Thu Sep 19 08:25:03 UTC 2024: ## Sumisu Island Placed on Eruption Alert After Discolored Water Detected
**IZU, Japan (News On Japan)** – An eruption alert has been issued for Sumisu Island in the Izu Islands following the detection of discolored water near the island’s coast. This is the first time such an alert has been issued for Sumisu Island since observations began.
The Japan Meteorological Agency (JMA) confirmed a large discolored water area stretching approximately 1,800 meters from the island’s northwest to north coast during an aerial survey on September 18th. This follows a similar phenomenon observed in July, where discolored water extended about 300 meters from the island’s east coast. The expanding area has prompted the JMA to issue the eruption alert.
Authorities are warning of potential underwater volcanic activity around the island and the possibility of floating debris, such as pumice, resulting from an eruption. The Japan Coast Guard has issued a navigation warning for nearby waters, urging ships to exercise caution.
