Autor: Thomas J. Jones, Frances Beckett, Benjamin Bernard, Eric C. P. Breard, Fabio Dioguardi, Josef Dufek, Samantha Engwell, Julia Eychenne

Publikováno v: Frontiers in Earth Science, Vol 11 (2023)

Pyroclastic density currents (PDCs) are hazardous and destructive phenomena that pose a significant threat to communities living in the proximity of active volcanoes. PDCs are ground-hugging density currents comprised of high temperature mixtures of

Downward-propagating eruption following vent unloading implies no direct magmatic trigger for the 2018 lateral collapse of Anak Krakatau

Autor: Kyra Cutler, Sebastian Watt, Mike Cassidy, Amber Madden-Nadeau, Samantha Engwell, Mirzam Abdurrachman, Muhammad Nurshal, David Tappin, Steven Carey, Alessandro Novellino, Catherine Hayer, James Hunt, Simon Day, Stephan Grilli, Idham Kurniawan, Nugraha Kartadinata

The lateral collapse of Anak Krakatau volcano, Indonesia, in December 2018 highlighted the potentially devastating impacts of volcanic edifice instability. Nonetheless, the trigger for the Anak Krakatau collapse remains obscure. The volcano had been

Modeling of the Dec. 22nd 2018 Anak Krakatau volcano lateral collapse and tsunami based on recent field surveys: Comparison with observed tsunami impact

Autor: Sebastian F. L. Watt, Mirzam Abdurrachman, David R. Tappin, James E. Hunt, Alessandro Novellino, Cheng Zhang, Stephan T. Grilli, Samantha Engwell, Michael Cassidy, Muhammad Edo Marshal Nurshal, James T. Kirby, Simon Day, Annette R. Grilli, Amber Madden-Nadeau

The Dec. 22, 2018 lateral collapse of the Anak Krakatau (AK) volcano in the Sunda Straits of Indonesia discharged volcaniclastic material into the 250 m deep caldera southwest of the volcano and generated a large tsunami, causing runups of up to 85 m

The magmatic and eruptive evolution of the 1883 caldera-forming eruption of Krakatau: integrating field- to crystal-scale observations

Autor: Michael Cassidy, Sebastian F. L. Watt, Muhammad Edo Marshal Nurshal, David M. Pyle, David R. Tappin, Tamsin A. Mather, Samantha Engwell, Mirzam Abdurrachman, Amber Madden-Nadeau, Taufik Ismail

Explosive, caldera-forming eruptions are exceptional and hazardous volcanic phenomena. The 1883 eruption of Krakatau is the largest such event for which there are detailed contemporary written accounts, allowing information on the eruptive progressio
