KEJADIAN TANAH RUNTUH

PERKAMPUNGAN ORANG ASLI SG.

RUIL, CAMERON HIGHLANDS

PAHANG DARUL MAKMUR

CASE STUDY

Banyak faktor boleh mencetuskan kejadian tanah runtuh

(Zul Baharin Shaari – 10.08.11)

Kejadian tanah runtuh boleh disebabkan oleh :

i. Faktor alam - jenis tanah, bahan dan ketebalan, geomorfologi,

pemendakan, dan kecuraman cerun.

ii. Faktor aktiviti manusia - pengubahsuaian cerun, bentuk saliran,

puncak cerun tidak seimbang dan aktiviti pemindahan secara ketara

tumbuh-tumbuhan di kawasan cerun.

Menteri Besar Pahang Datuk Seri Adnan Yaakob

"Saya difahamkan mengikut laporan awal, di atas bukit terjadi takungan air,

oleh kerana air terlampau banyak, hujan lebat, akhirnya tanah runtuh,"
