It's been a tough month for Japan. First the biggest typhoon in 25 years blew through the western region, then a major earthquake in Hokkaido swiftly followed. Both wreaked havoc and recovery is still in process. This month, On Tech takes a look at apps offering disaster prevention information and other services for those looking to stay alert and prepared.

Prevention and information

Yurekuru Call is a Japanese earthquake alarm app that became particularly popular after the Great East Japan Earthquake. With its alert information already available in English, last year the app added an English translation of its +Sonae disaster prevention information service. +Sonae provides advice via easy-to-understand-illustrations and articles that can be accessed via the Yurekuru Call app.
