You can get small raspberry pi based seismographs from https://raspberryshake.org/ ... could be interesting to integrate it with a small alarms or web/mobile apps that go off when it detects p-wave/s-wave arrivals with amplitudes above a user-specified threshold (so its not going off every day with smaller/distant events that are not felt by humans at the measurement location)
