The transdimensional Bayesian approach handles GPS data limitations better than existing methods and may assist future seismic hazard assessment studies.
Seismicity and tectonics
The First Systematic Search for Enervated Earthquakes
High quality data from Japan provides answers on where and when “enervated” earthquakes occur.
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.
Imaging Seismic Sources
Waveform‐based location methods are being used to better characterize and understand seismic sources from the laboratory to the global scale.
Geodetic Data Pinpoint Earthquake-Prone Regions of the Himalayas
GPS measurements of the Indian and Eurasian plates reveal four locked segments most likely to produce large earthquakes.
Earthquake Statistics Vary with Fault Size
A theoretical study explores why small earthquake sources can produce quasiperiodic sequences of identical events, whereas earthquakes on large faults are intrinsically more variable.
Monitoring Haiti’s Quakes with Raspberry Shake
A network of “personal seismometers” is intended to complement Haiti’s national seismic network to engage and inform residents about earthquake hazards and preparation.
More Than a Million New Earthquakes Spotted in Archival Data
By reanalyzing seismic records, researchers found a plethora of tiny earthquakes in Southern California that trace new fault structures and reveal how earthquakes are triggered.
How Do Main Shocks Affect Subsequent Earthquakes?
The results of a novel analysis of aftershock size distribution have important implications for more realistically assessing the seismic hazard of earthquake sequences.
Project VoiLA: Volatile Recycling in the Lesser Antilles
Deep water cycle studies have largely focused on subduction of lithosphere formed at fast spreading ridges. However, oceanic plates are more likely to become hydrated as spreading rate decreases.
