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 2020 and liquefaction related to volcanic eruptions. These were collated and analyzed from various primary and secondary sources.

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.

本数据库收录了菲律宾的历史液化事故记录。其中包含来自古液化研究的无日期液化记录，1619年至2020年的历史液化记录，以及与火山喷发相关的液化记录。这些记录均来自多种一级和二级资料的综合与分析。

对于地震诱发的液化，历史液化事故记录被归因于引发其的地震事件以及确定的地震源。对于火山喷发引起的液化，事故记录亦被归因于喷发并引发液化的活跃火山。

液化事故记录还根据液化发生的区域、发生液化的地貌单元、描述的液化特征及其发生概率进行了参数化。

所有用于提取液化信息的原始和二手资料亦列于另一份单独的文档中，供其他用户参考。
