THE RELEVANT THEMATIC AREA AND RESEARCH QUESTIONS ARE RELATED TO LAND SURFACE CHANGE AND ASSOCIATED NATURAL HAZARDS. THE FIRST TWO RESEARCH QUESTIONS ARE PARTICULARLY RELEVANT:1. PREDICTION: HOW CAN KNOWLEDGE OF THE EARTH'S SURFACE CHANGE BE USED TO PREDICT AND MITIGATE NATURAL HAZARDS?2. VARIABILITY: HOW IS THE EARTH'S SURFACE BEING TRANSFORMED BY NATURALLY OCCURRING TECTONIC AND CLIMATIC PROCESSES?WE HAVE DEVELOPED THE CAPABILITY TO MODEL EARTHQUAKES GRAVITY AND SEA LEVEL USING THE CODE BASE VIRTUAL QUAKE: HTTPS://GEODYNAMICS.ORG/CIG/SOFTWARE/VQ/ AT THE PRESENT TIME WE ARE EXTENDING THIS TECHNOLOGY TO THE DYNAMICS OF TSUNAMIS USING THE SIMPLE CELLULAR AUTOMATON APPROACH EMBODIED BY THE TSUNAMI SQUARES METHOD (XIAO ET AL. 2015). THIS APPROACH WILL ALLOW US TO COMBINE OUR PREVIOUS STUDIES OF EARTHQUAKE PHYSICS GRAVITY CHANGE AND FORECASTING IN SUPPORT OF THE TSUNAMI EARLY WARNING TECHNOLOGY CURRENTLYBEING PURSUED BY NASA.WHEREAS MUCH OF OUR WORK IN THE PAST WAS FOCUSED ON STRIKE SLIP FAULTS IN CALIFORNIA THIS PROPOSAL WILL EXTEND THESE MODELS TO GLOBAL APPLICATIONS PARTICULARLY EMPHASIZING SUBDUCTION ZONES. THE PROPOSED WORK WILL BE IN SUPPORT OF NASA OBJECTIVES TO DEVELOP A VARIETY OF PREDICTIVE CAPABILITIES AND EARLY WARNING TECHNOLOGIES FOR MAJOR EARTHQUAKES BOTH THROUGH EXTENSIVE DATA ANALYSIS AND MODELING STUDIES EXTENDING METHODS DEVELOPED UNDER PREVIOUSNASA FUNDING SUPPORT. OUR WORK WILL ENTAIL FURTHER DEVELOPMENT OF THE CODE VIRTUAL QUAKE. WE HAVE RECENTLY PUBLISHED METHODS FOR OPTIMIZING USE OF THE CODE FOR INTERPRETATION OF UAVSAR OVER LAND MASSES AND GRAVITY AND SEA LEVEL DATA IN OCEANIC REGIMES.
