Mt. Fugen of Unzen Volcano
suddenly burst into
eruption on 17 November 1990,
after 198 years of
quiescence.
It presented varied aspects of
volcanic activities,
the successive extrusion
of lava,
the growth of lava domes,
the large-scale pyroclastic flows
and the debris flows
occurred frequently.
This volcanic eruption
caused serious disaster
and great havoc of
wealthy land
and peaceful life
in the Shimabara area,
including the lives
of 44 people.
Considering the scale of
the eruption, we can say
that this is the largest
eruption in several thousands years.
Many scientists in Kyushu University,
especially from Shimabara
Earthquake and Volcano
Observatory, in cooperation
with other scientists
from all over Japan,
collected a huge amount of
information and data
concerning the eruption
during the period
from the precursory phenomena
through the cease of
movement of magma.
In order to
publish a part of these data
to the city people
and to attract their
attention to geohazard,
we here open this exhibition.
This is one of the trials to show
the past,
the present
and the future
of the high-level
researches in Kyushu University.
I cordially hope
you to enjoy this exhibition.
