Research on earthquake–volcano interactions is in its infancy, and limitations on available data constrain our present ability to decide between competing models for interaction processes. Progress will depend to a large degree on the whims of nature for “repeat experiments” at suitably instrumented volcanoes. . . A more definitive answer must thus await the response to future large earthquakes of multiple volcanic systems that are well-monitored with multi-parameter instrumentation.

1707 Hōei earthquake, which occurred at 14:00 local time on October 28, 1707, was the largest in Japanese history[1] until the 2011 Tōhoku earthquake[2] surpassed it.

Earthquakes and volcanoes are inexorably linked through plate tectonics, with the major seismic and volcanic belts concentrated along the boundaries between plates.

Metropolitan Museum of Art’s (New York) writes on “The Great Wave at Kanagawa” : The turbulent wave seems to tower above the viewer, whereas the tiny stable pyramid of Mount Fuji sits in the distance. The eternal mountain is envisioned in a single moment frozen in time.
Hokusai characteristically cast a traditional theme in a novel interpretation. In the traditional “meisho-e” (scene of a famous place), Mount Fuji was always the focus of the composition. Hokusai inventively inverted this formula and positioned a small Mount Fuji within the midst of a thundering seascape.
Foundering among the great waves are three boats thought to be barges conveying fish from the southern islands of Edo (modern Tokyo). Thus a scene of everyday labor is grafted onto the seascape view of the mountain.

A large, shallow earthquake (mag 6.2) occurred under the SSW flank of Mt Fuji on 15th March 2011.
1707 Eruption
On 26th October 1707 there was a magnitude 8.4 earthquake hit Honshu, Japan. This was followed by several smaller earthquakes around Mt Fuji. An eruption began on 16th December 1707 on the SE flank of the volcano accompanied by pumice fall. After 6 hours the pumice fall changed to scoria fall. On the first day of the eruption, 72 houses and three Buddhist temples were destroyed in the town of Subassiri 10 km from the volcano.
Violent eruptions were recorded between 25-27 December. The eruption ended on 1st January 1708. No pyroclastic flows or lava flows were formed during the eruption.
Tephra from the 1707 eruption fell over the south Kanto plain, Tokyo, and NW Pacific ocean 280 km from the volcano. The total volume erupted over 16 days was 0.68 cubic km of dense rock equivalent.
