Monitoring Number of Runners in a Park using Continuous Seismic Data

Abstract

This paper addresses monitoring human activity as a new way to use seismometers. We estimated the variation of the number of people running in the park by detecting the vibration associated with human steps using the permanent seismic observation data. As a result, the number of runners increased until 2012, then decreased until 2019, and then dramatically increased during the state of emergency in response to the COVID-19. Our seismometer-based monitoring provides the information about human activity anonymously and contributes to additional output of permanent seismometer data.
