Velankanni was among the worst hit by the massive 26 December
tsunami that was triggered by the
2004 Indian Ocean earthquake. The tsunami struck at around 9.30 am on Sunday, when pilgrims from
Kerala were inside the church attending the
Malayalam Mass. The rising water level did not enter the shrine, but the receding waters swept away hundreds of pilgrims who were on the beach. The shrine's compound, nearby villages, hundreds of shops, homes and pilgrims were washed away into the sea. About 600 pilgrims died. Rescue teams extricated more than 400 bodies from the sand and rocks in the vicinity and large number of unidentified bodies were buried in mass graves. ==Geography==
