Swiss communities on alert after massive landslide – DW – 05/30/2025
Residents in the Lötschental valley have been asked to prepare for evacuation. It comes after Wednesday's glacier collapse dumped millions of cubic meters of ice, rock and mud.
A number of Alpine communities in Switzerland's Lötschental valley have been asked to be ready to evacuate their homes following a massive landslide on Wednesday.
Rivers in the area have become swollen and have dammed up behind the rubble, rock and ice that thundered down into the valley after the Birch Glacier began to collapse in the southwestern canton of Valais.
"We ask residents to make personal preparations so that they can leave their homes as quickly as possible," the municipalities of Steg-Hohtenn and Gampel-Bratsch in the Lötschental valley posted on their website late Thursday.

Man still missing after Wednesday's collapse
Wednesday's collapse saw millions of cubic meters of ice, mud and rock engulf the village of Blatten and authorities have yet to locate a 64-year-old man who has not been seen since the collapse.
Blatten's 300 residents were evacuated at short notice last week following an assessment by geologists that found that a landslide was imminent.

Local authorities suspended the search for the missing man on Thursday afternoon, as conditions became too dangerous with warnings of further rockfalls.
Rising water levels a concern
The debris has blocked the course of the River Lonza and has caused a lake to form which in turn has heightened fears the mass could dislodge and impact communities further downstream.
Stephane Ganzer, head of the security division for the Valais canton, told reporters that water levels have been rising by 80 centimeters (31.5 inches) an hour as a result of the blockage.

Nigeria: Death toll from major floods passes 150 – DW – 05/31/2025
Torrential rains in central Nigeria on Wednesday triggered flooding and widespread damage. Rescuers say the death toll has surpassed 150 people. The death toll from widespread floods in central Nigeria rose to more than 150 people on Saturday, local emergency services reported. After torrential rains earlier in the week, flood waters have swept away more than 50 homes in the market town of Mokwa in the central Niger state. More than 3,000 people have been displaced.

"I extend my heartfelt condolences to the affected families and the good people of Niger State at this difficult time," Nigerian President Bola Tinubu said in a statement on X. "Search-and-rescue operations are ongoing, and all relevant federal agencies have been mobilised to support the state government's efforts," he added. "Relief materials and temporary shelter assistance are being deployed without delay." Ibrahim Audu Husseini, spokesperson for the Niger State emergency agency told AFP on Friday that he "expected the toll to rise considerably because there are different rescuers at different locations." Why is flooding so dangerous in Nigeria? Mokwa is a key local hub for traders from the south of the country and farmers from the north. It is located around 220 kilometers (140 miles) west of the capital Abuja. The flooding was triggered by several hours of heavy rain, with the collapse of a nearby damn exacerbating the situation. Nigeria's Meteorological Agency warned of possible flash floods in 15 of Nigeria's 36 states, including Niger State, between Wednesday and Friday. Nigeria's rainy season has only just started and normally lasts around six months. The annual occurrence regularly kills hundreds of people. A lack of drainage, the construction of homes on waterways and the dumping of waste in drains and water channels all make the flooding worse.

Swiss glacier collapse: Situation stabilizes overnight – DW – 05/31/2025
Water that had accumulated behind the collapsed glacier has began to flow downstream, alleviating some fears. Forecast rain means that residents will likely have to remain alert. with dpa along with Austrian and Swiss media Following the dramatic rock fall and glacier collapse on Wednesday in the Swiss Lötschental valley, officials said on Saturday that the situation had eased. One fear had been that the Lonza River, which had been backed up behind the ice, rock and debris, could result in a flood wave. However, officials said the river had found new paths down the valley in the southern Swiss canton of Valais. Construction machinery has been deployed to control the run-off of accumulated water. The municipalities of Gampel and Steg informed residents of the work, saying: "The aim is to ensure the smooth flow of debris and alluvial debris through the bed of the Lonza stream within the villages." Authorities expressed relief that the Lonza River has begun to flow down the valley, reducing the risk of a flood swell Image: Jean-Christophe Bott/KEYSTONE/picture alliance What did authorities say about the Swiss glacier on Saturday? Stephane Ganzer, from the Valais state council, said that there had been no major problems overnight. The situation on Saturday was "currently satisfactory" and the night had been "quite quiet," Austrian public broadcaster ORF reported. The council decided on Friday evening to open a nearby dam, warning residents downstream to make way for the water. Residents were already on alert and ready to evacuate in the case of a dangerous swell of water behind the debris cone. The heat has sped up the melting of the glacier ice and rain has been forecast for the next days. Both could lead to a buildup of accumulated water and increase the risk of further landslides.

Millions of cubic meters of ice and rock were sent crashing through the Lötschental valley and burying the village of Blatten, which had already been evacuated. Water from the Lonza was then blocked behind the almost 2-kilometre-long debris cone. Blatten's municipal president Matthias Bellwald said the village would be rebuilt. "Blatten is under a debris cone. Together we will do what is humanly possible to rebuild the village for the village to have a future. Together we are strong," Swiss newspaper the Neue Zürchner Zeitung quoted him as saying at a press conference.
