COMET GEM

COMET-GEM Central Asia Seismic Hazard Project

Overview
Anchor 1

Background

Since 2021, COMET and GEM have partnered to integrate the latest advancements in earthquake science into seismic hazard and risk modeling. The first phase of the collaboration (2020–2022) focused on building essential datasets, including an active fault database, a homogenized earthquake catalog, GNSS data, and a preliminary seismic hazard model for Central Asia. The ongoing second phase (2023–2025), supported by the Natural Environment Research Council (NERC), UK, expands on these efforts by incorporating time-dependent hazard modeling, earthquake clustering analysis, and geodetic data processing. By bridging scientific research with practical applications, the collaboration ensures that hazard models remain at the forefront of earthquake risk assessment, strengthening disaster preparedness efforts in Central Asia and beyond.


Duration: Phase 1: 2021 -2023, Phase 2: 2023 - 2025

Overall Objective

The COMET-GEM collaboration aims to develop an advanced, publicly accessible seismic hazard and risk model for Central Asia, integrating cutting-edge scientific methods such as satellite geodesy, palaeoseismology, and geodetic data analysis. The goal is to provide local communities, researchers, and policymakers with robust hazard and risk assessments to inform disaster risk reduction strategies and enhance preparedness for future seismic events.


Specific Objectives / Expected Outputs

1. Enhancing Seismic Hazard Models

  • Refining fault databases, earthquake catalogs, and strain rate fields to improve hazard predictions.

  • Incorporating time-dependent earthquake occurrence models and earthquake clustering analysis to improve forecasting.


2. Integrating Advanced Scientific Techniques

  • Utilizing InSAR-based deformation data and GNSS datasets to quantify seismic strain accumulation across Central Asia.

  • Developing high-resolution geodetic velocity fields for improved hazard modeling.


3. Supporting Disaster Risk Reduction

  • Integrating hazard models into seismic risk assessments to estimate economic and human losses.

  • Engaging local communities and stakeholders in seismic hazard model development.


4. Collaborative Research and Capacity Building

  • Hosting workshops and training sessions to enhance regional expertise in seismic hazard assessment.

  • Supporting research collaborations in Central Asia, the South Caucasus, and beyond.
