causes steam to warm up the water and make it jet out.
All the process is depicted in detail in the February number of the Journal of Volcanology and Geothermal Research.
Volcano experts from Berkeley, overseen by Carolina Munoz-Saez, a UC Berkeley graduate study from Chile and professor of Earth and Planetary Science, Michael Manga discovered that underground loops and curves that block steam prompts a gradual increase in water temperature above it until it is pretty close to the boiling point.The water areas heat up water from the top down, which leads to steam and water being ejected many feet into the air.
Manga expressed the aim of the research as follows:
“One of our goals is to figure out why geysers exist – why don’t you just get a hot spring – and what is it that controls how a geyser erupts, including weather and earthquakes”.
Manga dedicated years to studying the dynamics behind geysers. He observed them in Yellowstone, which hosts 50% of the world’s geysers and Chile. Manga and his understudies likewise constructed their own geyser in a research center from glass with a loop. The lab experiment also ejects water occasionally but not as routinely as a genuine geyser. El Jefe, for instance, located in the Atacama Desert in Chile emits at regular intervals of about 132 seconds.
On our planet there are around 1,000 geysers and every one of them is housed in previously active or active volcanic region. Surface water retreats into the soil and gets warmed up by magma and afterward climbs back to the surface as mud pots, hot springs or geysers.
Manga is examining geysers to find out more about volcanoes and volcanic eruptions,which are to some degree like geysers, yet much harder to re and monitor. The volcanologist collected his data by embedding temperature and pressure sensors 30 feet deep into the giant ‘fountains’. Afterwards he paralleled the information with estimations got from the surface by seismic sensors. Along these lines he projected the chain of events from the underground that pave the way to an eruption. The specialists have collected data comprising a six-day observation of El Jefe. They tracked a cycle of 3,600 emissions, which was then contrasted with ejections occurring at Yellowstone National Park.
After the examination, the specialists discovered distinct stages. In the first phase, water goes back into the geysers after an eruption. In the next one, steam pentrates the area from below. In the last phase, called relaxation, the temperature and pressure continue to drop until recharge state starts once more.
