Slipping and Locking in Earth’s Earthquake Factories
Geodetic observations collected during back-to-back decadal research campaigns have revealed crucial new insights into the start–stop and slow-motion behavior of subduction zones.
A New Robust Estimator of Earthquake Magnitude Distribution
The b-value, which describes the fraction of large versus small earthquakes, is less sensitive to transient changes in detection threshold and may improve the detection of precursory changes.
Discerning Structure and Seismic Hazards in the Sikkim Himalayas
A dense seismic network in operation since 2019 will provide new insights into the tectonics of seismically active Himalayan regions.
A New Understanding of the Mid-Atlantic Ridge and Plate Tectonics
The first seismic data obtained directly from the Mid-Atlantic Ridge suggest that upwelling may contribute to seafloor spreading.
Hunting the Source of Deccan Traps Volcanism Using Seismic Waves
Seismic velocity patterns beneath the Deccan Traps region in western India reveal its volcanic history.
A New Picture of Seismogenesis on the Philippine Fault
Long-time series of satellite observation reveal that the creeping segment of the Philippine Fault is also capable of producing strong earthquakes, and show where these earthquakes might occur.
Students Monitor Campus Noise in Seismic Silence
Researchers are engaging their students with low-cost seismology research to monitor local noise on campus.
Geologists to Shed Light on the Mantle with 3D Model
The model, which will incorporate 227 million surface wave measurements, could help with everything from earthquake characterization to neutrino geosciences.
A Pandemic Pivot in Earth Science Outreach and Education
For some educators, restrictions imposed by COVID-19 created space for innovation and affirmed the value of online tools and learning environments for increasing access to and engagement with science.
