Worldwide earthquakes above magnitude 3 during the past 24 hours on 23 Aug 2025
Summary: 1 quake 7.0+, 7 quakes 5.0+, 43 quakes 4.0+, 138 quakes 3.0+, 347 quakes 2.0+ (536 total)
A powerful magnitude 7.5 earthquake struck the Drake Passage—between South America and Antarctica—early today, triggering a tsunami alert for parts of Chile’s coastline. The Pacific Tsunami Warning Center warned of possible waves within three hours, and authorities remain on alert (Economic Times).
Meanwhile, aggregated data show a particularly active seismic day, with at least one quake above M7, around five above M5, and dozens more in the moderate range. According to our monitoring system, more than 1,800 earthquakes were detected in the past 24 hours, underscoring the global scale of seismic activity.
Other noteworthy tremors included a M5.3 near Mawlaik, Myanmar, and several magnitude-5 events in the South Shetland Islands region. While these quakes drew scientific attention, no major damage or casualties have been reported.
Despite the high numbers, today’s seismic activity was otherwise geographically dispersed and largely non-impactful—save for the Drake Passage and tsunami advisory, which remains the most significant event of the day.
