ABSTRACT: EARTHQUAKES AFFECT THE BROADEST REGIONS COMPARED TO OTHER NATURAL HAZARDS AND ARE TREMENDOUSLY DESTRUCTIVE TO BOTH LIFE AND PROPERTY. THE SIZE OF AN EARTHQUAKE IS DENOTED BY ITS MOMENT MAGNITUDE (MW) WHICH IS A MEASURE OF THE ENERGY RELEASED AND THUS A PROXY FOR HOW DESTRUCTIVE THE EARTHQUAKE IS. MW IS DIRECTLY RELATED TO THE AREA OF THE FAULT PLANE THAT RUPTURED SUCH THAT MW A SUA WHERE S IS THE SHEAR MODULUS U IS THE AVERAGE DISPLACEMENT AND A IS THE AREA OF THE FAULT PLANE THAT RUPTURED. IN THRUST FAULT SYSTEMS RAMP LOCATIONS ARE CRUCIAL TO HAZARDS ASSESSMENTS; BOTH BECAUSE OF THEIR CONTROL ON THE AVAILABLE FAULT PLANE AND THE FOCUSED UPLIFT ABOVE THEM. THE MAXIMUM POSSIBLE AREA OF RUPTURE IS LIMITED BY THE LOCATION OF THRUST RAMPS AND THE EXTENT OF THE FLAT IN BETWEEN. RECENT STUDIES HAVE BROUGHT TO ATTENTION THAT PREVIOUS ESTIMATES OF THE POSSIBLE EARTHQUAKE MAGNITUDES IN THE EASTERN CORDILLERA CENTRAL ANDES WERE LIKELY UNDERESTIMATING THE AREA OF RUPTURE AND THAT THE NORTHERN BOLIVIA IS MORE LIKELY TO RUPTURE THAN SOUTHERN. THIS RESEARCH PROPOSES TO IDENTIFY THE LATERAL VARIATION IN AREA AVAILABLE TO RUPTURE IN SOUTHERN PERU AND NORTHERN BOLIVIA TO QUANTIFY THE EARTHQUAKE HAZARDS THROUGH ASSIMILATION OF SURFACE- SATELLITE- AND LABORATORY-BASED DATA IN COMBINATION WITH STRUCTURAL THERMAL AND GEOMORPHOLOGIC MODELLING.
