The IASPEI/IAGA Heat Flow Autumn 2025 was a series of events during the IAGA/IASPEI Joint Scientific Meeting 2025 in Lisbon, Portugal (31 Aug - 05 September 2025) promoting research on terrestrial heat flow. The following activities took place on Monday and Tuesday during the meeting week:

Monday the 1st of September

• J10a - The influence of the thermal state of the lithosphere on the tectonic processes: insights from heat-flow data and implications for geothermal resources, 4-6 pm (science session J10a in room A.2.16/18)
  Chair: Maria Rosa Duque
  Speaker: Sven Fuchs, Rosa Maria Prol-Ledesma, Mafalda Miranda, Labani Ray, Raquel Negrete Aranda

• X - Open IHFC workshop on data standardization, 6:30-8 pm (workshop in room C.0.22)
  Chair: Ben Norden (working group Borehole Temperature and Paleoclimate)
  The IHFC was meeting to discuss the progress and next steps in the standardization of the borehole temperature and rock property database of the IHFC.

Tuesday the 2nd of September

• J10b - The influence of the thermal state of the lithosphere on the tectonic processes: insights from heat-flow data and implications for geothermal resources, 8:30-10:00am (Business Meeting IHFC in room A.2.16/18)
  Chair: Ivone Jiménez-Munt,
  Speaker: Magdalena Scheck-Wenderoth, Kevin Furlong, Yaqi Wang, Shoichi Yoshioka, Linda Bonorino

• X - Open heatflow.world stakeholder meeting, 1-2 pm (IHFC workshop in room C.0.22)
  Chair: Sven Fuchs (working group: Global Heat Flow Database)
  The IHFC and the team of the World Heat Flow Portal Project held its stakeholder meeting on Tuesday. The project aims to consolidate and improve the research data infrastructure for the IHFC Global Heat Flow Database that offers a one-stop shop for comprehensive information on heat-flow related data, publications, projects, and researchers.

• X - Mid-term IHFC business meeting, 6-8 pm (Business Meeting in room A.2.11)
  Chair: Raquel Negrete Aranda The minutes can be found here.

• IHFC dinner, 8-10 pm (Location: tba)
  The dinner was self-paid and open.
