Japan Earthquake Real-Time App
JQuake provides unique algorithms, map features, and application preference to give you the information you need, and give it to you in a thought-out, straight-forward manner. Check out how JQuake uniquely handles events and Early Earthquake Bulletins:
Seismic Shaking Detection
Be informed at the split second an earthquake begins! JQuake receives real-time intensity and PGA
updates every second from NIED. This data is used in our earthquake shaking detector, capable of dissociating human-induced vibration from
effective earthquakes. It saves precious seconds, allowing notification even before the Earthquake Early Warning issuance.
Moreover in areas such Okinawa, where unfavorable coverage is met, the algorithm exhibits good detection rates. The sensitivity of the app can be set to detect shaking below human perception and alert users to any size earthquake tremor. Lot of time has been spent on algorithms to ensure that false positives are minimal.
A dynamic and interactive map is available, so the user can manually zoom and navigate. The map uses vector based graphics, so that no network resource are necessary to display it. Additionally the map is rendered with effeciency and is designed to minimize the processing power required by your system.
City names are displayed on the map to facilitate the identification, estimation of real-world geographic location of a shaking event.
When shaking is detected, an automatic zoom is performed to be immediately aware of the situation. If any shaking occurs outside of the view, the application will zooms out to fit all events to the screen. This option can be enabled or disabled based on your viewing preferences.
When a seismic station has a higher value than its neighbors, it is put to forefront for easy reading.
Multiple Event Support
JQuake supports multiple event detection, including displaying multiple Early Earthquake Warning (EEW) bulletins. This helps to insure the display has relevant and consistent information about the events currently unfolding. If multiple bulletins are active, each one will be numbered to distinguish between them.
Realtime Prefecture Intensity List
On the right of the map, a list displaying maximum intensity of each prefecture appears when shaking is detected.
Tsunami Warning display
In the event of a Tsunami Warning in Japan area and upon user preferences, JQuake highlights the coastline according to level of warning : Tsunami Advisory, Tsunami Warning and Major Tsunami Warning. Details about expected arrival times and heights can be found in English when clicking on upper-left panel.
