Correlation of acoustic emissions with patterns of movement in an extremely slow moving landslide at Peace River, Alberta, Canada
The Peace River region, Alberta, Canada, has experienced extensive landslide activity since deglaciation. Shear zones within weak lacustrine silt and clay layers typically experience continuous creep, damaging highway and utilities infrastructure. However, occasionally, movement accelerates and pote...
