1-1-1-1-1-1-1-1-1-1-1-1-1-1 From: Matteo Roverato <matteo.roverato@xxxxxxxx> Dear Colleagues, We would like to draw your attention to the next *Cities on Volcanoes 12* held in Antigua, *Guatemala, in February 2024.* We kindly invite you to submit your works to our fascinating session, which links Volcanology, Architecture, Materials Science, and Civil Engineering 101 (Theme 1) > *Volcanic Material in Civil Engineering: A Sustainable Approach to Volcano-Driven Development* Volcanoes have shaped our planetâ??s history and continue to influence our environment nowadays. Despite their destructive capacity, volcanoes can be also a source of assets and benefits for the sustainable development of our society. Historically, humans have learned how to take advantage of volcanic products, one of them, undoubtedly, is the use of volcanic rocks for building constructions. Case studies of successful construction projects in different parts of the world, as well as discussions on the challenges and opportunities of applying volcanic material in different geographical and cultural contexts, have been presented in several scientific contributions as well as, in architecture and engineering journals. In this session, we will explore the exploitation and the use of volcanic material in civil works to take advantage of the resources that volcanoes can provide. We will discuss historical technics and the advances in research and construction practices using volcanic material. In addition, we will highlight how the use of volcanic material in civil works can boost development in communities near volcanoes, including job creation and infrastructure improvement. This session encourages contributions from different and complementary disciplines including volcanology, civil engineering, and architecture. We are also eager to include a perspective from the local community on how the use of volcanic material in civil works has had a positive impact on their development. Presentations will include a discussion on the ancient (in archeological and historical time) and current state of the use of volcanic material in civil works, examples of successful projects, and discussion on the challenges and opportunities in the use of this natural resource as a sustainable solution for development, and how it can be used effectively to improve the lives of communities near volcanoes.
