2022 Tonga eruption seismicity and seismic stations

(a) The three closest seismic stations (red inverted triangles) to the Tonga eruption are more than ~760 km (~472 mi) away. (b) The timeline of earthquakes (yellow circles) at the Tonga eruption site shows the increase of seismicity immediately after the M5.8 during the initial eruption, followed by decreasing seismicity after the first couple of weeks.
