Two of the four illegal apartment complexes were brought down by controlled implosion here on Saturday.
However, the other two apartments-- Golden Kayaloram and Jain Coral-- will be demolished on Sunday.
The demolition of the first building Holy Faith H2O, slated to be carried out at 11 am, was delayed by 18 minutes while the twin towers of Alfa Serene, which is surrounded by 36 houses, were brought down at 11.43 am.
As per authorities, as many as 343 kgs of explosives were used for the demolition of twin towers of Alfa Serene, which had 80 apartments and 16 floors each.
Section 144 has been imposed within a 200-metre radius of the complexes on Saturday and Sunday. Moreover, traffic has been halted on land, water and air in the evacuation zone during the process.
There are concerns that some concrete pieces of the second tower of the building may have fallen into the lake nearby. It is yet to be estimated if the debris or concrete pieces have affected the buildings nearby.
The four apartment complexes in Maradu were ordered to be demolished by the Supreme Court for violating the Coastal Regulation Zone (CRZ) norms.
