Analyses of seismic activities and hazards in Laos: A seismicity approach
Terrestrial, Atmospheric and Oceanic Sciences, 2017 The seismic activities and hazards in People’s Democratic Republic Laos were analyzed using the most up-to-date seismicity data. Both the a- and b-values of the frequency-magnitude distribution model, including the return period of earthquake magnitude in the range of 5.0 - 6.0 Mw, were evaluated spatially in a region that extends 300 km from Laos ...
