Scope of the workshop

On February 2, 2018, Chinese Satellite on Earthquake Study (CSES-1) was launched and started measurements. Not limited to this, progress has been made in the efficient acquisition of various physical parameters globally, from space and ground. The increased observational capacity has brought the multiple detections of earthquake precursory signals and the repeated appearance of the same pattern, which has facilitated the evaluation of precursors concerning statistical significance, repeatability, universality, and effectiveness for forecasting.

The 5th IWEP symposium is jointly organized with the International Symposium on Earthquake Forecast (ISEF) by geomechanics people, many of whom are skeptical about the reality of claimed precursors. For fruitful collaboration between seismology and EM studies, we especially welcome papers claiming the existence of short-term precursors by analyzing existing data statistically and objectively.

In this workshop, while evaluating the statistical performance of pre-earthquake signals, which is also an assessment of the capability of short-term earthquake forecasting at the moment, we further contemplate different physical mechanisms for generation and propagation of pre-earthquake signals. Discussions on earthquake forecast test, integration of multi-parameter observation and international joint research are also included.


  • General discussion on earthquake preparation process and the physics of pre-earthquake signals
  • Statistical analyses of earthquake precursors
  • Theory, modeling, laboratory experiments, computational simulation for generation and propagation of pre-earthquake signals and their connection with seismic cycle
  • Multi-parameter observations, detection, and validation of pre-earthquake signals
  • Integration of multi-parameter observation and related projects and results
  • Cross-disciplinary studies, practical, and technical approaches for better understanding of earthquake preparation processes and their connection with seismicity
  • Presentations on the latest developments in earthquake predictability and prospective testing associated with major earthquakes are welcomed


The workshop will be held at Chiba University (Nishi-Chiba Campus), Chiba, Japan on May 25-27, 2018.
