Merapi Volcano

Book Series: Active Volcanoes of the World

572 pages, Springer, 2023.

This book provides the first comprehensive compilation of cutting-edge research on Merapi volcano on the island of Java, Indonesia, one of the most iconic volcanoes in the world. It integrates results from both the natural (geology, petrology, geochemistry, geophysics, physical volcanology) and social sciences, and provides state-of-the-art information on volcano monitoring, the assessment of volcanic hazards, and risk mitigation measures.

IAVCEI News No. 1, March 2023:

"This comprehensive collection of the latest research summarized
in a single, 18-chapter book has been termed ‘monumental’
(Corado Cimarelli) and a must read for any student of Merapi
volcano (John Pallister)."

Pre-school "Haus für Kinder St. Sebastian" in Dettelbach, Germany, is running the project "Floating Rock" under supervision of Manuela Welter since 2019.

The kids use Youtube, get their questions answered by email and received soundfiles for their audio pen. Some of the content is known by heart by now.

In February 2023 the pre-school received the TOMMI Promotional Award Pre-School fromProf. Dr. Stefan Aufenanger and the Auerbach Foundation.

Teide Volcano

Book Series: Active Volcanoes of the World

279 pages, Springer, 2013.

Teide Volcano has many different meanings ... a 'hell of a job', a navigation point on cloudy days, a challenge beyond imagination, a breakthrough in our understanding of oceanic volcanism that has shaped our way of thinking about volcanoes, and lastly, Teide provides us with a reference point from where to start exploring other oceanic volcanoes in the Canaries and beyond. Here we have compiled the different aspects and the current understanding of this natural wonder.
