All of Iceland
Seismicity across all of Iceland by period · data from Skjálftalísa (Icelandic Met Office)
Points = earthquake locations in the selected window, coloured by magnitude: M3+ · M2+ · smaller (a sample if more than 800).

No significant hypocenter migration — activity is stationary (R²=0.06, n=130); no sign of a propagating dike. Migration shows automatically if R²≥0.30.
Depth (0 km at top). Grey: fixed depth.
Magnitude distribution
Depth cross-sections — color by age (orange=newest, grey=older), point size by M. Rising cluster = possible magma intrusion.

Gutenberg-Richter b ≈ 0.79 ± 0.06 (i.e. likely 0.73–0.85, M≥1.7, n=89) · low b can accompany magma activity (small sample, interpret with caution)

Magnitude distribution
Depth cross-sections — color by age (orange=newest, grey=older), point size by M. Rising cluster = possible magma intrusion.
Gutenberg-Richter b ≈ 0.96 ± 0.02 (i.e. likely 0.94–0.98, M≥1.7, n=2623)
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.

Gutenberg-Richter b ≈ 0.93 ± 0.01 (i.e. likely 0.92–0.94, M≥1.7, n=5010)
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.
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 57 M≥3 events in the last 90 days, 35 are also listed by EMSC or USGS (independent catalogues). Magnitudes do not match exactly — EMSC/USGS report mb/ML/Mw, Skjálftalísa automatic m_autmag.
