Seismic precursors and magma ascent before the April 2011 eruption at Axial Seamount

Creator:

Dziak, R. P., Haxel, J. H., Bohnenstiehl, D. R., Chadwick, W. W., Jr., Nooner, S. L., Fowler, M. J., Matsumoto, H., and Butterfield, D. A.

Abstract:

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 on time scales of hours to days, and result from the injection of magma into adjacent...

Repeat bathymetric surveys at 1-metre resolution of lava flows erupted at Axial Seamount in April 2011

Creator:

Caress, David W., Clague, David A., Paduan, Jennifer B., Martin, Julie F., Dreyer, Brian M., Chadwick, William W., Jr., Denny, Alden, and Kelley, Deborah S.

Abstract:

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 flows and the relationship between the new flows and the pre-existing seafloor bathymetry are often unclear....
