Images have emerged showing the sea water at Sam Son divided into two colors.
Images of the seawater in Sam Son, Thanh Hoa, divided into two distinct colors have attracted widespread attention after a video clip capturing this scene went viral on social media on July 13, 2025.
According to a representative of the Sam Son Ward People's Committee, this is a frequently occurring natural phenomenon, especially after heavy rains, due to the beach's location near the mouth of the Ma River. River water carrying sediment from upstream flows into the sea, creating a distinct color boundary when it meets seawater.
The clip, filmed with a drone at around 4 PM on July 13th, captured the impressive image of the sea surface divided into two colors, quickly sparking curiosity and discussion on online platforms.
Many locals assert that the phenomenon is nothing unusual. Over the years, the area has repeatedly experienced the phenomenon of two different colored seawater, especially after heavy rains. According to authorities and residents, the phenomenon of Sam Son seawater dividing into two colors is a natural occurrence that has happened frequently over the years.
