The Earthquake Loss Estimation Routine-ELER methodology and software package were developed within the scope of the European Union's 6th Framework Programme, NERIES project. ELER enables the real-time and/or scenario-based estimation of earthquake ground shaking and portfolio-based probable losses at urban and regional scales in the Euro-Mediterranean region. It basically consists of two analysis modules: Earthquake Ground Shaking Analysis and Earthquake Loss Estimation Analysis. Using information on the earthquake's epicenter, magnitude, and depth, the geographical distribution of ground motion intensity in terms of different parameters (Intensity, PGA, PGV, Sa, etc.) can be calculated. Following the ground shaking calculation, earthquake loss analyses can be performed depending on the available information and data sets. The ELER software; i) Estimates of casualties and injuries based solely on magnitude information and population inventory data, ii) Intensity-based building damage and casualty/injury estimates based on calculated macro-seismic intensity distributions and building and population inventory data, iii) Building damage, casualty/injury, and economic loss estimates based on spectral accelerations and spectral displacements, and building and population inventory data. Furthermore, damage analysis can be performed using different methods with the pipeline module.

The ELER methodology and software package are being regularly updated in line with current scientific and technological developments in the field of earthquake engineering and in light of findings from recent earthquakes. The basic version of the ELER software and the Technical User Manual can be downloaded from the following link:
