Seismicity by period · derived statistics from Skjálftalísa (Icelandic Met Office)
Status (automatic)
No particular signs of unrest in the last 24 hours — 1 earthquake recorded, within the system's normal range.Central volcano between Hekla and Eyjafjallajökull. No eruptions in historical time. (overview — more at vedur.is) · circle on the map = rough outline of the system (radius).
Subglacial system: a subglacial eruption can cause a jökulhlaup (sudden glacial meltwater flood) with little warning, and volcanic gases (incl. SO₂, CO₂) can be dangerous near vents and may pool in hollows. These are standing features of the system, not a sign of an imminent eruption.
📜 Did you know?
Tindfjallajökull is the smallest glacier-capped central volcano in Iceland, its highest peak Ýmir reaching 1,462 m. It is an old, deeply eroded central volcano with a caldera, richer in silicic rock (rhyolite) than most neighbouring systems. No eruption is known there in historical time.
Points = earthquake locations in the selected window, coloured by magnitude: M3+ · M2+ · smaller (a sample if more than 800).

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.

What do the numbers mean — and what should I do?
β (swarm signal): how high activity is versus the area's 2-year average. β above 2 means an ongoing swarm. It measures activity, not a forecast of a large quake.
Cumulative moment (Mw): the combined energy of the quakes in the period. Uplift (GNSS): whether the ground is rising or sinking, mm per year — the data are a few weeks old. Some systems (e.g. Svartsengi) deform in steps during eruption cycles rather than at a steady annual rate.
Swarm character is computed for a whole volcanic belt, not a single system — it describes the belt, not necessarily this one system.
What should I do? This is automatic monitoring for information — not an official warning. Follow official information from the Icelandic Met Office and Civil Protection (112).
