1. During the semester Introductions Basics of earthquakes History and Recording Damaging Earthquakes and understanding seismic exposure Undertake loss assessment Seismic analysis; and design and detailing (RCC and Masonry)

2. Body wave magnitude (M b ) Fastest way of recording earthquake magnitude Used in recording Long distance earthquake Records amplitude of the ‘P’ wave (Compression Wave): Wave Velocity: 5 - 8 km/s Mb = log(A/T) + σ(D,h) – A: Maximum Amplitude – T: Time, σ(D,h)= Callibration for Depth and Height factors

3. Some points on History, Recording and Monitoring of earthquakes Note Scales (Magnitude and Intensity) are continuously evolving and changing Most popular Magnitude scale is Moment Magnitude (M w ) scale Similar scales exist. Such as Surface waves Cautiously use the source internet Quote website name or person/agency for the work done
