  • Use of geophysical methods for input into fault studies
    
• Seismic hazard assessment
  
  • Deterministic seismic hazard assessment
    
  • Probabilistic seismic hazard assessment
    
  • Linear and nonlinear ground response analysis
    
  • Micro-zonation studies
    
• Soil liquefaction studies utilizing GIS routines
  
  • Lateral spreading
    
  • Liquefaction-induced ground settlement
    
  • Liquefaction mitigation (design of deep soil mixing, stone columns, compaction grouting, deep dynamic compaction)
    
  • Effects of soil liquefaction and lateral spreading- ground response, pile foundations, pipelines, and waterfront structures
    
• Earthquake-induced landslides/slope instability evaluations
  
• Seismic soil-structure interaction studies for onshore, near shore, and offshore structures
