Seismic Retrofitting

check points apply for your house, have a professional conduct a seismic inspection.

New extensions were built two or more times. A section of the wall or
column was removed for the extension.

It seems like the doors and windows are badly fitted, and the pillars and/

There’s a crack in the wall.
The veranda or balcony is damaged.
Importance of seismic retrofitting to keep from
being crushed to death
Some 80 percent of the people who were killed in the Great Hanshin-Awaji Earthquake
were crushed to death by collapsed buildings. It is said that buildings that were
constructed over 30 years ago, before the new building code for seismic resistance
came into effect on June 1, 1981, have low safety against a major earthquake. These
buildings should be inspected for seismic resistance.

Confirm evacuation places
When evacuation orders are given, or when the danger of fire approaches, you
should evacuate to a temporary evacuation area (e.g. nearby elementary or junior
high schools, parks). If that place becomes dangerous, move to an evacuation area
(e.g. large park or open space). If your home has been damaged and it is difficult to
continue living there, you can live at an evacuation center for a while. It is important
to understand the difference between these three places.

Citizens Disaster Response Team
Example of disaster response goods and equipment
Stocking goods and equipment for disaster response team activities is essential.
Studies on what is necessary are made based on local circumstances. Storage and
management should be done in a manner that will ensure that they can be used flexibly
and promptly in an emergency.

Neighborhood disaster response groups
Groups that are working actively so people can protect themselves and neighbors
can help each other as preparation for an earthquake are designated by the Tokyo
Metropolitan Government as Tokyo Neighborhood Disaster Response Groups. Efforts
are taken to raise community disaster preparedness by holding study meetings with
disaster response specialists and seminars for citizen disaster response team leaders.

What is a volunteer fire corps?
This is a group that undertakes firefighting activities in the community, just
like the fire department does, but unlike the fire department, this is a non-
regular group made up of members who have other occupations, e.g. self-
employed, company employees, homemakers, and students. When a fire,
flood, earthquake, or other kind of emergency arises, they initiate fire-fighting
activities. Inquire at your local volunter fire corps about qualifications needed
to become a member.
