Did Logging Activities, Development Cause Mudslide On KL-Karak Highway?


KARAK (Saturday, 14 November 2015) - The Sultan of Pahang has refuted allegations that the mudslide at KM52.4 of the KL-Karak Highway on Wednesday was caused by illegal logging on the hillslopes.

SultanAhmad Shah said there had been no reports of illegal logging in the area and the authorities had not informed him of any such activity.

 "There is no such thing. If there were, those responsible can be arrested, but so far I have not been informed of such activities," he said.


He was speaking after a two-hour visit to the site of the disaster where he was briefed on repair works and safety checks by authorities.

Accompanying Sultan Ahmad Shah was Transport Minister Datuk Seri Liow Tiong Lai, who is also Bentong member of Parliament.

Sultan Ahmad Shah also handed out aid to victims from the Lentang Forestry Department quarters whose homes were affected by the mudslide.

Sultan Ahmad Shah also refuted statements made by Works Minister Datuk Fadillah Yusof on Thursday, in which he said investigations by the Fire and Rescue Department and the Public Works Department found land-clearing activities on hill, which could have caused the formation of a waterlogged pool that eventually broke under pressure of constant rainfall, causing the mudslide.

"He should make statements based on facts, not speculation. I can tell you there is no illegal logging in this area," said Sultan Ahmad Shah.

Traffic will be allowed through the affected section of the highway from today and both lanes are affected to be fully operational by tomorrow.

The actual cause of the mudslide at the Kuala Lumpur-Karak Highway which resulted in thousands of motorists trapped on Wednesday will be investigated even though several parties did not rule out the incident might have been due to uncontrolled logging activities and development.

The  Association for the Protection of Natural Heritage of Malaysia (PEKA) is among those which believes the landslip at KM52.4 of Kuala Lumpur-Karak Highway near Lentang-Bukit Tinggi area was due to uncontrolled logging activities in the Lentang Forest Reserve area.

PEKA  believes that the mudslide at the Kuala Lumpur–Karak Highway was due to excessive logging and land clearing in Hutan Simpan Lentang and the surrounding areas. It said it had warned and pleaded with the authorities last year to stop the environmentally-damaging activities.

In a letter to Tenaga Nasional Bhd chief executive officer Datuk Seri Azman Mohd on Jan 20 last year, it protested against the project near Lentang, Pahang. Peka had detailed why it had to be halted immediately and what would happen if the project was continued. It warned of the ecological effects which would lead to the extinction of flora and fauna and how exposing the land to torrential rain could lead to river pollution, turn it murky brown and cause mud floods.

PEKA said there could be erosion of the riverbed and landslides. Copies of the letter were sent to Prime Minister Datuk Seri Najib Razak, Pahang Menteri Besar Datuk Seri Adnan Yaakob, Natural Resources and Environment Minister Datuk Seri Dr Wan Junaidi Tuanku Jaafar and others.

The highway concessionaire, ANIH Berhad also said rubbish, timber logs and boulders which were swept away in the incident near the Lentang Forest Reserve showed certain activities in areas outside of the company's maintenance site caused overflow of water.

However, Pahang Menteri Besar Datuk Seri Adnan Yaakob said the mudslide incident was due to natural causes but did not deny there were logging activities near the area.

The Pahang Forestry Department concurred with the statement and denied there was logging activities on the fringe of the Lentang Forest Reserve which caused the incident, and said the incident was due to heavy rain and slope failure in the area.

Nonetheless, Works Minister Datuk Seri Fadillah Yusof yesterday stressed that the cause of the incident would be investigated and its results would be announced in two weeks after the related experts completed their studies on the incident.

However, he said it was still too early to link the incident to logging activities as investigations had not been completed.

The mudslide near Lentang-Bukit Tinggi at 6.30pm on Wednesday (11th November 2012) caused a section of the highway impassable in both directions, with three private vehicles and a lorry stranded in the area. Fortunately, vehicle owners managed to run to safety.

The incident also caused 25 occupants of Pahang Forestry Department quarters to evacuate to the Lentang mosque.

Meanwhile, the Fire and Rescue Department has not ruled out the possibility of a second mudslide at the highway, should heavy rain continue.

Its deputy director-general, Datuk Soiman Jahid said the possibility was based on a survey from the air which showed there were pools of water at the hill top near the highway.

Meanwhile, The natural resources and environment ministry (NRE) has directed the Minerals and Geoscience Department to conduct a ground structural stability assessment in the hill area near the mudslide location at KM52.4 of the Kuala Lumpur-Karak Highway.

Minister, Datuk Seri Dr Wan Junaidi Tuanku Jaafar said this was to determine whether the area could withstand pieces of timber swept away by rain water.

He said the assessment report was expected to take between two and three weeks before it was submitted to the ministry.

"We must be very sure and detailed, and we are cooperating with the state forestry department.

"From our observation, we could see that an embankment built near the area had collapsed, and timber pieces were carried by the mudslide to the highway below," he told reporters after visiting the mudslide incident location in Bentong on Friday.

Wan Junaidi also visited occupants of the Pahang Forestry Department quarters who were temporarily sheltered at the Lentang Mosque after their quarters were inundated with mud water and struck by boulders from the mudslide on Wednesday.

The NewStraits Times today said that those plying routes where they could be exposed to life-threatening mudslides or debris flows can expect a heads up on any impending risks, as efforts are under way for the implementation of a multi-faceted warning system.

 Geological experts who have been working closely with the government in establishing the system said the move could be initiated after gathering data on risky zones in the country.

Authorities are, at present, collating data on the hazards and risks of slopes through a mapping process using Light Detection and Ranging (LiDAR) technology, a remote sensing technology that measures distance by illuminating a target with a laser and analysing the reflected light  to develop the public warning system.

Universiti Kebangsaan Malaysia Engineering Geology and Structural Geology associate professor Dr Tajul Anuar Jamaluddin said the slope hazard and risk mapping project, which was proposed to the authorities several years ago, was part of the process in developing the alert warning system.


Works Minister Datuk Seri Fadillah Yusof confirmed the development of the system. He told the New Straits Times last night that the ministry expected the system to be ready in two years.
