Swiss authorities on Thursday were monitoring for possible flood risk in a southern valley, following a massive glacier collapse that created a huge pile of debris after destroying a small village.<\/p>\n
On Wednesday, the Birch glacier in Switzerland\u2019s southern Valais (Wallis) region collapsed, sending tons of rock, ice and scree hurtling down the mountain slope and into the valley below.<\/p>\n
The barrage largely destroyed the hamlet of Blatten, which had been home to 300 people and was evacuated last week due to the impending danger.<\/p>\n
One person, a man aged 64, believed to be in the affected zone at the time, remained missing. A police spokesman said the difficult conditions had forced the search for him to be called off on Thursday afternoon.<\/p>\n
Authorities declared a local state of emergency on Thursday as they monitor the situation after the huge pile of glacier debris, stretching some two kilometres, blocked the river Lonza.<\/p>\n
\u201cThere is a serious risk of an ice jam that could flood the valley below,\u201d Antoine Jacquod, a military security official, told the Keystone-ATS news agency. \u201cWe\u2019re going to try to assess its dimensions today,\u201d added Jacquod.<\/p>\n
Authorities said an assessment would be made at 6pm (9pm PKT) from the nearby village of Ferden as to whether an approach to the zone could be attempted.<\/p>\n
As a precaution, 16 people were evacuated late on Wednesday from the villages of Wiler and Kippel located downstream from the disaster area in the Loetschental valley, known for scenic views stretching some 30km and home to around 1,500 people living in traditional villages.<\/p>\n

\n\u2018Not very stable\u2019
\n\u201cIt\u2019s like a mountain, and of course, it creates a small lake that gets bigger and bigger,\u201d explained Raphael Mayoraz, the cantonal official in charge of natural hazard management, on Wednesday evening.<\/p>\n
An artificial dam was preemptively emptied to receive the water pushed back by the wall of ice, earth and rubble. Were that water to overflow from the dam, authorities would need to consider evacuating the valley.<\/p>\n
The level is rising 80 centimetres (31 inches) an hour, according to Swiss daily Le Temps.<\/p>\n
The huge amount of debris makes the peaks overlooking the valley appear smaller, while a gaping hole can be seen on the side of the mountain from where the land slid down into the valley.<\/p>\n
The Valais cantonal government has meanwhile asked the army, which set up a base camp in Turtmann on Wednesday and is readying helicopters for making an approach to the affected zone, to provide clearing equipment and pumps to secure the riverbed.<\/p>\n
\u201cThe deposit \u2026 is not very stable, and debris flow is possible within the deposit itself [which] makes any intervention in the disaster area impossible for the time being,\u201d cantonal authorities stated, adding there was risk on both sides of the valley.<\/p>\n
They also warned of a risk of torrential lava within the debris deposit itself, preventing, for the time being, any intervention in the disaster area.<\/p>\n","protected":false},"excerpt":{"rendered":"
