(BIVN) – The lava tube at the Kamokuna ocean entry broke open recently, spreading rivers of flowing lava all over the bench, according to lava boat tours.

Shane Turpin of Lava Ocean Tours called it “a sight to see”, sharing video of the new activity on Facebook.

Overall, its not a big change for the 61g lava flow, which is still active and forming a lava delta at Kamokuna.

“As of May 31,” scientists with the USGS Hawaiian Volcano Observatory wrote on Thurday, “the new lava delta was approximately 3.2 acres in size, extending about 100 m (328 ft.) out from the sea cliff.”

USGS also reminds the public of the dangers near the ocean entry on a daily basis:

The ocean entry is a hazardous area. Hazards include walking on uneven, glassy lava flow surfaces and around unstable, vertical sea cliffs. Venturing too close to an ocean entry on land or the ocean exposes you to flying debris from sudden explosive interaction between lava and water. Also, the lava delta is unstable because it is built on unconsolidated lava fragments and sand. This loose material can easily be eroded away by surf, causing the new land to become unsupported and slide into the sea. This occurred most recently on May 3. In several instances, such collapses have also incorporated parts of the older sea cliff. Additionally, the interaction of lava with the ocean creates a corrosive seawater plume laden with hydrochloric acid and fine volcanic particles that can irritate the skin, eyes, and lungs.”

None of these flows poses any threat to nearby communities at this time, scientists say.
