t h a n 700 000 (volcanic) earthquakes were observed. At (he same time
remarkable contortion of the ground also took place together with other
strange geophysical phenomena. In the course of these events, volcano
Asama-yama (one of the most active volcanoes of the world) showed a perfect
inactivity. This volcano is situated at a distance of about 30 km measured
from Matsushiro, that is very near the site of the events. In the paper a
causal relationship is suggested between the geophysical phenomena at .Matsushiro
and the inactivity of Asama-yama. Two alternative possibilites are
t r e a t e d briefly. The hypothetical character of these ideas is strongly emphasized
by the author, however both possibilities appear to be physically real
and can explain all the important geophysical events observed on the spot.
