HAWAII volcanic ash fallout forecasts paint a bleak outlook for the residents of Big Island. Officials have now raised concerns volcanic gas emissions in Leilani Estates have doubled over the last two weeks.

Volcanic gas emissions in the Lower East Rift Zone remain very high, authorities have warned, after worrying weekend measurements.

The United States Geological Survey (USGS) found gas emissions from volcanic Fissure Eight in Leilani Estates have almost doubled in a fortnight.

Unfortunate wind conditions are expected to exacerbate the conditions and deliver vog, an acidic cocktail of volcanic gases, to the south and west sides of Big Island.

The unofficial USGS forecast map shows a narrow area of volcanic ash fall from the Kilauea Halemaumau crater extending in a southwest direction.

The agency predicts Kilauea’s smokestack could reach up to 11,150 feet in height and last around 30 minutes.

Trace amounts of volcanic ash could reach up to 10 miles southwest of the town of Pahala, covering the ground with up to 0.1mm of ash.

More “substantial” fallout up to 6mm thick would be limited to an area in the immediate vicinity of the Hawaii volcano.

The ash fall predictions were mathematically modelled on a May 17 eruption of Kilauea’s summit.

That eruption blasted the skies with ash, spewing thick smoke 30,000 feet high.

As of Sunday evening, 10.26pm Hawaii time or 9am UK time in Monday, there have been no ash emissions from the summit but seismic activity is on the rise.

The USGS said: “If the pattern observed before previous explosions persists, we expect another event in the next few hours.
