A Study of Recent Earthquakes

This work presents concise case studies of notable earthquakes from the recent half-century, assembling observational reports, intensity maps, seismograms, magnetograph and tide-gauge records, and numerous diagrams and photographs. It explains practical methods used to locate epicentres and estimate focal depths, analyzes meizoseismal areas, aftershock distributions, and variable shock characteristics, and documents surface effects such as fault scarps, ground displacement, and structural damage. Each chapter combines field evidence with instrumental data, and a concluding discussion synthesizes methodological lessons and comparative insights for seismological investigation.
