- Janine and Alison
Conferences mean many things. We get to see our co-blogger in person, go on field trips where we learn about new volcanoes from the people who have studied them, attend workshops and panels, make new friends, and race from talk to poster sessions to take in as much volcano science as we can.
The International Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI) 2017 conference is being held in Portland Oregon this August. The theme is 'Fostering Integrative Studies of Volcanism'. The conference will be attended by more than 1,000 volcanologists from around the world and many will be sharing their experience on Twitter using the hashtag #IAVCEI2017. This year we are both going on field trips and presenting some of our recent research at this conference so there will be a lot of conference to share.
Janine will be presenting her work on the Shiveluch dome collapse events and block-and-ash flow (BAF) deposits, and how the link together. These BAFs are some of the largest historical events on Earth! Shiveluch has been producing BAFs since 2001 (in the current eruption cycle), after a Mount St. Helens-style flank collapse (minus the lateral blast) removed a portion of the volcano in 1964. This talk will be discussing the distributions of the dome collapse events (it's a big dome!) and the deposits that result from them. This gives insight into how deposits are distributed through a long-lived dome-building eruption.
Presentation time: Friday 2:30 - 2:45
Session: PE52A: III.9 Understanding pyroclastic density currents through analysis of their deposits II, 2:00 PM - 4:00 PM
Alison will be giving both a talk and a poster. Monday morning Alison is giving an invited talk in a session called "Volcanism and Magmatism under Water or Ice.” The presentation will focus on Askja volcano, in central Iceland, which is just north of the Vatnajokull ice sheet (and just north of the Holuhraun eruption site from 2014-2015). Askja is of interest because it grew during the last glacial period when the ice sheet was much larger and produced a large volume of explosive and effusive deposits that interacted with the the ice. We can learn about the mechanisms of these glaciovolcanic eruptions and the thickness / location of the ice by mapping these deposits.
Session: ME11A: 11.6 Volcanism and magmatism under water or ice I, 11:00 AM-1:00 PM
Alison is also giving a poster that relates her experimental work and natural volcanic deposits. The transport and deposition of material out of a crater by discrete explosions produced by magma and water interacting underground results in distinctive depositional textures and sequences. The poster looks at two type examples and then expands the observations to previously published deposit descriptions.
Room: Exhibit Hall A
Session VH43B: V.4 Just add water: hazards variation in lava flows, steam-driving and hydromagmatic explosive eruptions, Posters, 4:00 PM -6:00 PM
Also Alison's masters student Cody Nichols will be giving a talk on his work looking at the relationship between the shape of maar craters (produced by those subsurface explosions mentioned above) and the regional stress regime.
Presentation time: Monday 2:45-3:00 pm
Session: PE12A: III.5 Processes leading to monogenetic volcanism II, 2:30 PM-4:30 PM
We will both do our best to tweet some of the conference, including our field trips to Mount St. Helen's, Mount Hood, the Sand Mountain volcanic field, Mount Bachelor, and Crater Lake. Conferences are a combination of a lot of work, not enough time, and awesome.
