A series of “small water explosions” were detected on Whakaari / White Island yesterday.

Science agency GNS detected the low-energy explosions making use of seismic and acoustic air difficulty sensors at the island.

They occurred at 3pm on Tuesday – and experienced short-lived, lasting about 30 minutes, the main agency said.

At least 20 individual pulses came about, which may have produced “minor traces” of ash near the vent number of minutes.

MetService’s satellite images didn’t detect a ash in the atmosphere, it rumoured.

Meanwhile, visions from the island’s webcam suggested far vigorous pulses of steam might well have come from the active vent of the volcano at the time, GNS said.

Activity has since taken back to a low level, it said. I would say the island’s volcanic alert level continues as at 1 and the aviation colorations code will stay “green”.

“While Volcanic Alert Rank 1 is mostly associated with environmental people from france, eruptions can still occur with little or no warning. ”

The lowest alert level is 0, classed as “no volcanic unrest”. Level 1 means “minor scenic unrest”.

Number one hazards of alert level – include discharge of steam and as a result hot volcanic gases, earthquakes, landslides and hydrothermal activity.
