Target: Notifications will be sent to the users within the area of estimated intensity above 3 when an earthquake occurs. Delivery: Notifications will be sent about 10 to 15 seconds after an earthquake occurs. Limitation: Considering to issue a timely alert for the disaster preparedness, only a few data near the epicenter will be adopted for a rough but quick solution. Hence, there remains some discrepancy between users' feeling and the notifications. Blind Zone: An area around the epicenter that cannot be alerted before the strong shaking starts. Content: Information about the epicenter and the estimated intensity in the regions are all included. Users can view it in the list of Earthquake Early Warning within 7 days.

Target: Notifications will be sent to all users. Delivery: Notifications will be sent about 5 to 10 minutes after an earthquake occurs. Limitation: Considering to issue an official report, all data will be adopted for a careful and complete solution. Hence, it takes longer time to publish the report.

Minor felt earthquake is less affected, so there won't be any notifications for users. Users can either check the latest 15 information in both report in homepage or search the "Earthquake Report Search". Content: All the information such as origin time, earthquake epicenter with latitude and longitude, earthquake magnitude and depth, observed earthquake intensity in the regions will be displayed graphically.

Target: Based on their locations, notifications only appear to part of the users near the area of estimated wave height reaches the threshold. Delivery: Notifications will be sent about 20 minutes after an earthquake, that can cause a tsunami, occurs. Content: All the information such as estimated coastal wave height and tsunami updates will be displayed graphically.
