| Session Description | Paleoseismology has evolved in several decades. This approach has helped the scientific community to identify the historical and pre-historical earthquakes signature preserved in geological records, having manifestations either on the earth’s surface or in the sediment successions. This has been commonly adopted technique in many Asian countries, which have wealthy ancient culture and have experienced severe earthquake disasters. Some countries have well preserved documents on such disasters in historic time. However, still there are many countries that are under the threat of earthquake hazards but do not have enough data/documents. Therefore, historical earthquake studies such as collection of historical earthquake data from archives, establishment of seismic intensity scales, compilation of historical earthquake catalogues have been done in Asian countries for many years. Along with this, geological methods such as trenching surveys across active faults, identifications of liquefaction features, and searching for evidences of such catastrophic events at archaeological sites or tsunami deposits in coastal environments have been used for identifying and characterizing paleoearthquakes. These studies not only provide information on the behavior of fault segments, pattern of surface deformation, recurrence interval but also are useful for long- and mid-term earthquake forecast. |
