The 1977 Andhra Pradesh cyclone was a devastating tropical cyclone that hit Andhra Pradesh in November 1977, killing at least 10,000 people. The worst affected areas were in the Krishna River delta region. The island of Diviseema, which was hit by a seven-metre-high (23-foot) storm surge, experienced a loss of life running into the thousands. The large loss of life prompted the establishment of early warning meteorological stations on the coast of Andhra Pradesh. Cyclone shelters and other measures for disaster management were also taken. A memorial, at the point of furthest advance of the tidal wave, near the town of Avanigadda, was built in memory of the people who died in the storm.
