Lahars: an analysis of their role in losses from volcanic eruptions

A new paper from the University of Bristol (Brown et al. 2017) demonstrates the role that lahars play in causing loss of life in volcanic events

Threat to the ozone layer by future volcanic eruptions greater than previously thought

As the CFCs slowly degrade over the coming decades, so too should the volcano’s ozone-destroying power. However, new research shows that the volcanic risk to the ozone layer will persist for decades longer than previously believed.

La Palma – initial images of the “mega-landslide”

Over the weekend I was lucky enough to visit the island of La Palma. I have posted some initial images of the site of the Cumbre Vieja “mega-landslide

Mega-landslides as a vehicle for colonisation of distant islands

In a paper just published in the Journal of Biogeography, the authors propose that landslides play a key role in the transport of species between islands

Global warming could reduce volcanic cooling effects on climate

New research finds that as the climate warms, Earth’s atmosphere could trap more volcanic and plumes in the troposphere, the lower part of the atmosphere where weather happens. Volcanic aerosols that stay in the troposphere get washed out by precipitation in days or weeks.

Meru Volcano, Tanzania: the largest known continental debris avalanche

A new paper in the journal Landslides describes a 20 cubic kilometre landslide that occurred on Meru Volcano in Tanzania about 9000 years ago

A science story that just won’t die: the Canary Island Megatsunami scare rears its head once more

Like a zombie that refuses to die, the Canary Islands megatsunami scare story has once again re-emerged to the normal hysterical headlines

Dormant volcano near Rome is waking up

A long-dormant volcano outside Italy’s capital is entering a new eruptive cycle, a recently published study finds. Scientists previously assumed Colli Albani, a 15-kilometer (9-mile) semicircle of hills outside Rome, was an extinct volcano. But in recent years, scientists have observed new steam vents, earthquakes and a rise in ground level in the hills and surrounding area.

Music of the Earth

Stanford University’s Miles Traer, once again, is cartooning from the AGU Fall Meeting in San Francisco.


Volcano pressure guns show how rocks spew and eruptions ensue

The vinegar volcano is a stale science experiment. But Italian geologist Valeria Cigala takes the tired demonstration to a violent new level…

The latest on magnetics

This is the latest in a series of dispatches from scientists and education officers aboard the Schmidt Ocean Institute’s R/V Falkor. The crew is on 36-day research trip to study Tamu Massif, a massive underwater volcano, located 1,500 kilometers (930 miles) east of Japan in the Shatsky Rise. Read more posts here.

We are currently mapping our last survey line on Tamu Massif, and we will soon be ready to head out. The planetary Kp index, used to characterize the magnitude of geomagnetic storms, says the magnetic field is a little unsettled.

End of days

This is the latest in a series of dispatches from scientists and education officers aboard the Schmidt Ocean Institute’s R/V Falkor. The crew is on 36-day research trip to study Tamu Massif, a massive underwater volcano, located 1,500 kilometers (930 miles) east of Japan in the Shatsky Rise. Read more posts here.

As the end of Magnetic Anomalies expedition draws near, we will soon complete our exploration over Tamu Massif, the World’s Largest Single Volcano.

3D images of magma below Mono Craters

A new conceptual model of the magma system below Mono Lake and Mono Craters in eastern California gives scientists a more detailed understanding of volcanic processes at depth and a better model for forecasting volcanic unrest. The accuracy and high resolution of the new three-dimensional images of the magma chambers and volcanic “plumbing” below Mono Basin give scientists a better understanding of their size, shape and where the next eruption might occur.

Studying Tamu Massif

We’re pleased to introduce a series of guest blog posts by Schmidt Ocean Institute’s Research team on their research vessel Falkor. Join us as we catch up with them and follow along on their expedition.

The Falkor is currently on a 36-day research trip. Her destination is Tamu Massif, a massive underwater volcano, located approximately 1500 kilometers (or 932 miles) east of Japan in the Shatsky Rise oceanic plateau. During their journey, researchers will focus on collecting bathymetric and magnetic data that could help clarify how Tamu Massif, possibly the world’s largest single volcano, was formed.

Stunning HD videos show volcanoes erupting … gorgeously

As the Tectonic Plates bend, creak, snap, and rattle in earthquakes, blobs of heated rock rise through them from within and punch through the surface, puffing out vast clouds of rock dust and volatile gas, and pouring out mounds upon mounds of hardening molten rock. Volcanoes may fall under the purview of some other realms of the blogosphere, but a spate of recent videos are just too stunning (and informative!) …

Book Review: The Road

I’ve been on a bit of a post-apocalyptic kick this year. It all started when I got Fallout 3 last Christmas, and once I finished that game I moved on to reading some of the classics of the genre like On the Beach and I am Legend and The Stand. There’s something oddly fascinating about seeing characters face the end of the world, and to me it’s even more interesting …
