b-values#

analysis.estimate_b

Returns the b-value of the Gutenberg-Richter (GR) law.

analysis.shi_bolt_confidence

Returns the Shi and Bolt (1982) confidence limit of the b-value or beta.

Estimators#

analysis.ClassicBValueEstimator

Estimator to calculate the b-value and other parameters of the Gutenberg-Richter (GR) law.

analysis.BPositiveBValueEstimator

Estimator to calculate the b-value and other parameters using only the earthquakes with magnitudes \(m_i \ge m_{i-1} + dmc\).

analysis.BMorePositiveBValueEstimator

Estimator to calculate the b-value and other parameters of the Gutenberg-Richter (GR) law using earthquake pairs for which the latter is the first one that is larger than the former by some margin, \(m_j \ge m_{i} + dmc\).

analysis.UtsuBValueEstimator

Estimator to calculate the b-value and other parameters of the Gutenberg-Richter (GR) law using the Utsu method.

B-Significant#

analysis.b_significant_1D

Estimates the significance of variation of b-values (or a-values) along a one-dimensional series of events.

Other#

analysis.make_more_incomplete

Returns filtered magnitudes and times.

analysis.beta_to_b_value

Converts the beta value to the b-value of the Gutenberg-Richter law.

analysis.b_value_to_beta

Converts the b-value to the beta value of the exponential distribution.
