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.

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.
