Basalts Turn Carbon into Stone for Permanent Storage

by Kimberly M. S. Cartier 20 March 202022 November 2021

Scientists have shown that mineral carbonation can permanently capture and store carbon quickly enough and safely enough to rise to the challenge of climate change.

Did a Volcanic Eruption in 1783 Change the Climate in Europe?

by David Shultz 17 May 201915 November 2022

A new model of the Laki eruption in Iceland suggests that normal climate variability was to blame for the anomalously warm summer.

More Than 30,000 Earthquakes Trace the Movement of Magma

by Katherine Kornei 14 May 201927 October 2021

Seismometers near Iceland’s Bárðarbunga volcanic system pinpointed thousands of earthquakes in 2014–2015, revealing where molten rock was moving underground before any eruptions occurred.

A New Way of Visualizing Iceland’s Crustal Deformation

by Terri Cook 24 April 20196 October 2021

A novel method of calculating strain rates from GPS data shows the South Iceland Seismic Zone is experiencing rapid deformation, including inflation near the island’s most active volcano.

Volcano in Iceland Is One of the Largest Sources of Volcanic CO2

by Terri Cook 8 November 201815 November 2022

High-precision airborne measurements, in combination with atmospheric modeling, suggest that the Katla subglacial caldera may be one of the planet’s biggest sources of volcanic carbon dioxide.

Magma Flow in a Major Icelandic Eruption

by Sarah Stanley 23 May 20181 November 2021

Mechanical modeling suggests that previous, undetected eruptions released tectonic stress near the ice-covered Bárðarbunga volcano.

A New Model of Drumlin Formation

by Terri Cook 8 February 201811 February 2022

Observations from the surge-type glacier Múlajökull in Iceland underpin new modeling results that suggest the glacier’s drumlins grow during quiet intervals of normal flow between glacial surges.

Volcano’s Toxic Plume Returns as Stealth Hazard

by JoAnna Wendel 20 July 201711 January 2022

During a closely watched eruption, plumes of harmful sulfur dioxide gas morphed into “plumerangs” of sulfuric-acid-rich aerosols that descended on populated parts of Iceland.

A Significantly Hotter Mantle Beneath Iceland

by Terri Cook 18 November 201622 December 2021

Estimates of crystallization temperatures from four eruptions in northern Iceland offer improved constraints on the mantle's temperature beneath this anomalous divergent plate boundary.
