SUMMARY:Geology & Environmental Science Colloquium: Dr. Steve McNutt | Uni
 versity of South Florida
LOCATION:Thaw Hall 104\, 3943 O'Hara Street\, Pittsburgh\, PA 15213
DESCRIPTION:Long Swarms and Short Swarms at Volcanoes: Evidence for Differ
 ent Processes (part 1) and Estimates of Water in the Hunga Tonga plume (p
 art 2)\n\nPresented by Dr. Steve McNutt | Professor\, University of South
  Florida\n\nTalk Abstract:\n\nVolcanoes often show earthquake swarms of d
 ifferent durations. Long swarms (weeks to months) are characterized by a 
 low b-value\, suggesting increased pressure at depth. These are followed 
 by short swarms (hours-days) with higher rates and 30-50 percent VLP even
 ts\, suggesting pulses of magma injection. A case study of Hunga Tonga es
 timates the amount of water in the enormous plume and uses this to determ
 ine energetics of the eruption.\n\nBiography:\n\nSteve McNutt is a volcan
 o seismologist who has spent over two decades working with the Alaska Vol
 cano Observatory\, studying some of the world's most active and unpredict
 able volcanic systems. His research spans an unusually wide range of volc
 anic phenomena\, including the source and propagation of volcanic tremor\
 , low-frequency events\, and explosion earthquakes\; the mechanical behav
 ior of volcanoes (from eruption periodicity to how earth tides\, sea leve
 l changes\, and tectonic stress can trigger eruptions)\; volcano infrasou
 nd and volcanic lightning.\n\nToday\, Dr. McNutt coordinates volcano seis
 mology research in the Department of Geosciences at the University of Sou
 th Florida and has served as Secretary-General of the International Assoc
 iation of Volcanology and Chemistry of the Earth's Interior\, helping sha
