Felssturz blocks Lesachtaler Straße: Access to Obergaill closed!

On April 20, 2025, a heavy rock fall occurred in the municipality of Lesachtal at around 7 p.m. The demolition point is located north of the Gailbrücke and led to the blockade of the access road to the village of Obergaill. This road was laid by the crashed rock masses at several meters, which led to a total lock.

The affected residents of the region have only a provisional forest path access to about 15 farms. The municipal road remains closed on April 22, 2025 until the assessment by the state geologist on April 22, 2025. The preliminary assessment indicates that the evacuation of the rock fall could take several days, whereby the exact duration depends on the geological analysis. So far there are no injuries, but there is still great uncertainty among the inhabitants.

causes and dangers of rock falls

The phenomenon of the rock fall can have many causes. As lgrb-bw.de , frequent causes are weathering, especially along separation areas that lead to individual rocks from the rock bandage. Rocking events that occur up to 10 m³ with total volumes are classified as a rockfall or block blow. With a slope angle of less than 30 °, the rock components usually come to a standstill.

Such rock -talent events were documented in the region around Lesachtal, which are favored by granular and brittle materials. After the rock fall, the effectiveness of forests is crucial: they can dampen crashing rocks and reduce their speed.

prevention measures and danger assessment

The handling of such dangers requires comprehensive planning and prevention measures. As geology.sachsen.de , experts should be instructed in order to assess the risk situation. Specific structural measures, such as the massive execution of protected building parts and the reduction of the number of windows to sloping walls, are also recommended.

In addition, measures such as planting stone chip protection trees below rock walls can minimize the endangerment from falling stones. Young, bush -rich stocks are more effective compared to traditional high forests.

The population of Lesachtal is now dependent on the upcoming measures and the assessment of the state geologist to increase the level of security in the region and prevent possible further falling events.
