Eruption plume:
Height (a.s.l.): Detected by weather radar at 15:20 GMT at an elevation of 2.8 km over
the eruption site. TF-SIF observations at 15:40 GMT confirmed a steam
plume rising to 4.5–5.1 km (15–17,000 ft). Clouds of ash at lower
elevations observed drifting south

). The ice caps are Eyjafjallajo¨kull (ca. 81 km2),
Tindfjallajo¨kull (ca. 15 km2) and Torfajo¨kull (ca. 14 km2). The DEMs were
compiled using aerial photographs from 1979 to 1984, airborne Synthetic
Aperture Radar (SAR) images obtained in 1998 and two image pairs from the
SPOT 5 satellite’s high-resolution stereoscopic (HRS) instrument acquired in
2004. The ice-free part of the accurate DEM from 1998

Vestmannaeyjar, 12 km off the south coast of Iceland. It is surrounded by sea to the east, south and west. The elevation above sea level is 118 m. Distance from the fishing town on the island is 4.5 km, distance to the nearest village on shore is 40 km and distance to the nearest town on shore is 70 km. That town has less than 5000 inhabitants. This is an ideal seashore background station at 63°N, 20°W

caldera. The characteristic activity is explosive basaltic eruptions occurring on central volcano flanks or the
fissure swarm. Known eruptions have mostly been VEI 3-4 but occasionally VEI 5-6 (bulk volume of tephra up
to 10 km3). The largest eruptions occurred in the early Holocene, effusive basaltic eruptions on the fissure swarm
with lava volumes ≥20 km3. Eruption
