We are a small team from Antalya, Turkey, building the world's densest earthquake early warning sensor network through community participation and open-source technology.
On February 6, 2023, two devastating earthquakes struck southeastern Turkey and northern Syria, claiming over 50,000 lives. In many affected areas, people had no warning at all. The official earthquake monitoring infrastructure, while scientifically precise, was too sparse to provide the seconds of advance notice that can mean the difference between life and death.
That tragedy became our founding motivation. We asked a simple question: What if thousands of low-cost sensors could fill the gaps that a handful of expensive seismometers cannot?
GeoShake was born from this idea. Instead of relying on a few high-precision instruments, we build a dense network of affordable ESP32-based sensors. Each device costs a fraction of traditional seismic equipment, yet when hundreds of them detect a P-wave simultaneously, the network can identify an earthquake's origin faster than any single station ever could.
Founded in 2025 under Appflows Technology Inc., GeoShake is headquartered at Akdeniz University's Ulugbey R&D Center in Antalya. Our sensor network has grown to 100+ active stations across Turkey, and every line of code, every circuit schematic, and every algorithm is open source.
GeoShake is designed and built by Hüseyin Tamer, working out of the Akdeniz University Uluğbey R&D Center in Antalya — from the sensor hardware and firmware to the network that connects it all. Questions about the project land on his desk: say hello any time.
LinkedInGeoShake is released under the MIT License. Our firmware, mobile app, backend services, hardware schematics, and detection algorithms are all publicly available. We believe that earthquake early warning is too important to be locked behind proprietary walls. Anyone can audit, improve, or fork the project.
Every new sensor makes the network stronger. Register your station and help build a denser, faster earthquake early warning system for everyone.
