🪨 GeologyBedrock, lava flows, volcanic systems, faults, craters, volcanoes and more from Náttúrufræðistofnun (NSII). Pick one or more sub-layers — nothing is on by default. Regional 1:100k coverage for the Western Volcanic Zone and East Iceland. The legend box is fully adjustable — drag its title bar to move it, pull any edge or corner to resize (corners only on mobile), tap ⌖ to snap back to default, and double-tap/click a legend image to enable zoom (pinch, scroll, or trackpad); double-tap again to reset.
🌋 Volcanoes(sub-layer of Geology) Icelandic volcanoes with type, elevation, and last known eruption date. Click for details. Coordinates have been cross-referenced against the LMÍ örnefni database for accuracy.
🌋 Reykjanes EruptionsAll Reykjanes eruptions 2021–2025 (Geldingadalir, Merardalir, Litli-Hrútur, Sundhnúksgígar 1–9) from LMÍ. Lava flow polygons are colour-ramped by year and accompanied by current hazard zones and eruptive fissures — use the sub-panel to pick which layers you want visible. A scrollable list of every eruption appears below; tap any entry to activate or deactivate just that lava field, and use the Show all / Hide all buttons to flip every field at once. Enabling the master toggle auto-zooms to the eruption area.
📜 Historical (sub-layer of EQ Archive)A curated catalog of major Icelandic earthquakes before the digital SIL seismic network existed (1164 to 1896). Amber circles sized by estimated magnitude (roughly M5.5 to M7.1), with a scrollable list panel that opens automatically. Tap a bubble or list row and the dark popup tells the full story: what happened, who recorded it, casualties, and the scholarly source (mostly Páll Einarsson 1991, Þorvaldur Thoroddsen 1899, the Icelandic Annals, and parish records). Coordinates are best-estimate centroids from damage maps; magnitudes are estimated from felt-area and intensity reports with uncertainty of roughly ±0.5. Includes events like the 1294 "Stórjarðskjálftinn" (the Great Earthquake), the 1784 Suðurland mainshock that destroyed Skálholt cathedral and ended its 740-year run as the bishop's seat, the 1872 Húsavík twin shocks on the Tjörnes Fracture Zone, and the 1896 sequence — five M6+ events in two weeks across South Iceland. Independent of the year scrubbers — can be on at the same time as any archive year.
2D Depth Over TimeThe 2D button on the live Earthquakes panel (and the EQ Archive bar), next to 3D — opens a depth-over-time plot. It opens in All Iceland mode (every quake, no corridor) so nothing jumps off the area you were viewing. Press Select area and tap two points on the map to draw a corridor exactly where you want it — then drag either endpoint to fine-tune. Quakes inside the corridor (adjustable ±1–20 km, default ±15 km) are plotted as time (horizontal, UTC) vs depth (vertical, deeper = lower) — so you can literally watch a dike intrusion climb toward the surface, the classic pre-eruption signal. Dots use the same magnitude colour scale as the map; archive (1992+) quakes get a violet ring; hovering one rings it on the map. The live time slider docks into the bottom of the panel and is the single time control — pick 6 h / 12 h / 24 h / 48 h / week / month or drag the dual handles, and the plot shows exactly that window (archive years use their own scrubber). New: drag a rectangle anywhere on the chart to select a sub-group of quakes — a View 3D button appears in the corner of the chart and opens the new 3D Selection Viewer (below). Pre-instrumental "Historical" quakes are excluded because their depths aren't real. The panel drags and resizes like the other floating windows. Dýpi yfir tíma.
3D Selection Viewer (new — WIP)Opens from inside the 2D Depth Over Time panel. Drag any rectangle across the 2D chart, then click the View 3D chip that pops up in the top-right corner of the chart. A small floating box appears with just the selected quakes rendered in proper 3D — orbit by dragging in the box, zoom with scroll wheel or pinch, with labelled depth tick rings (0 / 1 / 5 / 10 km etc., adapting to how deep the swarm goes). The box is draggable and resizable like the other floating panels. It stays in sync with the time slider — scrub time and the spheres inside come and go in real time while the bounding box and your camera angle stay locked, so you can watch a swarm fill in or thin out over the chosen window.
🕰 EQ ArchiveBrowse historical Icelandic earthquakes year-by-year — the same IMO Skjálftalísa data as the live layer, just pulled from a static cache. Ten years are available: 2025 (Sundhnúkur), 2024 (first Grindavík eruption + evacuation), 2023 (Reykjanes crisis), 2022 (Meradalir), 2021 (Fagradalsfjall), 2014 (Bárðarbunga / Holuhraun), 2010 (Eyjafjallajökull), 2000 (South Iceland M6.5 + Hekla), 1998 (Grímsvötn), and 1996 (Gjálp / Vatnajökull jökulhlaup). Tap the ⓘ on the archive bar to read about that year's notable event. Each year is a separate sub-button under the parent toggle — single-select. When you turn one on the map auto-loads tens of thousands of events and a draggable scrubber bar appears at the bottom: pick a magnitude floor (defaults to M 3+ to keep performance smooth), drag the dual-handle slider across the year, or jump straight to the eruption window with the 48 h or 7 days buttons (which switch the slider to 5-min / 30-min blocks for fine-grained replay). The bar opens centred on each year's signature event. A 3D button on the bar drops you into the same depth-view scene as the live layer (live + archive can stack). A 2D button opens the same Depth Over Time panel as the live layer — including the drag-rectangle View 3D shortcut that opens the new 3D Selection Viewer on whatever sub-cluster you draw. Archive circles share the live magnitude colour scale but get a violet stroke + popup tag so you can tell them apart. Adding more years has zero performance cost when they're not enabled — files are fetched lazily.
