Earthquake attenuation models and its responses to earth zone dam in upper northern part of Thailand

© Int. J. of GEOMATE. The upper northern part of Thailand is mountainous area which classified as moderate risk by earthquake. This study was focused on the earthquake attenuation model of Abrahamson and Silva (2008). Exciting quake source from the Chiang Rai 2014 earthquake was recorded at earth zo...
