This system has come at a cost of one billion dollars.
Each sensor has an accelerometer that measures tremors and algorithms that detect earthquakes.
When an earthquake is detected a signal is sent to a server in hundredths of a second.
The damage maps are sent via email to fire departments within minutes of the earthquake and are downloaded to battery-powered devices in case power is interrupted.
IoT standalone sensors are augmented by Zizmos smartphone apps Zizmos eQuake that are available free-of-charge for iOS and Android.
Every second that passes, thousands of messages are sent from the sensors to servers for analytics and alerting.
