Jonathan Dioso Tan is a Filipino politician and businessman who served as mayor of Pandan, Antique from 2010 to 2019. He was appointed on April 28, 2023 as the Chairman and Administrator of the Subic Bay Metropolitan Authority (SBMA).

Accomplishments One of his major accomplishments was making Pandan a recipient of Pantawid Pamilyang Pilipino Program or 4Ps, an anti-poverty project of DSWD. Mayor Tan's initiative to source out funds from Senators paved the way for more development projects in the municipality. His trademark, JDT, aside from it as an abbreviation of his name, stands for Jobs, Development and Tourism. He managed to enhance the tourism industry in the town as Pandan was included in the 77 Tourism Development areas identified by DOT. It benefited not just the town itself, but also other Eco-tourism destinations in Northern Antique.

Among the others rescued were actresses Bianca Manalo and Ehra Madrigal, as well as Madrigal’s husband. One other occupant died due to stroke and drowning.
