Abstract: 

The destructive geological processes in the Rhodopes region are typical for the territory of complex tectonic structure - horsts, grabens, fault zones, active neotectonic movements, mountainous relief and diverse engineering-geological conditions. The dominating role in the structure of the geological hazards belongs to the earthquakes, the slope processes (landslides, rock falls, screes, avalanches, creep) and to groups of phenomena related with urbanization, mine workings, hydrotechnical constructions. These are artificially provoked landslides in coal basins, dangerous gases in underground mines, rock shocks and sudden water currents in tunnels, pollution of water and soil by industrial waste, tailing ponds and dump-hills. All these numerous natural and manmade processes exert negative impact on the population, infrastructure and the environment, hampering the sustainable development of the area. Prevention and protection measures are necessary for decreasing the consequences of the geological hazards.

Ил. Бручев. Г. Франгов. Р. Вырбанов. Пл. Иванов. Геологические опасносты в западной nериферuи Родопского региона. Разрушительные геологические процессы в Родопском регионе типические для территорий сложным тектоническим строением – хорсты, грабены, разломные зоны с актывными неотектоническими и современными движениями, горный рельеф, разнообразные инженерно-геологические условия. В структуре геологической опасности ведущее место занимают землетрясения, гравитационные процессы (оползны, обвалы, ползучесть, лавины), а также явления, связанными с поверхностными и подземными водами (эрозия, грязевые потоки, карст, агрессивность воды). Значительной доли занимают процессы и явления, связанными с урбанизаций, горными работами, гидротехническим строительством. Это антропогенные оползны в уголных бассейнах, опасные газы, скальные удары и внезапные водопроявления в подземных выработках и тоннелях, загрязнение воды и земли промышленными отходами, хвостохранилищами, отвалами битовых отходоп. Весь этот набор естестпенных и антропогенных процессов оказывает отрицательное воздействие людям, инфраструктуре, окружающей среде и замедляет развитие области. Необходимо принимать предохранительные и защитные меры для уменьшения последствий геологической опасности.
