Outline of Research at the Start

先行研究で開発した離島火山観測システムに対し、遠望観測のリアルタイム化、ハイドロフォンのアレイ化といった性能強化と更なる多項目化を図る。この開発・製作と並行して、3つの火山(伊豆大島・鬼界カルデラ火山・クラカタウ火山)の周辺海域で観測を実施し、Iridium及びThuraya衛星経由で逐次取得されるデータ解析によって各項目の性能評価および検証を行う。クラカタウ火山観測期間中は噴火活動の継続も予想されるため、リアルタイム監視に基づいた情報発信を随時行う。また活動状況次第では、観測時期を変更する可能性も想定している。最終的には、国内外の気象庁業務に活用可能な実用化レベルの監視手法の構築を目指す。

Outline of Final Research Achievements

In order to understand the process of volcanic tsunami generation, which is conventionally difficult to predict, we have developed a highly mobile real-time activity observation system for observation near the tsunami generation site and operated the system in the actual sea area. During the observations, we also developed data analysis methods for atmospheric and underwater sound waves and camera images acquired via satellite at all times, as well as methods for the immediate detection of volcanic tsunamis. On the other hand, during the large-scale eruption of, Hunga Tonga-Hunga Ha'apai volcano volcano, on January 15, 2022, we succeeded in capturing the entire eruption process using an underwater hydrophone array observation network (MERMAID) deployed in the vicinity, and identified its location and estimated its source time function based on the earthquakes associated with the eruption.

Academic Significance and Societal Importance of the Research Achievements

火山性津波は地震性津波とは異なり、先行地震動を伴わないばかりでなく、発生機構が多様であるため、沿岸での到来時刻及び規模の予報が困難となり、これまで数多くの重大な災害を引き起こしてきた。火山性津波による災害軽減には、津波発生に至る過程の理解が不可欠であり、これに資するには、津波発生後に迅速にかつ正確に予測するシステムの構築が必要である。世界における活動的火山の3割が島嶼に在り、その殆どが津波発生ポテンシャルの高い環太平洋島弧上の成層火山またはカルデラ火山である。火山性津波が孕む突発的災害への対応に必要な機動力と、火山活動の将来予測に不可欠な連続即時監視能力を備えた本システムの果たす役割は大きい。
