Titiwangsa Mountains
The Titiwangsa Mountains (Malay: Banjaran Titiwangsa; Jawi: بنجرن تيتيوڠسا, pronounced [ˈband͡ʒaˈran titiwaŋˈsa]), also known as Banjaran Besar (lit. 'main range') by locals, is the chain of mountains that forms the backbone of the Malay Peninsula. The northern section of the range is in southern Thailand, where it is known as Sankalakhiri Range (Thai: ทิวเขาสันกาลาคีรี; RTGS: Thio Khao Sankalakhiri; pronounced [tʰīw kʰǎw sǎn.kāːlāːkʰīːrīː]).

The mountain range acts as a natural divider, dividing Peninsular Malaysia, as well as southernmost Thailand, into east and west coast regions. It also serves as a drainage divide of some major rivers of Peninsular Malaysia such as the Pahang, Perak, Kelantan, Klang and Muar. The length of mountain range is about 480 km from north to south.
Geology
The Titiwangsa Mountains is part of a suture zone that runs north–south, starting in Thailand at the Nan-Uttaradit suture zone (partly coincident with the Dien Bien Phu fault), and extending south towards Peninsular Malaysia (Bentong-Raub suture zone).[1] The eastern half of the Titiwangsa Mountains in Peninsular Malaysia is an amalgamation of continental terranes known as Cimmeria or Indochina, whereas the western half is an amalgamation of continental terranes Sinoburmalaya or Sibumasu. These two halves of terranes were separated by the Paleo-Tethys Ocean.[2][3]
The Cimmeria was separated from Gondwana around 400 mya during the Devonian and rifted towards Laurasia, the northeastern arm of Pangea. It attached to Laurasia completely around 280 mya during the Late Permian.
Sibumasu terranes on the other hand, only started to separate from Gondwana during the Early Permian and rifted towards Indochina. The collision of Sibumasu terranes and Indochina terranes during 200mya Late Triassic resulted in the closure of the Paleo-Tethys Ocean and formation of the modern Titiwangsa Mountain belts.
Seismic hazards
Peninsular Malaysia, while being tectonically stable, has a history of intraplate earthquakes,[4] with most of them are of low magnitude. As the Bentong-Raub suture runs parallel to the Titiwangsa Mountains, a large network of fault lines also crisscross the mountain range.[5] The known major fault lines in the mountains are the Bukit Tinggi, Kuala Lumpur and Seremban fault lines, with the first two being the most active.
Between 1984 and 2013, there had been tremors ranging from 1.6 to 4.6 on the Richter scale with local epicentres in Kenyir Lake, Manjung, Temenggor, Bukit Tinggi and Kuala Pilah, the latter three being situated along the Titiwangsa Mountains. As a precautionary move, the Department of Minerals and Geosciences pitched 23 Earthquake Benchmark (PAG, Malay: Penanda Aras Gempa) stations around earthquake-prone areas in Peninsular Malaysia, with 13 in Pahang, six in Selangor, and two each in Perak and Negeri Sembilan to monitor possible movements within the fault network.[6] The Ministry of Natural Resources, Environment and Climate Change (NRECC) also pointed out that strong earthquakes centred in neighbouring Sumatra, Indonesia could potentially activate ancient faults in Peninsular Malaysia and the effects of tremors could be felt around areas along the west coast of Peninsular Malaysia.
Geography
This mountain range is a part of the wider Tenasserim Hills system. It forms the southernmost section of the Indo-Malayan cordillera which runs from Tibet through the Kra Isthmus into the Malay Peninsula.[7]
The Titiwangsa Mountains begins in the north as the Sankalakhiri Range, a prolongation of the Nakhon Si Thammarat Range which includes the smaller Pattani, Taluban, and Songkhla sub-ranges. The Sankalakhiri marks the border between the Southern Thailand provinces of Yala in west and Narathiwat in the east. Across the border into Malaysia, the main stretch of the range runs in a northwest–southeast orientation, straddling the borders between the west coast states of Perak and Selangor with Kelantan and Pahang on the eastern side of the peninsula. From the tripoint of Pahang, Selangor and Negeri Sembilan near Mount Nuang, it then transverses through the middle of the state of Negeri Sembilan, also a west coast state, thus dividing the state into two regions - western Negeri Sembilan, which consists of Seremban, Port Dickson and Rembau Districts, and eastern Negeri Sembilan, composed of the districts of Jelebu, Kuala Pilah, Jempol and Tampin - and ends in the south near Tampin, in the southern part of the state. Clusters of inselbergs project further southeastward into Melaka and Johor, and most of them are topographically isolated from the mountain range.
The highest elevation is 2,183 m (7,162 ft) Gunung Korbu, Perak. On the Thai side the highest point is 1,533 m Ulu Titi Basah (ยูลูติติ บาซาห์), at the Thai/Malaysian border between Yala Province and Perak.[8] In the southern section of the range, the highest is the 1,462 m (4,797 ft) Mount Besar Hantu, on the border between Negeri Sembilan and Pahang.
Features
The rainforests of the Titiwangsa Mountains form part of the Titiwangsa Forest Complex, which is itself part of the larger Central Forest Spine conservation area.
Several popular tourist destinations such as Royal Belum, Cameron Highlands, Genting Highlands and Fraser's Hill are located on the range.
Two of Malaysia's largest metropolitan areas are located along the western fringes of the mountain range, namely Greater Kuala Lumpur (ranked #1) and Kinta Valley (ranked #4). The Kinta Valley Geopark encompasses the entirety of Kinta Valley, where kegelkarst topography is prevalent.
A number of roads and highways cut through the mountain range, effectively acting as mountain passes linking both settlements on both sides of the range.

In popular culture
The mountain range was the subject of the patriotic song "Titiwangsa", which was first sung by Saloma. Its lyrics glorifies the magnificence and beauty of the Titiwangsa Mountains, and its significance to Malaya as a whole.
