Geothermal Energy Release at the Solfatara of Pozzuoli (Phlegraean Fields): Phreatic and Phreatomagmatic Explosion Risk Implications
The H20, CO2 and H2S outputs at the Solfatara of Pozzuoli have been measured and a map of the exhaling areas has also been made. The energy released at the surface by the fluids has been estimated to be 1019 ergs/day. The presence of aquifers at Phlegraean Fields increases the phreatic and phreatomagmatic explosion risk. Our results suggest that even if an uprising magma may interact with water...
متن کاملLahar Infrasound Associated with Volcán Villarrica's 3 March 2015 Eruption
The paroxysmal 2015 eruption of Volcán Villarrica (Chile) produced a 2.5 h long lahar, which descended more than 20 km within the Rio Correntoso/Turbio drainage and destroyed two small bridges. A three-element infrasound array 10 km from the summit, and 4 km from the lahar’s closest approach, was used to study the flow’s progression. Array processing using cross-correlation lag times and sembla...
متن کاملPreparatory and precursory processes leading up to the 2014 phreatic eruption of Mount Ontake, Japan
We analyzed seismicity linked to the 2014 phreatic eruption of Mount Ontake, Japan, on 27 September 2014. We first relocated shallow volcano tectonic (VT) earthquakes and long-period (LP) events from August to September 2014. By applying a matched-filter technique to continuous waveforms using these relocated earthquakes, we detected numerous additional micro-earthquakes beneath the craters. Th...
متن کاملTo record or not to record?
A question that comes up over and over again in my practice — from clients and opposing attorneys alike — is whether a lease document should be recorded in the relevant county's real property records office, usually the county clerk's office. Specifically, people ask, "What difference dews it make whether the lease document is recorded?" Well, to answer this question, we must ask a couple more ...
متن کاملUpdating the Historical Sunspot Record
We review the evidence for the argument that Rudolf Wolf’s calibration of the Sunspot Number is likely to be correct and that Max Waldmeier introduced an upwards jump in the sunspot number in 1945. The combined effect of these adjustments suggests that there has been no secular change in the sunspot number since coming out of the Maunder Minimum ∼1715. 1 The Sunspot Record(s!) The Sunspot Recor...
