Dataset: Historical liquefaction occurrences in the Philippines

This database contains historical liquefaction accounts of the Philippines. It includes undated liquefaction records from paleoliquefaction studies, historical liquefaction from 1619 to 2023 and liquefaction related to volcanic eruptions. These were collated and analyzed from various primary and secondary sources. To know more about the development of this database, please refer to the paper by Buhay et al. (2024) about the "Development of a database of historical liquefaction occurrences in the Philippines" https://doi.org/10.1016/j.earscirev.2024.104733

For earthquake-induced liquefaction, the historical liquefaction accounts were attributed to the earthquake event that caused them, as well as the identified earthquake generator. For liquefaction caused by volcanic eruptions, the accounts were also attributed to the active volcanoes that erupted and caused liquefaction.

The liquefaction accounts are also parameterized based on the area where they occurred, the geomorphic unit that liquefied, liquefaction features described, and their probability of occurrence.

All primary and secondary sources where the liquefaction information were derived are also listed on a separate document for reference of other users.
