No significant hypocenter migration — activity is stationary (R²=0.00, n=90); no sign of a propagating dike. Migration shows automatically if R²≥0.30.

Note: before February 2026 about half of events lacked an automatic magnitude, so magnitude-dependent figures (b-value, count of M≥X) under-count earlier periods — the catalogue is not homogeneous across this window. Cumulative moment is barely affected.

This is a reduced view: it is built from the daily aggregate (counts, moment, magnitude bands, depth histogram) rather than individual events. Map points, the depth scatter, cross-sections and the migration fit are therefore missing — they need each event's location and depth. Counts, total moment and the b-value are exact, not approximated.

Depth is automatic and uncertain; earthquakes alone do not show magma movement — deformation (GPS) and gas are needed. Grey points: automatic fixed-depth values. b-value computed for M≥1.5 (automatic magnitudes make lower completeness unreliable). Preliminary data.
Independent confirmation (EMSC / USGS)
Of our 19 M≥3 events in the last 90 days, 18 are also listed by EMSC or USGS (independent catalogues). Magnitudes do not match exactly — EMSC/USGS report mb/ML/Mw, Skjálftalísa automatic m_autmag.
