Three core activities of the workshop will be: (1) gas composition measurements using direct sampling and sensor techniques, (2) plume measurements using remote sensing techniques, and (3) soil degassing surveillance.<\/p>\n\n\n\n<p>The workshop will include two days of scientific meetings followed by three days of field observations. The field observations will be made at Kuttara volcano, then at Usu volcano and\/or Tarumae volcano .<\/p>\n\n\n\n<p>&nbsp;<\/p>\n\n\n\n<h4 class=\"block-heading\">For further informations regading the workshop see the&nbsp;<a href=\"https:\/\/drive.google.com\/file\/d\/1SYKaPXJaALMWShuvFYDcHZzbKZCrxILw\/view?usp=sharing\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>1st circular<\/strong><\/a>, <a href=\"https:\/\/drive.google.com\/file\/d\/1gCuFiOQBv-S_FJVzf-4YgMZRFi2Q81rE\/view?usp=sharing\" target=\"_blank\" rel=\"noopener\"><strong>2nd circular<\/strong><\/a> and <a href=\"https:\/\/drive.google.com\/file\/d\/12nnbxon67b9umnWzA8aw6h6XdWDQD0Sq\/view?usp=sharing\" target=\"_blank\" rel=\"noopener\"><strong>3rd circular<\/strong><\/a>.<\/h4>\n\n\n\n<h4 class=\"block-heading\">The official workshop webpage is <strong><a href=\"https:\/\/sites.google.com\/g.ecc.u-tokyo.ac.jp\/gasworkshop15\/home\" target=\"_blank\" rel=\"noopener\">https:\/\/sites.google.com\/g.ecc.u-tokyo.ac.jp\/gasworkshop15\/home<\/a><\/strong>.<\/h4>\n\n\n\n<h4 class=\"block-heading\">The report and the program are accessible here: <a href=\"https:\/\/ccvg.iavceivolcano.org\/content\/uploads\/sites\/7\/2025\/09\/report_on_the_15h_workshop_ccvg_final.pdf\">Report<\/a>, <a href=\"https:\/\/ccvg.iavceivolcano.org\/content\/uploads\/sites\/7\/2025\/09\/ccvg2025_program_abstracts_v2.pdf\">Program<\/a>.&nbsp;<\/h4>\n\n\n\n<h2 class=\"block-heading\">&nbsp;<\/h2>\n\n\n\n<p><strong><em>Scientific Program<\/em><\/strong> <br>We hope the conference will be an opportunity to represent a wide range of scientific activities around the study of volcanic gases. As a guide, we aim to organize the presentations around the following topics: (1) geochemistry of magmatic gases and fluxes, (2) new observational techniques, (3) atmospheric chemistry of volcanic plumes, and (4) interpretation and modeling of volcanic processes with complementary datasets.<\/p>\n\n\n\n<p><strong><em>Field campaigns<\/em><\/strong><br>1. Direct sampling of gas or hot springs (Kuttara, Tarumae, Usu) <br>2. Volcanic gas composition measurements using Multi-GAS or other sensor systems (Kuttara, Tarumae) <br>3. Plume measurements using UV remote sensing techniques such as DOAS (Tarumae) <br>4. Measurements of diffuse soil degassing especially CO2 (Usu)<\/p>\n\n\n\n<p><strong><em>Tentative Schedule<\/em><\/strong><br>Starting Date: August 31, 2025 <br>Day 1: Arrival at Sapporo &amp; Ice Breaker party in Sapporo: Stay at Sapporo<br>Day 2: Scientific Meeting in Sapporo: Stay at Sapporo<br>Day 3: Scientific Meeting in Sapporo: Stay at Sapporo<br>Day 4:Field work at Kuttara volcano: Stay at Lake Toya<br>Day 5: Field work at Tarumae or Usu volcanoes: Stay at Lake Toya<br>Day 6: Field work at Tarumae or Usu volcanoes: Stay at Lake Toya<br>Day 7: Closing meeting and discussion, Fairwell Party: Stay at Lake Toya<br>Day 8: Morning: Transport to New Chitose Airport<\/p>\n\n\n\n<p><em><strong>Important dates (tentative)<\/strong><\/em> <br>October 2024 &ndash; Second Circular <br>February 2025 &ndash; Pre-registration \/ Abstract submission open <br>April 2025 &ndash; Abstract submission close <br>May 2025 &ndash; Registration close<\/p>\n\n\n\n<p><em><strong>Local organizing committee<\/strong><\/em> <br>Toshiya MORI (Univ.
