The coronavirus pandemic has prompted several governments to take the major step of asking everyone to stay home except for essential needs. This has brought down the ground vibration significantly, in various frequency bands, particularly at higher frequencies related to anthropogenic seismic noise. The power is reduced by ~ 5 dB at 10 Hz in Shillong, India, post-lockdown (after 25 March 2020) in India. This is lower than the levels that are observed over the weekends. On the day of Janata Curfew (22 March 2020), the reduction in power is ~ 10 dB at 10 Hz.
新冠疫情促使多个政府采取重大举措，要求除满足基本需求外，所有人都居家隔离。这使得地面振动在各个频段都显著降低，尤其是在与人为地震噪声相关的较高频率处。印度封锁后（2020年3月25日之后），印度西隆在10赫兹处的功率降低了约5分贝。这低于周末观测到的水平。在全民宵禁日（2020年3月22日），10赫兹处的功率降低约10分贝。
