He nonetheless has the identical view.

Preliminary work will start on creating the 2 hamlets this 12 months.

There might want to protecting constructions constructed, however this type of infrastructure is dear.
A pure hazard skilled on the College of Bern, Andreas Zischg, stated it will be attainable to rebuild in one of many many purple zones within the Lötchental utilizing new infrastructure and obstacles to dam landslides.
“We will both construct avalanche safety constructions or erect giant protecting partitions to cut back the hazard to a medium or residual stage. We will then rebuild on this zone,” he informed Swiss public radio, RTS.
