Kolkata and parts of West Bengal were on Wednesday rocked by successive mild tremors in a span of less than two hours, following the massive temblors in Sumatra. The first tremor was felt at 2.42 pm and the second at 4.13 pm, said Regional Meteorological Centre Director G C Debnath. Tremors were also felt in North and South 24 Parganas districts adjoining Kolkata and in Darjeeling and Siliguri in north Bengal, official reports said.
Heavy overnight rains lashed Kolkata leading to water-logging in many parts and slow traffic movement.
