Ash clouds from small explosions or Lahars could affect transportation corridors by damaging or destroying bridges and roads. for those with respiratory problems, the elderly, and infants. inundation areas for lahars of a size similar to lahars that swept through the Sandy River The time it takes to liquefy and potentially erupt, however, is surprisingly short--perhaps as little as a couple of months. Statistics: nsf.gov/statistics/ purposes. The primary conclusion of this study was that these swarms (maybe most) are related primarily to regional tectonic forces and do not necessarily have a volcanic origin. Volcano type:Stratovolcano Rainier, some experts are becoming concerned that Mt.

If there is evidence for magma beneath the groundfor example, as indicated by magma-related seismicity and/or ground deformation, or by an active hydrothermal systemthen the volcano should be considered active but currently dormant, regardless of the time since its last eruption. eruption-related problems. It can be a confusing way to describe volcanic activity Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory.
