Forecasting earthquakes and earthquake risk

International Journal of Forecasting, 1995
This paper reviews issues, models, and methodologies arising out of the problems of predicting earthquakes and forecasting earthquake risk. The emphasis is on statistical methods which attempt to quantify the probability of an earthquake occurring within specified time, space, and magnitude windows.

Bayesian Forecast Evaluation and Ensemble Earthquake Forecasting

Bulletin of the Seismological Society of America, 2012
The assessment of earthquake forecast models for practical purposes requires more than simply checking model consistency in a statistical framework. One also needs to understand how to construct the best model for specific forecasting applications. We describe a Bayesian approach to evaluating earthquake forecasting models, and we consider related ...

Comparison between alarm-based and probability-based earthquake forecasting methods [PDF]

Geophysical Journal International, 2023
In a recent work, we applied the every earthquake a precursor according to scale (EEPAS) probabilistic model to the pseudo-prospective forecasting of shallow earthquakes with magnitude M 5.0 in the Italian region.

Editorial: Pre-earthquake observations and methods for earthquake forecasting and seismic hazard reduction

Frontiers in Earth Science, 2023
Understanding the governing principles, which include long-term tectonic loading, sluggish nucleation, and rapid fracture propagation, enables estimation of the stress level and change during geophysical observations in seismically active locations ...

Forecasting Southern California Earthquakes

Science, 1982
Since 1978 and 1979, California has had a significantly higher frequency of moderate to large earthquakes than in the preceding 25 years. In the past such periods have also been associated with major destructive earthquakes, of magnitude 7 or greater, and the annual probability of occurrence of such an event is now 13 percent in California.

Forecasting Earthquakes: The RELM Test

Computing in Science & Engineering, 2012
Earthquakes don't have precursors that can be reliably used for earthquake prediction. However, distributions of earthquakes (seismicity) can be used to forecast an earthquake hazard. These distributions in space, time, and magnitude can be studied in a variety of ways.

Operational Earthquake Forecasting Can Enhance Earthquake Preparedness

Seismological Research Letters, 2014
We cannot yet predict large earthquakes in the short term with much reliability and skill, but the strong clustering exhibited in seismic sequences tells us that earthquake probabilities are not constant in time; they generally rise and fall over periods of days to years in correlation with nearby seismic activity.

Worldwide earthquake forecasts

Stochastic Environmental Research and Risk Assessment, 2016
We review global earthquake forecast as it was developed by our UCLA Group since 1970s. We discuss the new results on earthquake magnitude/moment distribution, especially the determination of maximum/corner moment magnitude. Recent successes of global geodetic surveys allow us to construct a high resolution map of the Earth surface displacement and ...

Speculations on Earthquake Forecasting

Seismological Research Letters, 2003
A new understanding of the way fluid-saturated microcracked rocks deform suggests that networks of stress-monitoring sites could lead to earthquake forecasting analogous to the way networks of meteorological stations allow weather forecasting and prediction of storms.
