Role of borehole observations in comprehending natural hazards

Session ID#: 80179

Session Description:
Borehole observations are gaining importance globally for a variety of usages including comprehending natural hazards with observations made in a shallow (10’s to 100’s of m) to deep (from depths of 1 to ~ 10 km) boreholes. These efforts include deploying a variety of downhole sensors such as seismometers, stress and strain measuring devices, heat flow measurements, collection of fluids for elucidating physical processes, collection of rock samples for paleo-earthquakes/tsunamis/microbial-studies etc. Operation of borehole seismic networks has improved location capabilities of earthquakes by an order of magnitude. Very useful results have been obtained by running borehole networks in many active fault zones. These include but are not limited to recent research efforts such as the SAFOD, USA; Koyna, India; Nankai/Sendai, Japan; GONAF, Turkey; South Africa gold mines (DSEIS). With this session we intent to review the current state of the art in this emerging field and to define future challenges.
