Hello Tom,
go to ebay and get a cheap geophone. Attach a resistor in parallel acc. datasheet, and use a data logger (simple: HX711 weigh scale ADC plus two resistors to fake a bridge circuit, arduino for interrogation and logging to PC) and you will have knowledge about the short-term events at your location. You might gain enough knowledge to be able to compensate for the movements by postprocessing. Or, nut-conorm, you might put your clocks and the geophone on a table which rests on, say, elastomer in parallel to a voice coil actuator, applying some control theory magic, have the arduino (or something analog or a mix) use the geophone feedback for the voice coil to keep the table aligned.
