我们的星球不停地振动，有时是显著的，但更多的时候是难以察觉的强度。传统的地震学试图通过研究地震图（用地震仪测量的振动记录）来解释振动源和路径效应。在这样做的过程中，科学家们要么试图了解导致强烈地面运动和地震破坏的构造过程（1），要么探索否则无法进入的行星内部（2）。这些研究领域的进展通常依赖于大地震的罕见和地理上的不规则发生。然而，地球表面的人类活动也会产生地震波，仪器可以在很远的距离检测到。第1338章这一次，李明博(3)关于自严重急性呼吸系统综合征冠状病毒2型（SARS-CoV-2）大流行开始以来人为振动平静的报告。
Our planet vibrates incessantly, sometimes with notable but more often with imperceptible intensity. Conventional seismology attempts to decipher vibrational sources and path effects by studying seismograms—records of vibrations measured with seismometers. In doing so, scientists seek either to understand the tectonic processes that lead to strong ground motions and earthquake failure (1) or to probe otherwise inaccessible planetary interiors (2). Progress in these areas of research typically has relied on the rare and geographically irregular occurrence of large earthquakes. However, anthropogenic (human) activities at Earth's surface also generate seismic waves that instruments can detect over great distances. On page 1338 of this issue, Lecocqet al.(3) report on a quieting of anthropogenic vibrations since the start of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic.
