Field Data
• An estimate of the peak winds for each
home is provided
• This estimate is divided into 5 categories:
– Less than 120 mph
– 120-129 mph
– 130-139 mph
– 140-149 mph
– Greater than 149 mph
Year Built Categories
• Using the homes year of construction a
series of 4 categories were derived to
evaluate the impact of prevailing
construction practices and building codes.
– Pre 1980
– 1980

was heavy in Akureyri in December.
The
greatest snow depth measured in the country was 130 cm, by
Skeiðsfossvirkjun power plant in the
North
on 23, 24 and 25 December.
The
number of days with snow cover in Akureyri was above normal in
February and March but April was completely without snow which is not
common there. In Reykjavík the days with total snow cover was above
normal in February

after the long propagation path cannot be completely regained
by the instrument removal. Other stations with Lennartz 1 Hz + RD3 instruments are asm, gyg,
hei, kri, sau skh and sol. They are all within 130 km epicentral distance so the low frequencies
are not entirely lost in the instrument. Data from station hla are omitted from the data set.

the last two
decades, in 1994, 1996 and 1999.
The 1994 swarm began on 11 May and lasted until 27 June. Between 120 and 130
earthquakes were located during that period, mostly beneath the northern flank of the
volcano. Dahm and Brandsdóttir (1997) analyzed 15 selected earthquakes from the 1994
swarm which were also recorded on a temporary network. Lacking a velocity model for
