Tsunami Trace Database.
1.
Objective of the Database
In order to use the Tsunami Trace Data (data on
locations of traces hit by tsunami in the past) for the safety assessment of
nuclear power plants and other facilities, Tohoku University’s School of
Engineering and the Japan Nuclear Energy Safety Organization (JNES) have
developed the Tsunami Trace Database (hereinafter referred to as the “Database”)
in cooperation with tsunami experts. About 20,000 trace data of tsunami
registered in the Database are each given a reliability rating based on a detailed
review by tsunami experts. Consequently, the Database, which is managed with a
database management system based on Web-GIS, is designed to enable users to
search for and retrieve reliable tsunami trace data in accordance with their objectives.
In order to provide the results of our research not only for research into
nuclear safety or tsunami, but also to local governments for tsunami disaster
prevention and residents living in coastal areas to prevent tsunami disasters,
we have released the data in the Database in stages from October 2010 onward.
Users of the Database are required to observe the
following conditions.
2.
Terms of Use
(1) Intellectual property rights
The intellectual property rights regarding the
Database belong to Tohoku University’s School of Engineering and the Japan
Nuclear Energy Safety Organization (JNES). The copyright for the figures and
photographs registered that were originally produced for the Database also
belongs to Tohoku University’s School of Engineering and JNES.
The copyright for the data, including trace information,
photographs, figures and tables, that are included in the articles and
documents registered in the Database generally belongs to the authors,
photographers or writers who produced said data. Accordingly, the data are all
registered in the Database with the permission of copyright holders.
(2)
Approved usage of the Database
Users of the Database are permitted to search for
and retrieve tsunami trace information and to download files from this website
under the conditions specified in these terms of use.
(3)
Usage restrictions
It is forbidden to use this website in any way or
for any purpose that violates laws, ordinances or public policy.
When presenting, duplicating, loaning or selling
tsunami trace information to third parties (including operations conducted via
electronic media or networks), users of the Database must explicitly indicate
that the information was taken from the Tsunami Trace Database.
Users of tsunami trace data from this website protected
by copyright must observe the following conditions:
■ Obligation to provide citations
When presenting publications and websites that
contain results obtained from the Database or files downloaded from this
website, users must explicitly indicate that they have taken data from the
Database, regardless of whether they are presenting the information in
publications, websites or other media.
■ Prohibition of duplication, etc.
Users are not allowed to do the following without
written permission:
(1) Duplicating databases or downloaded files in
order to distribute them to third parties
(2) Using databases or downloaded files for online
services open to persons other than users themselves
(3) Using databases or downloaded files in order to
sell products or services (commercial usage)
(4)
Disclaimers
Information registered in the Database is collected
and organized by Tohoku University’s School of Engineering and JNES from data
recorded in existing documents. Records on individual traces are each given a
reliability rating by conducting field and document surveys where necessary and
that is based on a review by the Tsunami Trace Database Review Committee.
Tohoku University’s School of Engineering, JNES and
the Tsunami Trace Database Review Committee bear no responsibility for loss or
damage related to the use of the Database or files downloaded from this
website. Since the Database is still under development, there is a possibility
that some of the registered data may be corrected during future document and
field surveys.

Cautions
i) Accuracy of trace data
The locations (longitudes and latitudes) of tsunami
traces in the Database are identified (or estimated) as accurately as possible
based on information obtained from the place names (or area names) provided in
documents and attached maps, and also by conducting additional surveys if
necessary.
- Locations of traces hit by tsunami cannot be
pinpointed in some of the cases included in the Database due to the lack of
appropriate information or maps in documents or as a result of names of large
areas being recorded in documents instead of more specific place names.
- When using individual tsunami trace data,
especially for the purpose of checking the results of a numerical analysis of
tsunami (tsunami simulation analysis), users are recommended to use the data in
combination with not only information on the heights (numerical values) of
tsunami and their locations (longitudes and latitudes), but also with the
reliability ratings assigned to individual trace data.
- The Database includes data on major tsunami that
occurred from 1596 AD onward, and the names of places (or areas) recorded in
documents may differ from their current names. Although we conduct surveys to
check registered location information as far as is possible, users are
recommended to study the original documents for themselves.
ii) Registration
and release of tsunami trace data
We are gradually registering and releasing data for
the Database, beginning with large tsunami that had serious effects on coastal
areas. To date, we have registered tsunami trace data on more than 20,000
locations and are gradually releasing these data, starting with those that have
been assigned reliability ratings based on a close review by tsunami experts.
When using these data, please be aware that the numbers of tsunami records
registered and released for some locations may be smaller than the numbers of
tsunami actually recorded. Users should also take note that the data registered
in the Database do not cover all tsunami trace data in Japan.
Although we make every effort to avoid errors and
mistakes when entering data into our database, please let us know if you have
noticed any errors or mistakes. Please also note, however, that we do not bear
any responsibility for loss or damage resulting from the use of the Database.
iii) Server maintenance and other operations
The Database may be temporarily shut down for
server maintenance and other system management operations. Users will be
notified in advance of such temporary shutdowns.
(6) Linking to the website
There is no particular procedure required to link
to the Database, except that the destination of the link should be set to: <https://tsunami-db.irides.tohoku.ac.jp>
(7) Other
Matters that are not specified in these terms of
use and unclear issues regarding these terms of use shall be settled by
consultations between the parties concerned.
