FLOOD

Floods in Malaysia are regular natural

disasters in Malaysia which happen

nearly every year during the monsoon

season.

CAUSES

• Given Malaysia's geographical location, most floods that occur are a natural result of cyclical monsoons during the local tropical wet season that are characterised by heavy and regular rainfall from roughly October to March.

• Inadequate drainage in many urban areas also enhance the effects of heavy rain, though efforts are underway to resolve

• Floods in Southern Johor was believed due to recent Global Warming effect. This is because Johor is not within the usual monsoon affected zone.

LANDSLIDES

Landslides in Malaysia are regular

natural disasters in Malaysia

which happen at the hillsides.

CAUSES

Deforestation due to uncontained development of hillslope areas are partly the cause of a majority of landslides in Malaysia. There were some instances where the development projects at hill sites were abandoned for a considerable period, affecting the maintenance of the slopes could causing them to collapse.

HISTORY• 1 May 1961 - A landslide occurred in Ringlet, Cameron

Highlands, Pahang.• 21 October 1993 The man-made Pantai Remis landslide

caused a new cove to be formed in the coastline.• 11 December 1993 - 48 people were killed when a block of the

Highland Towers collapsed at Taman Hillview, Ulu Klang, Selangor.

• 30 June 1995 - 20 people were killed in the landslide at Genting Highlands slip road near Karak Highway.

• 6 January 1996 - A landslide in the North-South Expressway (NSE) near Gua Tempurung, Perak.

MEASURES TO REDUCE LANDSLIDES

Immediate action has been taken and is being planned by the federal government to help remedy landslides problems in Malaysia. Such actions include:

• The construction of the retaining wall• Plant more trees along hillsides• Make sure to build houses on firm ground

ACID RAIN

Acid rain is a rain or any other form of precipitation that is unusually acidic, elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals, and infrastructure through the process of wet deposition. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxides which react with the water molecules in the atmosphere to produce acids.

Processes involved in acid deposition (note that only SO2 and NOx play a significant role in acid rain).

TSUNAMI

• Malaysia was affected by the indian ocean earthquake on 26 December 2004.

• The country's worst affected areas were the northern coastal areas and outlying islands like Penang and Langkawi.

• The number of deaths currently stands at 68 with 52 in Penang, 12 in Kedah, 3 in Perak and 1 in Selangor.
