Mystery Volcano Photo #26

When we last left MVP, the latest entry actually did give people some trouble – but Don Crain ended up landing the winner at guess #15. The volcano is Ollagüe along the Chilean/Bolivian border. I took this shot from the road that comes up from the south towards Ollagüe (the town). Now, I have been…

Climate, volcanism and the Andes

The northern Chilean and southern Peruvian Andes are full of volcanoes that look stunning – I mean, jaw-dropping details of volcanism litter the landscape. The reason for this is two fold: (1) there is an awful lot of volcanism in the northern Chilean/southern Peruvian Andes (as known as the Central Volcanic Zone) – and has…

So, I’ve had requests on the blog to help to do some defining of volcanologic terms on the blog, so I thought I’d try a new column called Eruptions Word of the Day. I’m not sure how often it will run, but let’s give it a try. Eruptions Word of the Day for July 5,…

For example, there are quite a few volcanoes in the Chilean Andes that erupt dacite lavas, which are relatively viscous (sticky), so you might expect it to erupt explosively. However, you can…

Extremophiles, Volcanoes and You

Folks have been suggesting that life on Earth started near volcanic vents for a long time now (and of course, some people don’t buy it). Whether or not life sprung forth near hydrothermal vents, undersea black smokers or from the head of Zeus, it doesn’t really change the fact that we find organisms living in…
