Submission declined on 25 March 2026 by Awesomecat (talk). This draft's references do not show that the subject meets Wikipedia's criteria for inclusion. The draft requires multiple published secondary sources that: provide significant coverage: discuss the subject in detail, not just brief mentions or routine announcements; are reliable: from reputable outlets with editorial oversight; are independent: not connected to the subject, such as interviews, press releases, the subject's own website, or sponsored content. Please add references that meet all three of these criteria. If none exist, the subject is not yet suitable for Wikipedia. If you would like to continue working on the submission, click on the "Edit" tab at the top of the window. If you have not resolved the issues listed above, your draft will be declined again and potentially deleted. If you need extra help, please ask us a question at the AfC Help Desk or get live help from experienced editors.

• Comment: You need to find reliable secondary sources not published or created by GeoShake. The official website, GitHub, Apple, and Play Store links don’t help. Awesomecat (✉ / ✎) 18:07, 25 March 2026 (UTC)

GeoShake is an open-source earthquake early warning sensor network developed by Appflows Technology Inc., based in Antalya, Turkey. Founded in 2025, the project uses a dense network of low-cost MEMS accelerometers to detect P-waves and issue alerts seconds before strong shaking arrives.^[1] The project distributes a companion mobile application on both Google Play^[2] and the Apple App Store.^[3]

Rather than relying on a small number of expensive professional seismometers, GeoShake deploys large quantities of affordable sensor stations. Each GeoShake T1 device contains an ESP32-S3 microcontroller and four STMicroelectronics LSM6DSO 6-axis MEMS accelerometers sampling at 208 Hz. The four-sensor array reduces effective noise to approximately 35 ug/sqrt(Hz) through averaging.^[1]

When a potential seismic event occurs, the system applies a correlation algorithm: if multiple devices within a geographic radius report similar acceleration signals within milliseconds, the system classifies the event as an earthquake rather than local noise. Data transmission uses the MQTT protocol over Wi-Fi with TLS encryption.^[1]

GeoShake provides a companion mobile application for iOS^[3] and Android^[2] that delivers real-time earthquake alerts via push notifications. The app includes a live seismic event map showing sensor station data, configurable alarm thresholds based on earthquake magnitude and distance, and support for four languages (English, Turkish, Spanish, and Indonesian). The app communicates with the sensor network over MQTT for sub-second alert delivery.^[1]

GeoShake was founded in 2025 and is headquartered at Akdeniz University's Ulugbey Research and Development Center in the Konyaalti district of Antalya. The project collaborates with the university's Geophysics Department on algorithm validation and false alarm reduction research.^[1]

All firmware, hardware schematics, mobile applications, and detection algorithms are released under the MIT License and hosted on GitHub.^[4]
