The volcanic island Whakaari / ‘White Island’ in New Zealand’s north-eastern
Bay of Plenty. Erupted on 9 December 2019. There were 47 people on the
island at the time. Twenty one people were killed, including two
who are missing and declared dead, and a further twenty-six
people suffered injuries, many of whom suffered severe
burns. The ongoing seismic and volcanic activity
in the area as well as heavy rainfall, low
visibility and toxic gases hampered
recovery efforts over the week
following the incident.
White Island New Zealand – December 2019
Extract from ‘Geology & Hazards’ – Volcanic Gases:
… Gases are continually emitted from the craters and fumaroles on White Island, at rates of several hundred to several thousand tonnes per day. These gases are mostly steam, carbon dioxide and sulphur dioxide, with small quantities of halogen gases (chlorine and fluorine). The acid gases combine with water in the steam/gas clouds to form liquid acid droplets which sting the eyes and skin, and affect breathing. They also severely damage cameras, electronic equipment and clothing. Visitors to White Island should avoid steam/gas clouds, and watch for wind changes that could blow clouds in their direction.
Gas masks with acid gas filters are advisable … MORE

“… I am interested that reporters are not discussing
Hydrogen Fluoride gas emissions from this volcano.
It is known to emit 1500 to 2000 kilogram of HF gas each day,
when it is in its ‘quiet’ mode. Hydrogen fluoride inhalation
has caused death in numerous industrial accidents
usually within 24 hours and burns to the skin
from this gas have claimed victims some
days later ” Dr Geoff Pain ⇒ HERE
Here we describe for the first time the features of endemic fluorosis
in the Herculaneum victims of the 79 AD eruption, resulting from long-term
exposure to high levels of environmental fluoride which still occur today.
” Volcanic eruptions may also affect the climate, especially if there are
many large-scale eruptions over a short space of time which
add volcanic dust and fluorides to the atmosphere.”
Korea experienced a massive chemical dispersion disaster on 27th September 2012, which occurred at the Gumi National Industrial complex in the southern city of Korea. About 8 tons of hydrogen fluoride gas leaked as the valve of tank lorry was opened due to a operators mistake, resulting in 5 casualties and about 3,600 medical treatment, causing 17.7 billion KRW of damage to enterprises, and spoiling the crops on 323.8ha of land.
…Meanwhile, the clean-up near Gumi continues.
On 13 December, the government began burning about
9,100 tonnes of crops and trees killed by the gas,
leaving the scene of the accident even
more barren than before…

“…The imprint of plume-released fluorine
on rainwater chemistry and on water extractable
fluorine in soils is clearly detectable up distances of more
than 20 km from the summit craters in the downwind direction…”
