Module 1 :

Module 1: Fundamentals of Earthquake and Volcano Deformation - Introduction to crustal deformation: stress, strain, and rheology of Earth's lithosphere Fundamentals of seismology: earthquake genesis, fault mechanics, and seismic waves Volcano deformation mechanisms: magmatic pressure, dike propagation, and caldera collapse Monitoring techniques: GPS/GNSS, InSAR, and tiltmeters for crustal deformation studies.

Module 2: Earthquake Deformation and Seismic Hazards - Tectonic and non-tectonic sources of earthquakes Fault rupture mechanics, afterslip, and post-seismic deformation Seismic hazard assessment: liquefaction, ground shaking, and induced seismicity Case studies of major earthquakes and associated crustal deformation.

Module 3: Volcanic Deformation and Eruption Dynamics - Magma chamber dynamics and pressure-induced deformation Ground deformation as an eruption precursor: uplift, subsidence, and inflation-deflation cycles Role of external factors: tidal forces, hydrological effects, and climate interactions on volcanic activity Monitoring volcano deformation: real-time data interpretation and early warning systems.

Module 4: Crustal Deformation Modeling and Prediction - Analytical and numerical modeling of fault and volcano deformation Coulomb stress transfer and its implications for seismic and volcanic activity Integrating geodetic and seismic data for hazard forecasting Case studies: deformation modeling of recent major earthquakes and volcanic eruptions.

Module 5: Implications for Hazard Mitigation and Risk Assessment - Deformation-driven hazard assessment and early warning systems Infrastructure resilience to earthquake and volcano-related ground movements Role of remote sensing and geophysical techniques in risk evaluation Case studies: earthquakes and volcanic crises that reshaped hazard assessment strategies.
