Tiegan E. Hobbs, PhD, MSCE

A very short (30 minute) recurring discussion group for all things relating to active faults, paleoseismology, seismic risk, seismic hazard, and associated geohazards in Canada. All are welcome!
Meetings are Tuesday from 1:30-2pm Pacific Time (Vancouver) on zoom. Connection info is provided at the bottom of the page. If there is ever a paper you need access to, just send me a message.
