[clarification needed], The filling (impounding) of reservoirs has often been attributed to reservoir-triggered seismicity (RTS) as seismic events have occurred near large dams or within their reservoirs in the past. When it was completed it was said to be the largest brick built underground reservoir in the world[11] and it is still one of the largest in Europe. Additionally, water must be able to infiltrate the deep rock stratum as the weight of a 100 m (328 ft) deep reservoir will have little impact when compared the deadweight of rock on a crustal stress field, which may be located at a depth of 10 km (6 mi) or more.[43]. © 1996 - 2020 National Geographic Society.
