Mt. Tsurumi / Mt. Garan Volcanic Disaster Prevention Map
Mt. Tsurumi and Mt. Garan are active volcanoes. We have to prepare for volcanic eruptions on a daily basis in
order to prevent damage from volcanic activities.
We have prepared this Volcanic Disaster Prevention Map to distribute volcanic information to local residents and to
reinforce the city’s disaster prevention measures in case of emergency.

Expected Mudslide Area
泥流災害予想区域
Expected Area of Mudslide and Volcanic Gas
降灰10-20cm
Predicted based on information from other volcano records.
Mt. Tsurumi: Predicted based on the eruption that took place about 1200 years ago
Mt. Garan: Predicted based on the volcanic action in 867 C.E. (ash fall only)
Mudslide:
Mudslide caused by rain after volcanic ash has accumulated on the
slope are predicted.

Predicted Conditions
for the Volcanic Disaster Prevention Map
Cinder:
境川
Area where lava flow may reach
Generally, lava flows slowly, so
you might be able to evacuate
on foot. Pay at tention to
volcanic information for proper
evacuation.
Pyroclastic surge
(fiery winds around the
body of the pyroclastic surge)
With the top velocity reaching
more than 100 km/h, pyroclastic
flows burn ever y thing they
reach. You must evacuate before
this frightening phenomenon
occurs.
Area where mudslide
may flood
Just a small amount of rainfall
could cause mudslide after a
volcanic eruption. Evacuate if
rain is expected af ter the
eruption.

Area where volcanic gas
may reach
A high-temperature mudflow
gushes out of the mud volcano
and runs down.
Do not get close to the
surrounding area of the crater
where volcanic gas is emitted
or areas where gas easily
stagnates such as hollows.
