Geotalk is a regular feature highlighting early career researchers and their work. In this interview we speak to Jackie Kendrick, a volcanologist at the University of Liverpool, and winner of the 2016 GMPV Outstanding Young Scientist Award. The occasion will be marked during the upcoming General Assembly, where you’ll be able to listen to Jackie speak in session GMPV 1.1 on the topic of friction in volcanic environments. First, could you introduce yourself and tell us a little more about your [...]

Increase in volcanic eruptions at the end of the ice age caused by melting ice caps and glacial erosion 

AGU Meetings [2016-02-02 17:16:08]  recommend  recommend this post  (166 visits) info

 GB
The combination of erosion and melting ice caps led to a massive increase in volcanic activity at the end of the last ice age, according to new research. As the climate warmed, the ice caps melted, decreasing the pressure on the Earth’s mantle, leading to an increase in both magma production and volcanic eruptions. The researchers, led by the University of Cambridge, have found that erosion also played a major role in the process, and may have contributed to an increase in atmospheric carbon [...]

In this guest post,  Sam Illingworth, regular contributor to GeoLog on all things science communication and education, discusses whether it is the responsibility of all geoscientists to communicate their science and research and challenges you to make some time to get involved in public engagement in 2016. As researchers it is very easy to get caught up in the whirlwind of our scientific endeavours that we forget about the impact of what it is that we are doing. Geoscience is not done in [...]

We are underway for the first of two voyages on The World. Beginning in Ushuaia Argentina (the world's southernmost city) we sailed for 38 hours until we spotted land in Antarctica. This was one of the fastest crossings for me ever - The World's twin screws push us through the sea at an amazing 18 knots. The weather was as good as it gets crossing the Drake Passage and about as bad as it gets in the Antarctic summer once we arrived. See the photo's below.Mt. Oliveira and the city of Ushuaia on [...]

In the digital era of instant communication, breaking news of volcanic eruptions usually arrive image-first. This year, spectacular eruptions of Calbuco (Chile), Fuego (Guatemala) and Etna (Italy) have all made it into the end-of-year ‘top tens‘, in glorious multicolour detail. But when was the first photograph taken that captured one instant during a volcanic eruption? And which was the first such photograph to make it into print? One example may be the April 1872 eruption of [...]

Volcanic eruption not just stated the lives of humans, but additionally transformed the face area of character. Earth takes 100s of many years to get over the results of volcanic eruptions.

From 14-18th March, disaster professionals, politicians and other stakeholders will be gathering in Sendai (Japan) at the UN World Conference on Disaster Risk Reduction (WCDRR). The aim of the meeting will be to agree upon the final text to replace the Hyogo Framework for Action, the UN guidelines for action on disaster risk reduction and strengthening resilience.

There is a story I tell on the first day of almost every class I teach. It's about a place filled with the evidence of one of the great explosions in Earth history, near Mammoth Lakes in the eastern Sierra Nevada. The students in the picture above are standing on the edge of a gorge that exposes some aspects of the explosion, but no one place reveals the full magnitude of what happened here.

How ‘Natural’ is a ‘Natural Disaster’?

‘Natural disasters’ is a phrase widely used by the geoscience community but how accurate is it? Given the human and societal factors that create a disaster, it has been highlighted that there is no such thing as a natural disaster. Is this simply a convenient phrase that recognises the contribution of natural processes (e.g., earthquakes), are we being sloppy with our language, or are we reinforcing the (incorrect) opinion that disasters are inevitable events, so called [...]

So I am already skeptical about this, but there are news reports emerging of a 'new' volcano in India, in the province of Himachal Pradesh, an area in Northern India near the border to Indian controlled Kashmir. The area does not have a previous record of eruption, and unverified news reports such as this should be treated with a HIGH amount of skepticism. As this article reports:"Flames and a hot liquid stream were seen spewing out of a hill 100 m from Gadiyada village. The village is [...]

Mt St Helens Is Inflating Again

It appears that Mt St Helens is experiencing gradual re-inflation of its magma chamber, leading some to feel concern that the volcano will erupt again in the near future. St Helens last eruptive period ended in 2008 with a dome building event, which consisted of slow extrusion of a central lava dome, and occasional ash fall due to collapse of the dome. The current inflation period does not indicate an eruption is imminent, although it does significantly raise that possibility.It is common for [...]
