Here’s some more evidence about what is wrong will the prefecture’s notification system. The colorful image is from the web

and the text image is of information sent out via e-mail, though it can also be found in an archive on the web:

http://www.anshin.pref.kumamoto.jp/rireki/saigai/430000.html

The two types of information (both of which are put out by the prefecture!) use completely different terminology. The lack of a proper correspondence in the information available at the two sources is, at the very least, confusing.
