Emaar Mgf Land — many cracks in flat due to mild earthquake

Address: Gurugram

Lot of cracks have been noticed in my 3-4 year old constructed flat. It was shocking to know from my tenants that multiple cracks were noticed
After an earthquake of scale 3.4 on may 10 2020. Even 2-3 tiles fall down from the roof, luckily no one was injured. It is really a blow to me as emaar is known for its quality. I myself live in delhi and have not heard from anybody that there was such damage in anyone's property. I have complained to the local maintenance staff, according to them it does not come under their purview. And could solve the problem by just using wall putty.
Who will be responsible if anything major happened. Is your structure so weak that it could not bear mild tremors?
Kindly look into the matter and do the needful.
