USGS Earthquakes
usgs-earthquakes // count
In the past 24 hours, 61 earthquakes of magnitude 2.5 or stronger were detected worldwide, which is right at the expected daily average of 60 and within the normal short-term range. However, this count sits notably above the long-term historical band of 38–56 earthquakes per day, indicating that earthquake activity over recent weeks or months has been running elevated compared to the baseline—the strongest quake in this period was a 6.6 magnitude event near the South Shetland Islands. While today's count itself is unremarkable, the sustained higher-than-normal activity pattern warrants continued monitoring to determine if this represents a temporary cluster or a shift in seismic behavior.
M2.5+ earthquake count in last 24h via USGS
64 M2.5+ quakes in 24h, within normal range
64 M2.5+ quakes in 24h — 1.4× normal, significantly above baseline
63 M2.5+ quakes in 24h, within normal range
62 M2.5+ quakes in 24h — 1.3× normal, significantly above baseline
60 M2.5+ quakes in 24h, within normal range
USGS earthquake activity has shifted from normal to drift status with 60 M2.5+ earthquakes in the last 24 hours, exceeding the 47-count expected value and both the short and long-term bands of 38-56, driven by a 6.6 magnitude event near the South Shetland Islands. The score of 2.92 indicates moderately elevated seismic activity above baseline patterns.

USGS earthquake count returned to normal status after a brief drift period, with 53 M2.5+ events in the last 24 hours slightly below the 54-count expectation but well within the normal short-term band of 51.84-56.16. The -0.93 score indicates minimal deviation, and the strong long-term score of 1.35 confirms seismic activity remains in expected ranges despite a notable 6.6 magnitude event near the South Shetland Islands.
USGS earthquake count increased to 54 (up from expected 47), triggering a drift signal with score 1.57, though activity remains within the normal long-term band of 38.10–55.90. The shift is driven primarily by a 6.6 magnitude event near the South Shetland Islands, representing a short-term elevation rather than sustained anomalous seismic activity.

M2.5+ earthquake activity dropped to 45 events in the last 24 hours versus an expected 53, with a score of -1.35 indicating below-average seismic activity. The signal transitioned from drift status back to normal as counts remain well within the 41.14–64.86 band, though the largest recorded event was a magnitude 5.6 near Russia's Kuril Islands.
44 M2.5+ quakes in 24h, drifting below normal (0.8× expected)
USGS M2.5+ earthquake activity returned to normal status with 45 recorded events in the last 24 hours, slightly above the expected 44 count and well within the short-term band of 42.24–45.76. The transition from drift status reflects stabilization despite a notable 5.6 magnitude event occurring 167 km south of Severo-Kuril'sk, Russia, with the long-term score of -1.35 indicating seismic activity remains subdued relative to historical patterns.
