EEPAS: Medium-term earthquake forecasting from precursory seismicity.

Request a non-commercial research licence to download and run EEPAS on your own earthquake catalogues.

EEPAS model of precursory seismicity before a mainshock: (a) spatial distribution of precursory events, mainshock, and aftershocks; (b) magnitude versus time; (c) cumulative magnitude anomaly over the precursor period. — **EEPAS precursory seismicity** — spatial, magnitude–time, and cumulative-magnitude views of the precursor signal preceding a mainshock.

01 / About EEPAS

What EEPAS is, and who it's for.

EEPAS — Every Earthquake a Precursor According to Scale — forecasts the rate of future earthquakes from patterns in recent seismicity. This compiled distribution is licensed for non-commercial research and teaching.

Each request records the researcher, institution, and intended use before the binary is released.

Approved applicants receive a personal, expiring link to the hosted binary.

03 / Running EEPAS

From download to first launch.

The hosted release is a Linux x86-64 command-line executable (eepas_dev43g). It runs a forecast from a plain-text control file that points to the earthquake catalogue, search polygon, model parameters, and licence key provided with your approval.

System requirements A 64-bit Linux system with the GNU Fortran runtime (libgfortran5). On Debian or Ubuntu: sudo apt-get install libgfortran5. Use the data files and licence key provided with your approval.

Download into a working directory

Use the personal link in your approval email before it expires.

Make the binary executable

$ chmod +x eepas_dev43g

Prepare the control file and inputs

Place your control file (.eep) together with the catalogue, polygon, parameter, grid, and licence-key files it references in the working directory.

Run a forecast

$ ./eepas_dev43g control.eep

Writes forecast grids (.grd) and logs to the working directory. Keep the executable, download link, and licence key private.
