Over the past 30 days, Tonga has recorded 27 earthquakes of magnitude 2.5 or greater in our tracker. 2 reached magnitude 5.0 or higher. 25 landed between M4.0 and M4.9. By depth: 4 shallow (<70 km), 10 intermediate (70–300 km), 13 deep-focus (>300 km). 8 of the epicenters were offshore. 1 event produced at least one felt report, totalling 1 citizen submissions to the USGS Did You Feel It? system. Focal depths ranged from 10.0 km to 602.5 km. All 27 solutions have been reviewed by a USGS seismologist.
Leading the list is a magnitude 5.4 event near 176 km ESE of Neiafu, Tonga at 10.0 km depth and triggered a green PAGER alert. The second-ranked event, at magnitude 5.3 near 280 km WNW of Neiafu, Tonga, trails by 0.1 magnitude units — a narrow gap, indicating two comparably energetic events in the current window. Rounding out the top three is a magnitude 4.9 earthquake near 78 km SE of Pangai, Tonga.
