Bulletin of Volcanology: *The January 15th 2022 Hunga Tonga-Hunga Haâ??apai eruption - Special Issue* The January 15th 2022 Hunga Tonga-Hunga Haâ??apai (HTHH) eruption unleashed devastating impacts on the Kingdom of Tonga, resulting in damage from ashfall and the associated tsunamis as well as, tragically, four deaths in Tonga and two in Peru. The eruption also exhibited a range of extreme phenomena rarely (or never) previously observed, including an eruption plume up to ~ 55 km high, audible soundwaves across the Pacific region, and meteotsunamis that appeared to â??jumpâ?? over landmasses. After a year of this unique eruption, a topical special issue on various aspects of the event will be highly beneficial to the scientific community. We welcome contributions on any topic concerning the eruption and tsunami, including but not limited to the following themes and subthemes: *1. Eruption and fragmentation processes* - Textural studies of lapilli and ash to determine fragmentation mechanism - Recreating the HTHH event: Experimental and modelling approaches to constrain magma ascent dynamics *2. Petrology and geochemistry* - Glass and mineral chemistry characterising magmatic affinities - Elemental diffusion and timescales of magmatic processes - Melt inclusion studies and volatile quantification *3. Ash: plume, cloud and fallout* - Remote sensing observations - Modelling - Field observations - Big plume, short-lived ash cloud: where did it all go? *4. Volcanogenic tsunamis* - Near-field volcanogenic tsunamis - Global volcanogenic tsunamis (or volcanic meteotsunamis) - Tsunami observations *5. Geomorphological changes to HTHH* - Proximal evolution of the vent area including islands - Wider submarine landform change related to the eruption *6. Impacts and response* - Ash hazard characterisation and associated messaging - Implications for clean-up and re-use of ash - Impacts (including multi-hazard impacts) on soils, crops, coastal fisheries, water resources, built environment - Analysis of social media coverage - Behavioural responses to eruption If you would like to participate, please send a provisional title, abstract and list of authors to either Paul (p.jarvis@xxxxxxxxxx), Carol ( c.stewart1@xxxxxxxxxxxx <c.stewart1@xxxxxxxxxxxx>), Tobi (tobi@xxxxx) or Joali (joa.paredes.marino@xxxxxxxxxxxxxx) by *15 February 2023*. The deadline for manuscript submission is *31 March 2023*. Papers will be published as accepted, and compiled in parallel in the Topical collection and in the main body of the journal. *Guest editors:* Marco Brenna (University of Otago, New Zealand) Tobi Durig (University of Iceland, Iceland) Paul Jarvis (GNS Science, New Zealand) Taaniela Kula (Tonga Geological Services, Kingdom of Tonga) Emily Lane (NIWA, New Zealand) Graham Leonard (GNS Science, New Zealand) Joali Paredes Marino (University of Auckland, New Zealand) Carol Stewart (Massey University, New Zealand) For more detailed information: https://urldefense.com/v3/__https://www.springer.com/journal/445/updates/20421358__;!!IKRxdwAv5BmarQ!YPQru9dhXEZ19JGSAHGFxBbYIYyRAoTV0kDpo1l8cxP_TpERIi7nBZSWGEfFNKY0YnbO8NXW1i6G7Uz8$ <https://urldefense.com/v3/__https://www.springer.com/journal/445/updates/20421358__;!!IKRxdwAv5BmarQ!biwh4hRbxHC5jeIe1QaMjjJUWF_u91A5jiUxRJsdgHk1_LxBwXodKJ8qVlIV6E-xJFOt8uY5fFhVwCr2lrTIOg$> 6-6-6-6-6-6-6-6-6-6-6-6-6 ------------------------------
