shield volcano
Honshu (Japan), 34.5°N / 131.6°E 
Summit height: 641 m / 2,103 ft
Aktueller Status: normal / ruhend (1 von 5)
Last update: 6 Jan 2025 (Volcanic Ash Advisory)
Abu volcano is a group of 56 smaller volcanic centers with no individual large central volcano, located near the Japan Sea coast in southwest Honshu, Japan, 80 km west of Hiroshima.
The group, also known as the Abu Monogenetic Volcano Group (AMVG), covers 400 sq km and consists of basaltic-to-dacitic lava flows, small shield volcanoes (some with associated cinder cones) and lava domes. Its total volume is ca. 4 cubic km, with no individual center being larger than 0.5 km3.
Irao-yama (641 m) is the highest peak. Some of the volcanic centers of Abu volcano form offshore islands or submarine vents.
The most recent eruption at the volcano was a central vent explosion at Kasa-yama ca. 8000 years ago.

Beschreibung
Volcanism of the Abu group is believed to be caused by upwelling mantle diapirs, and is is related to subduction of the Philippine Sea Plate. The volcanic group is part of the southwestern Japanese arc, which lies subparallel to the Nankai trough.The erupted magmas of Abu are mainly alkaline basalt and calc-alkaline andesite - dacite in composition.
Eruptions from Abu volcano:
Volcanic activity occurred mainly in 2 phases. An earlier and more intense phase of activity was between ca. 3 and 1.6 million years ago when a quiescent interval followed. The second, less intense phase of activity started about 800,000 years ago and continues into present. The latest known eruption of the AMVG was dated by thermoluminescence at about 8800 years ago.

Anmerkung:
Unsere Liste von Vulkanausbrüchen orientiert sich eng an der Datenbank des Global Volcanism Project (GVP) des Smithsonian Instituts, der international anerkanntesten globalen Datenquelle für Vulkanausbrüche. Sie schließt aber auch bedeutende Eruptionsepisoden oder damit zusammenhängende Vulkanereignisse ein. Unter "Vulkanausbrüchen" versteht man in der Regel meist Serien einzelner Eruptionsepisoden, die zeitlich aufeinander folgen oder sich (bei mehreren beteiligten Ausbruchspunkten an einem Vulkan) auch überlappen können und unter Umständen viele Jahre, Jahrzehnte oder noch länger andauern können. So ist z.B. die aktuelle Tätigkeit des Stromboli als ein einziger Ausbruch verstanden, der seit 1934 anhält.
