TAPPEN, B.C. — A landslide that destroyed two houses near Tappen Friday was likely caused by groundwater seepage.
Emergency Operations Director Ryan Nitchie of the Shuswap Emergency Program says preliminary investigation has determined the slide was “a naturally-occurring event.”
“Preliminary geotechnical assessment basically determined that this seemed to be a naturally-occurring event, with a failure of a layer of calcium carbonate, and an organic layer that slipped over bedrock and caused the landslide event.”
“This event is caused primarily through groundwater seepage, but the rain that we had also saturated the ground, and apparently contributed to the problem as well.”
