Iceland: restless Hekla ‘ready to erupt’?

3 years agoAcademics / Geology : Volcanism

Seismic activity detected beneath Iceland’s Hekla volcano over the past few days appears to be the result of magma movement, according to Páll Einarsson of the University of Iceland, suggesting that the volcano could be heading towards eruption. The news agency AFP reports: ‘The movements around Hekla have been unusual in the last two to [...]

The Daily Volcano Quote: Victoria’s volcanoes

3 years agoAcademics / Geology : Volcanism

Victoria has probably more extinct volcanoes than all the other [Australian] states put together. … When white men came here little more than 100 years ago they found no legends among the blacks about the extinct volcanoes having been active. These were all cold before the arrival of the human being. We must be grateful [...]

Prof warns of volcanic threat to south-east Australia: that word ‘overdue’ again

3 years agoAcademics / Geology : Volcanism

Professor Bernie Joyce of Melbourne University is warning, again, that south-east Australia is ‘overdue’ for a volcanic eruption – ‘well overdue’, in fact, according to the report, headlined ‘Victoria’s overdue for volcano – warning’, in Melbourne’s Herald-Sun newspaper: Scientists have told a conference it is only a matter of time before volcanoes erupt in Victoria, [...]

The Daily Volcano Quote: volcano gods in Japan

3 years agoAcademics / Geology : Volcanism

Though Japan has one hundred volcanoes, of which half are more or less active, the feelings excited by volcanic phenomena have left little trace in the religion. The Kojiki, Nihongi, and Norito do not recognize any worship of volcanoes. Perhaps the Aso-tsu-hiko and Aso-tsu-hime of the Nihongi are to be reckoned an exception. These are [...]

The Daily Volcano Quote: volcanoes the safety valves of the globe

3 years agoAcademics / Geology : Volcanism

We regard the existence of volcanoes as evidential of divine benevolence … we refer now to active and not extinct volcanoes. And these, we are aware, are almost universally regarded as exhibitions of the displeasure of God, rather than of his benevolence. It is indeed true, that they are often terrific exhibitions of his power; [...]

Puyehue-Cordón Caulle corked: a small-scale case-study of media sensationalism

3 years agoAcademics / Geology : Volcanism

Even by the standards of sensationalized volcano stories in the mainstream media the headline in the Sydney Morning Herald and some other news sources today is pretty silly: ‘Red alert as “cork” plugs volcano’. This headline does what such headlines so often do: create a false sense of an urgent, dangerous situation by misrepresenting the [...]

A note on comments

3 years agoAcademics / Geology : Volcanism

A small number of highly partisan and very un-volcanological posts have been left here in response to the Nabro eruption: Eritrean politics is clearly a very divisive business. Most of these comments were automatically held for moderation and did not make it through in the end — this affected arguments from both pro- and anti-government [...]

The Daily Volcano Quote: the power of Etna’s lava

3 years agoAcademics / Geology : Volcanism

Among the many eruptions of this volcano, the one in the year 1669, deserves to be recorded.

The Daily Volcano Quote: uses of a lava flow

3 years agoAcademics / Geology : Volcanism

The large crater of San Salvador volcano contained a crater lake in the early 20th century. However, in June 1917, the lake boiled away in the same week that an earthquake did considerable damage to cities on all sides of the volcano, and lava began to flow from the volcano’s north side … The lava [...]
