Comment on Taiwan volcano: active, dormant, or what? by Alexander (Sasha) Belousov

The artice in the newspaper is based on our recent data about tephrostratigraphy of the region. The data have supplemented well-known geophysical ang geochemical data about existence of active magma chamber under the Tatun Volcanic group. We have got totally five C14 dates for the Tatun Volcanic Group, which indicated last explosive magmatic eruption ~ 13 000 calendar years ago, and last phreatic eruption ~6 000 years ago. Major pyroclastic flow was formed ~ 25 000 years ago. Our paper with the data was recently submitted to JVGR, and will be presented at AGU in December. Nuclear power plant is located 2 km from the nearest lava flow. Probability of reactivation of the volcano in the nearest future is very low, and there is absolutelly no reason to panic. But there is reason to install modern monitoring equipment , as well as elaborate actions of scientists and government officials for the case if signs of volcanic unrest will be registered.

Comment on New Australian volcano may pop up in Ballarat area, warns geologist by baz

Well, no harm whatsoever in you learning to deal with the medical consequences of volcanic eruptions, but you are far more likely to be directly using the skills you learn in, say, one of the volcanically active Pacific islands than here in Australia. The threat here is very remote, compared to fires or manmade pollution or epidemics … The Mexican parallell isn’t a good one: the volcanic fields where Jorullo and Parictutin emerged were showing themselves to be active in ways that just aren’t happening in SE Australia. As for the supervolcano … not everywhere where there has ever been volcanic activity is a potential supervolcano, whatever the media may like you to think!

‘If one goes they all go’ … what is the evidence for that, exactly?

If one goes they all go. Like monkey see monkey do, or a chain reaction, if Ballarat or Anakies go up so the rest may follow including Mt Gambier and the others in the Western & Northern Victoria’s volcanic provinces

What happens if the volcanic province Western Victoria turns out to be a super volcano? a new volcano can come up as I know any where in the area not just ballarat, all you need is a sniff of sulfur or smoking fumoles from a farm some where (one happened in Mexico). I am a student paramedic at Vic Uni and I do understand that I will most certainly have to learn to deal with volcanic eruptions.

Thank you to Henry Gaudru for the note about Piton de la Fournaise. I haven’t time to write anything up now, but will catch up with events on Reunion as soon as I can. In the meantime, Erik Klemetti has a report at his Eruptions blog:

Piton de la Fournaise – Reunion Island – France

As of the 6th of November OVPLF reported that following a short seismic crisis yesterday evening between 7:30 pm – 8:30 pm then a 30 mn of pause, a signal of tremor occured and a new eruption started at 9 pm (GMT + 4). The lava has issued from the East flank of the Dolomieu crater as lava fountains and lava flows.Scientists carried out an flight over the voclano at 6:45 am (GMT 4) with the helicopter allowed to confirmed that two fractures opened in the south, south side is and is of the crater sommital Dolomieu. Each of the cracks let escape a lava flow reaching the elevation of approximately 1970 metres. At 7:30 am on the morning, lava flows were not any more fed, consequence of a progressive decrease of the intensity of eruptive trémor since 3:00 am this morning ( GMT+4). At 9:00 am (GMT 4) the eruptive trémor was practically non-existent. (From OVPLF)

Konstantinou et al mention the close proximity of the nuclear plants in their 2007 paper, cited above. In fact there are two nuclear power plants close to Tatun, Kousheng and Chinshan (two reactors each):

Considering the risk posed by Tatun volcano, nobody is mentioning the presence of a nuclear power plant (Kuosheng) at about 6-7km from the crater! As far as I know, this is the only example of such vulnerability on earth.
