I have several friends in that area.
The first mail came this afternoon of friends travelling for half a year in South India (they are travel book writers). It looks as if in the place where they were (near Pondicherry) they saw nothing like a big wave- but the saltwater came upstream in the rivers and they met people fleeing from the coast- very chaotic while elderly people just stay in their endangered villages disoriented.

They don't have an overview over the situation just wanted us to know that they are ok.

I will try to contact another friend of ours who lives in Singapore but usually spends the holidays in his house at the Sri Lankan South coast, on the beach. I heard about the Sri Lankan East Coast and I hope the Galle region is not as much destroyed.

It is too too bad- nature (as in hurricanes or seaquakes) is something mankind can never manage.
