After the storm is the fear of landslides

Storm No. 3 has passed, but its echoes are still present in the highland communes of the province with the fear of landslides. When the "water-filled" rocks and soil on the mountainside can collapse at any time...

After the storm, mountainous areas are again worried about landslides.

The rain stops, the worries begin

According to information from the Phu Tho Province Civil Defense, Disaster Prevention and Control and Search and Rescue Command, from July 21 to the morning of July 23, due to the impact of storm No. 3, many areas in the province experienced heavy rain, causing water to seep deep into the ground, increasing the risk of landslides. By 8:30 this morning (July 23), according to records in Duc Nhan commune, 2 inter-hamlet roads had ^1,000m3 of landslides spilling onto the road surface, causing traffic jams.

Two inter-hamlet roads in Duc Nhan commune were damaged by landslides, causing traffic congestion.

In Pa Co commune, the situation is even more worrying. Four households in Hang Kia hamlet had large rocks from the positive slope on Highway DH.65 roll down close to their walls. Mr. Vang A De shared his worries: My house is right under the road, rocks as big as a coffee table rolled down less than 5m from my house. Now every time it rains, I shiver, not knowing when it will roll again. If we evacuate, we are worried about our house, but if we stay, we are afraid of danger to our lives.

According to comrade Tran Van Truyen - Chairman of Pa Co Commune People's Committee: To ensure safety, the Commune People's Committee has mobilized households with houses in areas at risk of landslides to temporarily relocate to relatives' houses to ensure safety. As for the DH.65 route, the commune has mobilized forces to clear soil and rocks to temporarily open traffic. However, if the rain continues, the possibility of further landslides is very high.

According to forecasts, there will continue to be rain in the province in the coming time, so the risk of landslides is still unpredictable.

Not only on DH.65 route but also on the inter-commune road connecting Hang Kia hamlet (Pa Co) with Ta De hamlet, Van Ho commune ( Son La ) there was a landslide at Km 0+900, causing complete blockage. In Quy Duc commune, heavy rain and storms caused a household's house wall to collapse due to soil from the positive slope collapsing. In addition, another household had cracks in the wall and floor due to subsidence from the negative slope.

In Mai Ha commune, the authorities urgently evacuated 13 households in areas at high risk of landslides to safety. Among them were 12 households in Thanh Mai hamlet and 1 household in Lau hamlet. In Minh Dai commune, 4 households had their houses flooded by rocks and soil...

On July 23, according to reports from communes and wards, after the recent storm, dozens of large and small landslides appeared in the whole province, hundreds of cubic meters of rock and soil slid down onto roads and residential areas. Local authorities in the whole province evacuated 719 households in areas at risk of landslides and flash floods to safe places.

Authorities support families living in areas at high risk of landslides in Thanh Mai hamlet, Mai Ha commune to safe shelters.

Serious landslides also occurred in many lakes, spillways, and irrigation works such as: Hong Kien spillway in Minh Dai commune, about 20m2 of the embankment slope was eroded; Na Ai irrigation lake in Tan Lac commune, the dam foot was eroded ^3m deep, 10m long, the volume of soil slid about ^100m3 ...

Warning of widespread landslide risk

Comrade Nguyen Hung Son - Chief of Office of the Civil Defense, PCTT and TKCN Command of Phu Tho province said: After storm No. 3 with heavy rain, some areas have reached saturation (over 85%). This reduces the binding force of soil and rock, making the risk of landslides extremely high. Especially in mountainous areas and residential areas at the foot of the hills.

After storm number 3, many places in the province have reached a state of saturation.

According to the latest announcement of the Phu Tho Province Hydrometeorological Station at 3:30 p.m. on July 23, it is forecasted that in the next 24 to 48 hours, due to the influence of the active tropical convergence zone. From tonight (July 23) to the afternoon of July 25, there will continue to be showers and thunderstorms in the province. Locally there will be heavy rain with rainfall ranging from 20mm to 70mm. Some places will have rainfall of over 100mm. Locally heavy rain is likely to cause flooding in low-lying areas, flash floods on small rivers and streams.

In particular, it will increase the risk of landslides and land subsidence. In particular, localities with high risk of landslides include: Quy Duc, Mai Chau, Pa Co, Tan Lac, Cao Son, Da Bac, Muong Bi, Yen Son, Ngoc Son, Tan Mai, Tan Pheo, Van Son, Yen Son, Duc Nhan, Huong Can, Kha Cuu, Lai Dong, Long Coc, Thuong Long, Xuan Dai...

causing floods on small streams and landslides in many places in Tan Son commune

Faced with this dangerous weather pattern, the Provincial Steering Committee for Civil Defense, PCTT and TKCN has directed localities to strengthen weather monitoring, organize forces to inspect locations and places at high risk of landslides; promptly post warning signs, assign guards on roads and vulnerable residential areas; implement the "4 on-site" motto to be ready to respond to all natural disaster situations. Along with that, continue to propagate and instruct people to recognize signs before landslides occur such as: cracked soil, unusual water seepage, scattered rolling rocks... to proactively evacuate in time.

Authorities clean up trees broken by landslides.

Storm No. 3 has dissipated, but the dangers it left behind still lurk on every roof and every road in the highland communes. When natural disasters are no longer just storms but long-term consequences after the rain, proactive response, evacuation of residents and reinforcement of roads and slopes need to be implemented more urgently and decisively than ever.

The lessons of response, adaptation and vigilance never get old. Especially in the highland communes of the province. Where landslides can start right after a rainstorm...
