Eastern Volcanic Zone
Zone — systems within: Hekla · Vatnafjöll · Torfajökull · Tindfjallajökull · Eyjafjallajökull · Katla (Mýrdalsjökull) · Vestmannaeyjar · Bárðarbunga · Grímsvötn
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=0.11, n=48); 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 ≈ 0.98 ± 0.06 (i.e. likely 0.92–1.04, M≥1.7, n=241)
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.
