Nov 16, Colombo: Sri Lanka Medical Research Institute (MRI) has commenced investigations to ascertain the cause of the red rain received by several parts of the island.
Director General of MRI Dr. Anil Samaranayake said the MRI has received the samples of rainwater collected from the areas where the red rain was reported.
Red rain was reported on November 14 from Sevenagala area and on November 15 from Moneragala and Manampitiya areas in the southeastern parts of the island.
No damage to life or property has been reported due to the unusual rain.
Increase in the acidity of the air and sand storms are the usual reasons for red rain. Sri Lanka does not get sand storms.
Dr. Samaranayake said similar rains were reported from Kerala of India in 2001 and most recently in June 2012 and recently released reports said that the rainwater got red color possibly due to spores of algae or similar organism.
