There is a thread from January of this year about the story.  The big thing they say is that the waves were diverted, miraculously, away from the Cathedral, parted at a wooden post said to have been placed where it is by St. Thomas, himself.:

CHENNAI (ICNS) – The tsunami waves have subsided, but a miracle is being talked about across Chennai. It is the story of how St Thomas’ miraculous post kept the invading waves away, sparing the newly renovated Santhome Cathedral.

The Cathedral, the world’s second basilica built on an apostle’s tomb, has been giving shelter to hundreds of tsunami victims ever since the waves ravaged many buildings across the coast.

But even though the killer tsunami waves devastated the Chennai coast, Father Lawrence Raj, the parish priest of the Santhome Cathedral Basilica, says “the sea did not touch our church.”

The reason? “We believe the miraculous post of St Thomas prevented the sea waters from entering the church,” says Father Raj.
