Analysis of the change in the stratovolcano's tilt just prior to the explosion suggests that the cracking of a previously intact fluid barrier caused the country's deadliest eruption since 1926.Read More »
Data from California's Whipple Mountains suggest this complex was formed by a succession of steep normal faults, challenging the paradigm that detachments are different types of faults.Read More »Geochemistry, Mineralogy, Volcanology
Detailed analysis of cores drilled through New Zealand's most dangerous on-land fault indicates that its permeability and strength are altered by mineral precipitation between seismic events.Read More »
Results of the first geographically based estimates of river nutrient supply indicate that 75% of dissolved nitrogen and 80% of phosphorus reach the open ocean.Read More »Geochemistry, Mineralogy, Volcanology
A new model tracks boron and other tracers in fluids expelled from subducting slabs to help identify the fluids' source regions and migration routes.Read More »Geochemistry, Mineralogy, Volcanology
A detailed study of layered igneous material at California's Fisher Lake offers a novel approach to identifying the pathways and timescales of individual magma pulses in volcanic arcs.Read More »Hydrology, Cryosphere & Earth Surface
An uninterrupted 24-year altimetry record of Amundsen Sea Embayment glaciers indicates the initiation and pace of thinning have been inconsistent across the region.Read More »History of Geophysics
A global review of earthquake rupture parameters reveals that deep earthquakes have larger fracture energies and may have different rupture mechanisms than shallower seismic events.Read More »Geochemistry, Mineralogy, Volcanology
Records from drill holes in the eastern equatorial Pacific indicate that Earth's orbital eccentricity played an important role in controlling climate as the planet warmed.Read More »
