  • Earthquakes: Caught in the act 
    Braunmiller, Jochen (Macmillan Publishers Limited, 2012-05)
    Faults break under the stress of plate tectonic forces, but the processes immediately preceding rupture are enigmatic. Monitoring of a remote oceanic fault that breaks regularly indicates that rupture is controlled by ...
  • Repeat bathymetric surveys at 1-metre resolution of lava flows erupted at Axial Seamount in April 2011 
    Caress, David W.; Clague, David A.; Paduan, Jennifer B.; Martin, Julie F.; Dreyer, Brian M.; Chadwick, William W., Jr.; Denny, Alden; Kelley, Deborah S. (Nature Publishing Group, 2012-07)
    At sites with frequent submarine volcanic activity, it is difficult to discern between new and pre-existing lava flows. In particular, the distribution of the fissures from which lava erupts, the routes taken by lava flo ...
  • Seismic precursors and magma ascent before the April 2011 eruption at Axial Seamount 
    Dziak, R. P.; Haxel, J. H.; Bohnenstiehl, D. R.; Chadwick, W. W., Jr.; Nooner, S. L.; Fowler, M. J.; Matsumoto, H.; Butterfield, D. A. (Nature Publishing Group, 2012-07)
    Volcanoes at spreading centres on land often exhibit seismicity and ground inflation months to years before an eruption, caused by a gradual influx of magma to the source reservoir¹⁻⁴. Deflation and seismicity can occur ...
