III.6.2.5 Lokasi Bencana Geologi
Dari segi kebencanaan, daerah lokasi PLTM Pagerpelah ini termasuk daerah yang rawan terjadinya gempabumi dan tanah longsor karena kondisi geologi local (jenis batuan) dan posisi tektoniknya relative dekat dengan zona-zona sumber.
Kondisi geologi setempat (jenis batuan) yang berupa perselingan antara serpih dan napal sangat peka terhadap udara (kering dan basah), sehingga kondisi batuan yang keras dalam waktu singkat (tidak lebih dari 1 bulan), kalau terbuka cepat mengalami kerusakan (slacking).

Gambar III 24 Tebing sungai (sebelah timur lokasi powerhouse) yang merupakan perselingan antara serpih dan napal yang cenderung longsor
Ditinjau dari segi kebencanaan lokasi rencana PLTM Pagerpelah merupakan daerah yang rawan terhadap tanah longsor, terutama pada lokasi yang kondisi batuannya merupakan perselingan antara serpih dan napal yang mempunyai sifat slacking yang tinggi.
Untuk mengurangi terjadinya longsoran, pada lokasi yang batuannya merupakan perselingan serpih dan napal supaya dibuatkan drainase yang baik dan permukaan galian (lereng) harus diproteksi (dengan gebalan rumput, bronjong maupun beton semprot).

III. the geological disaster site 6.2.5
disaster in terms of its location, the area includes Pagerpelah PLTM-prone areas of gempabumi and landslides due to local geological conditions (sandstone) and position tektoniknya relative close to the zones of geological Conditions.
source of local (sandstone) in the form of flakes and perselingan marls is extremely sensitive to air (dry and wet), hard rock conditions so that in a short time (no more than 1 month), if the quick open suffered damage (slacking).

Picture III 24 Cliff River (East of the location of the powerhouse) which is a perselingan between the flakes and marls are likely landslide
disaster in terms of site plan Pagerpelah PLTM is prone to landslides, especially on the rock conditions location is perselingan between the flakes and marls which have the nature of slacking.
to reduce the occurrence of avalanches, the location that the rock is shale and marl perselingan made so good drainage and surface excavations (slope) must be protected (by gebalan grass, bronjong or concrete spray).

III.6.2.5 Geological Disaster Site
In terms of disaster, local micro power Pagerpelah locations include areas prone to earthquakes and landslides because of local geological conditions (rock type) and tectonic position relatively close to the source zones.
condition of the local geology (types rocks) that form between the shale and marl perselingan very sensitive to air (dry and wet), so the rocks are harsh conditions in a short time (no more than 1 month), if opened quickly damage (slacking). Riverbanks Figure III 24 ( powerhouse location east) which is perselingan between shale and marl which tend landslide disaster In terms of micro power plan Pagerpelah location is an area that is prone to landslides, especially in locations that condition is perselingan between shale rock and marl which has properties of high slacking. To reduce the occurrence of avalanches, the location of the rock is shale and marl perselingan so made ​​good drainage and excavation surface (slope) should be protected (with gebalan grass, concrete or gabion spray).
