Methods and systems for using a portable device with communication capability and motion detection to act as an emergency alert system by detecting a button press or shaking of the device or other user actions and taking appropriate actions are disclosed. The portable device may take independent action such as calling a telephone number or sending a message when the alert is activated. The portable device may also communicate with an emergency alert server to take various configured emergency actions in response to an event. |
