Fission track dating core samples from the Gulf of Alaska demonstrates that offshore sediments can be used to reconstruct a mountain range's changing exhumation patterns.Read More »Hydrology, Cryosphere & Earth Surface
A "big data" analysis of nearly 1 million river junctions in the contiguous United States shows that branching angles in dendritic drainages vary systematically between humid and arid regions.Read More »Geology & Geophysics
A decade of continuous GPS measurements in South America indicates that enhanced strain accumulation following a great earthquake can initiate failure along adjacent fault segments.Read More »
Reordering of mineral crystal lattice structures during laboratory heating may explain the frequent need to reject results of experiments that estimate the intensity of Earth's past magnetic fields.Read More »
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 »
