Concern & curiosity grip Vizag as sea recedes by 100 m

A rare and surprising event occurred at RK Beach in Visakhapatnam, where the sea unexpectedly receded by up to 100 metres on Sunday. This unusual occurrence left stones that are normally submerged exposed, causing a mix of panic and curiosity among locals and tourists.
The sudden drop in sea level offered a unique chance for visitors to explore areas usually covered by water. Tourists, such as Ram Naidu from Srikakulam, took advantage of the low tide. “We have visited several times before, but we could never climb the stones,” Naidu remarked. “This was a unique experience for us.”
However, this unusual sight also raised concerns among residents, who feared it could be a sign of a potential tsunami. Historically, significant drops in sea level have been linked to natural disasters, which heightened fears among coastal communities.
To address these concerns, Dr BSR Reddy, a retired oceanography professor from Andhra University, offered some reassurance. Speaking to The Pioneer, Dr Reddy explained that such events are often due to natural, seasonal changes. “Tides are the periodic rise and fall of sea levels caused by the gravitational forces of the moon and sun,” Dr Reddy said. “During low tide, the sea level appears to retreat, which is a normal occurrence. This usually returns to normal within a day or two.”
Dr Reddy also mentioned that extreme weather events, such as cyclones, can affect sea levels. “Storm surges from cyclones, even those affecting nearby regions like Odisha, can temporarily alter sea levels,” he added. “Additionally, changes in ocean temperatures can cause variations in sea levels. Warmer waters expand and increase sea levels, while cooler waters contract and lead to a temporary drop.”
While the unusual sight attracted curious tourists and provided a chance for exploration, experts advise the public to stay informed and cautious. According to Dr Reddy, such occurrences are generally part of natural tidal patterns.
