A large-scale evacuation of part of the city began in Tyrnyauz in the Kabardino-Balkarian Republic after a mudslide
A mass evacuation began in Tyrnyauz due to a second mudslide

In the city of Tyrnyauz (Kabardino-Balkaria), the evacuation of a significant portion of residents began after another mudslide. Earlier, residents of houses located near the mudslide channel were forced to leave their homes, according to the Elbrus District Administration.

The municipality urged residents of the Gerhozhan microdistrict to urgently leave their apartments and head to the temporary accommodation centre set up in Lyceum No. 1. Residents were advised to take their documents, necessary medicines and water with them, if possible.

Earlier, car traffic in the city was completely suspended, and a temporary accommodation centre was set up near the mudflow channel for the safety of citizens.

The regional Ministry of Emergency Situations appealed to residents of Kabardino-Balkaria and tourists to refrain from travelling to the Elbrus district.

The mudslide occurred at around 16:30 Moscow time, the second in the last ten days. A few days ago, damaged communications were restored in Tyrnyauz, water supply was resumed, and a new bypass road was opened. Traffic is currently temporarily suspended.

On 21 July, a mudslide in the Gerhozhan-Suu River area destroyed a bridge on the federal highway, after which a state of emergency was declared in the municipality.

For the holidays I took the train going through the "Macif central" mountain in France. It's large but not height mountains. The train was slowed down since 2 months due to consolidation work. I had the opportunity to talk with someone in the train who was supervising the construction site and who told me it was the rain which was creating all the problems with the rocks that threaten to collapse. So yeah, another indicator of the level of rainfall going on I think.

Without denying the fact that these landslides seem to be occurring more and more frequently, especially in the mountains, I lived in this same village for several years, and these landslides occur from time to time. Note that this one occurred at Cirque du Fer-à-Cheval; the name means 'horseshoe-shaped' as its cliffs form a semicircle; its impressive height (2,000 meters) gives rise to a multitude of waterfalls (more than 30), the number of which varies depending on the season.

The Cirque du Fer-à-Cheval is a place with no dwellings, per se; the heart of the village is about 10 kilometers away, although there are a few hamlets on the road between the two. But, when I lived there, these rockfalls (sometimes very little, sometimes a bit less) occured all around the village which is completely surrounded by mountains.

These mounatains are made of limestone rocks, which are very cracked. According to Wikipédia (in French):
The high rainfall in the area accentuates erosion and has caused numerous landslides throughout history.

Yes, high rainfall, added to the snowmelt which increases the size of the many waterfalls and the flow of water, which further contributes to rock erosion; we can therefore expect these rockfalls to increase there, as elsewhere in a near future.

World's second-heaviest 24-hour rainfall recorded in Hue as floods devastate central Vietnam​

By Gia Chinh October 29, 2025 | 12:01 am PT

Rainfall at Bach Ma peak in Hue has reached a staggering 1,739 millimeters in 24 hours, the highest ever recorded in Vietnam and the second-largest daily total in the world, behind only a 1966 record in the Indian Ocean.
Bach Ma peak recorded the historic rainfall from 7 p.m. on Oct. 26 to 7 p.m. on Oct. 27. According to data from the World Meteorological Organization, this 24-hour rainfall was surpassed only by 1,825 mm measured at a French weather station in the Indian Ocean in January 1966.

According to Vietnam's Department of Meteorology and Hydrology, the extreme weather that lashed central Vietnam from Oct. 22 to 28 was triggered by a rare convergence of natural factors: a strengthening cold front, remnants of Storm Fengshen, a tropical convergence zone shifting northward, and intense easterly winds clashing with mountainous terrain.

Rainfall across the region has been exceptional. From Oct. 22 to early Oct. 29, totals reached 450–900 mm in Hue, 300–600 mm in Da Nang and 200–450 mm across Ha Tinh, Quang Tri and Quang Ngai.

The heaviest downpours fell between Oct. 25 and 27, when Bach Ma alone recorded 3,393 mm of rain, followed by 1,457 mm in Tra Thanh (Quang Ngai) and 1,199 mm in Phuoc Thanh (Da Nang).

The relentless rain pushed river levels to dangerous highs. The Bo River at Phu Oc surpassed its 2020 historic flood peak, while the Huong River in Hue rose close to its 1999 level. Dozens of communes in Hue and Da Nang have been submerged under 1–2 meters of floodwater, with some areas reaching 4 meters. At least 10 people have died and five are missing.

Deputy Minister of Agriculture and the Environment Nguyen Hoang Hiep praised Hue authorities and residents for their proactive response and transparent communication, which helped limit casualties despite record rainfall.

Deputy Prime Minister Tran Hong Ha described the floods as "historic," commending reservoir coordination that reduced flood peaks by 0.2–0.3 meters compared to the worst-case scenario.

The National Center for Hydro-Meteorological Forecasting had earlier predicted two phases of heavy rain: first from Oct. 22–24 due to storm remnants and cold air, then from Oct. 25–27 under continued cold air and easterly winds.

In both Hue and Da Nang, total rainfall exceeded 900 mm from Oct. 22 to 27, marking one of the most extreme weather events in Vietnam’s history.
