1991Geotechnical Properties of Redisposited Lahar Derived from 1991 Mt. Pinatubo EruptionArticleBaseline data was obtained through a subsurface investigation program consisting of laboratory tests and field exploration on 15 areas located in Zambales, Pampanga and Tarlac. Recommendations for the analysis and design of shallow foundations, slopes and retaining structures were formulated. Correlations, which can be used to obtain textural and shear strength parameters from field tests, were also developed. Results of the subsurface investigation also reveal a high potential for liquefaction in most of the sites considered in the project. Finally, a hyperbolic constitutive model is proposed to describe the stress-strain behavior of lahar. Comparison of laboratory test results with those predicted by the proposal model show good agreement.

Assessment of the Liquefaction Potential of Metropolitan Manila AreaReportThis project came about through the involvement of the office in a Training Programme on Earthquake Engineering and Disaster Management for Establishing Building Administration System in the Philippines. Since the staff involved has already transferred to another government agency, the work has to be reassessed.
