Types of volcanic eruptions in Japan

Revisiting Mt Fuji’s groundwater origins with helium, vanadium and environmental DNA tracers

“…1 ). Due to this unique geologic setting, Fuji consists primarily of basalt and is much more permeable than other arc stratovolcanoes, which are mostly composed of poorly permeable andesitic magmas 5 – 13 . Owing to its long passage through basalt 14 , Fuji’s groundwater is very soft and strongly enriched in vanadium, making Fuji’s rivers the most vanadium enriched on Earth 15 – 17 .…”

Remarks on elements of Japanese landscape and their geotouristic attractiveness

“…The geological structure and surface features of the Japanese islands are also shaped by continuous volcanic processes, which affect the present landscape of the archipelago (Uhira et.al., 2004;Minakami, 1964;Tsuya, Morimoto, 1963;Geshi et.al., 2002). The territory of the country comprises almost 260 volcanoes, including between 40 and 80 volcanoes which show continuous activity (Tab.…”

“…Ciągle aktywne procesy wulkaniczne pozostawiają wyraźne ślady we współczesnym krajobrazie (Fig. 3) archipelagu (Uhira et al, 2004;Minakami, 1964;Tsuya, Morimoto, 1963;Geshi et al, 2002). Na terytorium tego kraju znajduje si� blisko 260 wulkanów (aktywnych jest od 40 do 80), z czego najwyższym i najsłynniejszym jest Fudżi (Machida, 2002;Koyama, 1998;Ukawa, 2005;Słowakiewicz, Motonaga, 2008).…”

The Behavior of Silicon, Aluminum, Iron, Magnesium, Calcium, Sodium and Potassium in Fumarolic Gas at the Mihara Volcano, Japan

“…Mihara have been made in detail by Tsuboi,15) Iwasaki,16) Tsuya,17) Kuno18) and many other investigators. [19][20][21] Since the eruption in 1957, however, the volcano has been dormant; recently only a small amount of ashes is sometimes ejected from the crater. There are many fumaroles along the cracks on the scoria cone in the southwestern part of the crater.…”
