The idea of using a network of modern phones equipped with a gyroscope and acceleration sensors to detect seismic activity is not new. Unfortunately, this idea is too futuristic and in real life has not yet found incarnation. However, taking care of the safety of their users, developers are beginning to take the first steps in this direction - for example, Apple in the fifth version of iOS for the Japanese market introduces a unique feature, Earthquake Alert.

Trying to prevent the consequences of strong aftershocks, Japan, like most other countries, has to deal with earthquakes, tracking the situation with the help of an extensive network of complex seismological sensors located throughout the country. Information about abnormal seismic activity is open, but, as is often the case, it does not always reach the consumer on time. Now, by enabling the appropriate option, owners of iOS5 devices in Japan will be able to quickly receive notifications about possible danger.
The technology of push-notifications, which has received widespread in recent years, allows background applications to attract attention and is excellent for alerting in the event of an emergency situation.

Scott Kveton (Scott Kveton), CEO of Urban Airship, a leading player in the market for notifications and related analytics, speaks in favor of the new functionality: “We are currently informing customers of the possible dangers with simple SMS messages. Naturally, sms-ki have a lot of technical limitations. Now, thanks to push notifications, we have the opportunity not only to warn the user, but also, for example, show him a page with a visual evacuation plan, and this plan will be personalized, tied to his current location. ”
Service solutions based on push-notifications with geo-referencing will become more widespread and diverse as users switch from regular phones to smartphones. This process is obvious and rather impetuous. The developers hope that in the future such technologies will help save more than a dozen lives only by delivering correct and timely information.
