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 TEKNOLOJİ ANONİM ŞİRKETİ, GeoShake is headquartered at Akdeniz University's Ulugbey R&D Center in Antalya. Our sensor network has grown to 500+ active sensors worldwide. Our firmware and detection algorithms are open source, and our enclosure designs are freely available for anyone to print and modify.
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.
LinkedInOur firmware is released under the GPL-3.0 licence and our enclosure designs under CC BY-SA 4.0. The firmware, the signal-processing reference it is bit-locked to, and the detection algorithms are all publicly available, so anyone can audit, improve or fork them. Our PCB design and cloud backend remain proprietary. We believe earthquake early warning is too important to be locked entirely behind proprietary walls.
Every new sensor makes the network stronger. Register your station and help build a denser, faster earthquake early warning system for everyone.
