Geyser geothermal fields are scenic volcanic landforms that often contain tens to hundreds of thermal spot vents erupt boiling water or bubbling mud pools. The potentially hazardous sites due temperatures and changes in vent locations eruption dynamics, which poorly understood. Here we report on the rapid profound can affect such a geyser field ultimately lead dangerous, unanticipated eruption....

In comparing two populations, sometimes a model incorporating a certain probability order is desired. In this setting, Bayesian modeling is attractive since a probability order restriction imposed a priori on the population distributions is retained a posteriori. Extending the work in Gelfand and Kottas (2000) for stochastic order specifications, we formulate modeling for distributions ordered ...

The eruption frequency of geysers can be studied easily on the surface. However, details internal structure including possible water and gas filled chambers feeding eruptions driving mechanisms often remain elusive. We used a multidisciplinary network seismometers, video cameras, pressure sensors one tiltmeter to study eruptive cycle, structure, cycle Strokkur geyser in June 2018. An at always ...
