What effect does submarine volcanic eruption have on ships?

On September 23rd, 1952, a volcano erupted near a reef 416.7 kilometers south of Tokyo, Japan. A research ship from Japan Maritime Defense Agency first came here and found a new island on the sea, with an altitude of 3 meters and a diameter of 15 meters.

a few days later, the island disappeared, but the crater continued to spray, lava flowed into the sea, and steam turned into clouds and rose to the sky.

At this time, a hydrological research ship of Tokyo Fisheries Research Institute approached the volcanic eruption area again. Just as the crew on board began to take photos, measure the power of the volcano and select local water and soil samples, the volcano erupted for the second time, and the research ship was immediately swallowed up by steam and ashes. After the volcanic spray was scattered, there was no trace of the ship on the sea. It was not until a long time later that the wreckage of the ship was found.
