Heavy rainfall across multiple regions in Yunnan has triggered a series of geological hazards, prompting swift responses from local authorities.

In recent days, several areas in Yunnan have experienced intense short-duration rainfall, including Yuxi, Wenshan Zhuang and Miao Autonomous Prefecture, Qujing, Zhaotong, and Baoshan. These regions mobilized quickly in response to the flood conditions, strengthening risk inspections for geological hazards at the source. Strictly adhering to the principles of "three emergency avoidance measures" and "four unified standards," they effectively managed personnel evacuation and control. This proactive approach successfully averted 10 geological disasters, safeguarding the lives of 275 people across 91 households. Here are the detailed accounts:

First: Successful Landslide Evacuation in Guojing Community, Daying Street, Hongta District, Yuxi on August 6

On July 27, security guard Liang Houxiang at the Yuxi Yuefeng Steel Pipe Industry and Trade Co., Ltd. dormitory building discovered a cracked and deformed road in front of an old dormitory, accompanied by partial collapse of the slope below. He immediately reported the situation to the company. Following the report, officials from the Daying Street Office, the Hongta District Natural Resources Bureau, the Yuxi Natural Resources and Planning Bureau, and the technical guidance station quickly arrived for an on-site investigation. After confirming a high risk of landslide in the area, they promptly organized the evacuation of residents to safety.

At around 10:00 AM on August 6, the cracks at the rear edge of the landslide zone continued to expand, leading to significant sliding and deformation. This caused the living area's floor to crack and damage, a wall to collapse, and some roads to be blocked, with direct economic losses of approximately 450,000 yuan. Thanks to the heightened awareness of grassroots residents in identifying and reporting hazards, the timely joint departmental inspection and disposal, and the decisive evacuation, 13 households (34 people) were effectively protected from potential disaster-related casualties.

Second: Successful Landslide Evacuation in Huixiangdi Village, Longgeli Village Committee, Luzhi Town, Yimen County, Yuxi on August 10

At 3:37 PM on August 10, the Yuxi Meteorological Observatory issued a Level IV thunderstorm warning, forecasting thunderstorm activity with localized short-duration heavy rainfall over the next 12 hours. At 4:00 PM, geological hazard monitors Yuan Shaofa and Yuan Shaoqing from the Huixiangdi villager group discovered small-scale collapses on the slope behind the village during a routine inspection. They immediately reported the information and simultaneously organized the evacuation of 6 affected households (16 people) to safe areas.

At 4:10 PM on August 10, the surface soil on the slope began to release more water, resulting in a large-scale slide. Mud and debris rushed into several residents' homes and courtyards, damaging some walls and pig pens, with direct economic losses exceeding 30,000 yuan. The timely identification of the hazard and effective evacuation measures successfully ensured the safety of the threatened residents' lives.

Between 4:40 PM and 7:00 PM on August 10, officials from Luzhi Town and Longgeli Village Committee, along with the technical guidance station, returned to the site for post-disaster verification. After determining a risk of secondary sliding, they further strengthened control over the danger zone and management of the evacuated population.
