Seismicity for 2021 has been analyzed, quality controlled, and cataloged (figure 1). Despite the largest U.S. earthquake in more than 50 years, a magnitude 8.2 southwest of Kodiak Island, 2021 ranked fourth overall, with 49,120 events, after 2018 (about 55,000), 2019 (about 50,000), and 2020 (about 49,250) (figure 3). That’s not to say that our seismic data analysts weren’t busy.
