● A deadly landslide at Taman Bukit Permai 2 in early March claimed four lives, while a fifth victim suffered minor injuries.
Slope failure led to the landslide on March 10 and another on March 12, forcing the evacuation of residents from Taman Mega Jaya and Taman Bukit Permai 2.
Fifteen houses and 10 vehicles were also damaged.
The area was later declared a disaster zone, resulting in the evacuation of occupants from 48 houses along Jalan Teratai 1/2K, Jalan Teratai 1/2J and Jalan Mega 15.
On March 12, another landslide occurred at the same site and residents from an additional 22 houses in Jalan Bukit Permai 1 were asked to evacuate.
More than a month later, clean-up works to remove the debris are still being carried out, while short-term slope repairs are ongoing.
● A landslide in Kemensah Heights last year caused a ripple of concern in the community.
On Sept 17, the landslide affected three bungalows and 12 townhouses, forcing the evacuation of more than 100 residents. Fortunately, no casualties were reported.
Initially, Energy and Natural Resources Minister Datuk Seri Takiyuddin Hassan said illegal renovations by houseowners had triggered this.
But some have said the hill could have collapsed due to the diverging of Sungai Kemensah that flows at the foot of the hill.
Later, Environment and Water Minister Datuk Seri Tuan Ibrahim Tuan Man said the Drainage and Irrigation Department would carry out slope stabilisation and upgrading works at Sungai Kemensah, estimated to cost RM10mil.
● A deadly landslide in December 2008 at Taman Bukit Mewah, Bukit Antarabangsa was a catalyst for MPAJ to set up its Slope Unit a year later.
The landslide killed five people and destroyed 14 homes, forcing 2,000 people to be evacuated.
● Ampang was also the area of the Highland Towers collapse in 1993, which claimed 48 lives.
