Friday Flotsam: Indonesia "ready to erupt", cryovolcanism on Enceladus and Kamchatka keeps rolling

A quickie post, but there were a few things too good to pass up:

Twenty Indonesian volcanoes "ready to erupt": Ralph at the Volcanism Blog has a great new post today about a report in the Jakarta Globe claims that at least twenty volcanoes in Indonesia are "ready to erupt". This is supposedly based on a report by the the head of the Indonesian Institute of Volcanology and Mitigation of Natural Disasters that has raised the alert status at 17 volcanoes from 1 to 2. Now, as Chris Rowan from Highly Allochthonous pointed out in a tweet, these volcanoes are not likely any more "ready to erupt" than they were last year. However, as with any random distribution of events, sometimes the said events will appear to "cluster", like the activity currently in Indonesia. You can see a great map of the alert status of all the Indonesian volcanoes here - but my guess is that what this might reflect is better monitoring on the part of Institute of Volcanology and Mitigation of Natural Disasters rather than a volcanopocalypse.

Volcanoes on Enceladus: Now, to take our focus from, well, Earth, I saw this great image this morning of 4 plumes on Saturn's moon Enceladus taken by the Cassini probe. These plumes are products of the abundant cryovolcanism on the moon - where water and other volatile materials are erupted much the same as ash is on Earth. In a sense, they are "super geysers" that form from the melting of the icy material inside Enceladus and the source of the heat is likely the tidal energy on the moon from Saturn.

The plumes of Kamchatka: Back on Earth, the NASA Earth Observatory posted a new image of two Russian volcanoes and their plumes - specifically Shiveluch (towards the top) and Kluichevskoi (aka Klyuchevskaya; at the bottom). I recently talked about the source of the abundant volcanism on Kamchatka, and the peninsula just keeps chugging along.

A bionic lens undergoing clinical trials could soon give you superhuman abilities

We're talking Ghost in the Shell type of stuff. 


Maybe you watched Ghost in the Shell and maybe afterwards you and your friend had a conversation about whether or not you would opt in for some bionic upgrades if that was possible - like a liver that could let you drink unlimitedly or an eye that could give you superhuman vision. And maybe you had differing opinions but you concluded that it's irrelevant because the time to make such choices is far in the future. Well, it turns out, it's two years away.

The philosophy of tragedy & the tragedy of philosophy - with Simon Critchley

Tragedy in art, from Ancient Greece to Breaking Bad, resists all our efforts to tie reality up in a neat bow, to draw some edifying lesson from it. Instead it confronts us with our own limitations, leaving us scrabbling in the rubble of certainty to figure out what's next.
