Earthquake Seismology Lars Ottemöller University of Bergen, Norway
2
Earthquakes What are they? Where do they occur? When do they destroy? What do we learn from them? How are they measured?
3
Seismology Study of : Earthquakes Elastic wave propagation Results are: Images and Dynamics of Earth interior Basic understanding of the earthquake process Applications: Academic, Seismic hazard, hydrocarbon production, nuclear explosion monitoring,...
