More accurate aftershock zones reveal that the rupture areas of megathrust Aleutian–Alaska earthquakes are larger than we thought and partly overlap, in contradiction with the seismic gap hypothesis.

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.
The Failure of Physics-Based Earthquake Forecasting Models
Spatial clustering of aftershocks explains why simple statistical models often outperform complex physics‐based earthquake forecasting models even if the physical mechanisms are correctly modeled.
