Can Meteorite Impacts Disturb a Planet's Magnetic Field?
Such disturbances probably do not occur on our own planet, but evidence for them might still exist elsewhere in the solar system.
Massive Carbon Dioxide Stores Beneath Mammoth Mountain
Gas in rocky pores beneath the surface of California's Mammoth Mountain could fuel dangerous carbon dioxide emissions for the next 28 to 1100 years.
Hawaii’s Swelling Lava Lake Charts a Volcano’s Hidden Plumbing
Geophysicists used unique seismic signatures to track the cyclic rise and fall of lava inside Hawai'i Volcanoes National Park's Overlook crater.
Aftershocks of Old Quakes Still Shake New Madrid Seismic Zone
Geodetic data show that earthquakes in 1450 and 1811–1812 may be responsible for present-day seismic activity in the region.
Wharton Basin Earthquakes: Evidence for a New Plate Boundary?
The largest ever strike-slip earthquake may have occurred on a newly developing boundary between the Indian and Australian plates.
Surface Folds Hint at Magnitude of Slip Along Thrust Faults
The shape of deformed sediments at the surface may allow researchers to estimate the cumulative slip along thrust faults such as the Chelungpu fault in Taiwan.
Dry Minerals in the Lower Mantle
Laboratory-made perovskite helps explain how water is distributed inside the Earth.
Overriding Plate's Properties Affect Subduction
The properties of the plate that does not sink may strongly control subduction zone dynamics.
Rapid Gas Hydrate Forms Pockmarks in Nigeria's Seafloor
The seafloor in deep water regions off the coast of Nigeria is speckled with pockmarks that scientists suggest were mainly made by the rapid formation of gas hydrate.
