W-13 Geophysics Applied to Geohazards and Public Safety

Date: Friday, 23 September
Time: 8:30 a.m.-5 p.m.
Henry B. Gonzalez Convention Center, Room 214 C
Organizers: Rick Miller 
Through the support of the Near Surface Geophysics Section

Description:

Geohazards are found across a wide range of geologic settings, with varying degrees and types of risk to public safety. More and more, exploration geophysicists are being called upon to use the many tools of their trade to either evaluate potential hazards or determine how much more impact a recently developed hazard will have. This area of study and practice includes an enormous range of continuously changing and evolving applications and geophysical tools. The need for subsurface characterization of geo-risk areas will increase and diversify as the world's population expands and humanity settles and develops areas our ancestors avoided due to natural hazards. It seems timely, with the increased publicity natural disasters have received over the last few years, that the instrumental/critical role geophysics plays in many identification and monitoring activities is the topic of a workshop. 

This workshop will revolve around five topical areas: 

  • Subsidence
  • Ocean bottom stability
  • Earthquakes
  • Landslides
  • Glacial/permafrost

With nearly one dozen solicited speakers presenting and leading discussions after each topical area, this workshop should provide ample opportunities to delve into both the technical and social/economic/political aspects of geohazards and how geophysics is improving public safety.
