measurement by walking along the edge of the lava field (Photo: Elísabet
Pálmadóttir).The
gas released from the eruption has been spreading over Iceland in the past 6
months. The area most impacted is northwest of the eruption. Short-lived peaks
in SO2 ground concentration over 1000 microgram/m3 have
been measured in a few instances in Njarðvík (Figure 9) and Vogar for example

Width of fracture line: 800 m
Vertical drop: 350 m
Runout length beyond the lake shore: ~1000 m
Volume: ~30–50 million m³
Estimated duration of the slide: 20 seconds according to seismographs

2004 after finishing the case study. Newspapers were
distributed to 1000 households in the local area.
At the final joint meeting where both groups participated
in March 2004 (step 7), the stakeholder groups were asked
to comment on the involvement process on the basis of
four questions: (1) Is there a need for further initiatives for
the protection of groundwater? (2) How have you
experienced

earthquakes were detected. Three were larger than magnitude 3, the largest M3.3 at 2:37AM located around 1km N of Nátthagi valley. Today at 13:00GMT the Scientific Advisory Board of the Icelandic Civil Protection will meet to evaluate the latest monitoring data. Findings of the meeting are expected shortly after 15:00GMT.Updated 15.03 at 11:00 Since midnight over 1000 earthquakes have been detected

It is not always easy or obvious how to classify the size of an avalanche, however, the destructive potential is the predominant

(not sea level), in ascending order that correspond to the intervals 0-50m, 50-100m, 100-200m,
200-300m, 300-600m, 600-1000m, 1000-1500m, 1500-2000m, 2000-2500m and >2500m and
if the height is between intervals, it’s rounded up. Mountains are typically used to estimate the
height of the clouds, if that’s not possible the type of clouds are studied to estimate the height
