The effusive eruption at the volcano continues.
Active lava ooze outs continue to build the island where tongues of lava flows, spreading into various directions, enter the ocean and form gas-steam emissions at interaction with lava and water. Steam-laden plumes reach 1-2 km above the island.
The island is currently (19 September) measured by 211 meters arranged in the north-south direction and by 218 meters in the east-west direction with a total surface area of about 8.6 acres and estimated height of 15 meters above sea level.
Mariners are advised to stay 4 km away from the volcano.
