SHAKE AND BLOW
Yellowstone Geyser Eruptions Mostly Influenced By Internal Processes
by Staff Writers
New York NY (SPX) May 12, 2014


Dr. Shaul Hurwitz took advantage of a decade of eruption - spanning from 2001 to 2011 - for two of Yellowstone's most predictable geysers, the cone geyser Old Faithful and the pool geyser, Daisy.

The intervals between geyser eruptions depend on a delicate balance of underground factors, such as heat and water supply, and interactions with surrounding geysers. Some geysers are highly predictable, with intervals between eruptions (IBEs) varying only slightly.

The predictability of these geysers offer earth scientists a unique opportunity to investigate what may influence their eruptive activity, and to apply that information to rare and unpredictable types of eruptions, such as those from volcanoes.

Dr. Shaul Hurwitz took advantage of a decade of eruption - spanning from 2001 to 2011 - for two of Yellowstone's most predictable geysers, the cone geyser Old Faithful and the pool geyser, Daisy.

Dr. Hurwitz's team focused their statistical analysis on possible correlations between the geysers' IBEs and external forces such as weather, earth tides and earthquakes. The authors found no link between weather and Old Faithful's IBEs, but they did find that Daisy's IBEs correlated with cold temperatures and high winds. In addition, Daisy's IBEs were significantly shortened following the 7.9 magnitude earthquake that hit Alaska in 2002.

The authors note that atmospheric processes exert a relatively small but statistically significant influence on pool geysers' IBEs by modulating heat transfer rates from the pool to the atmosphere. Overall, internal processes and interactions with surrounding geysers dominate IBEs' variability, especially in cone geysers.

New insight may help predict volcanic eruption behavior
Liverpool, UK (SPX) May 06, 2014
A new discovery in the study of how lava dome volcanoes erupt may help in the development of methods to predict how a volcanic eruption will behave, say scientists at the University of Liverpool. Volcanologists at the University have discovered that a process called frictional melting plays a role in determining how a volcano will erupt, by dictating how fast magma can ascend to the surfac ... read more
