Disaster Risk Reduction 2015-2030 , in March 2015 in Sendai,
the International Day for Disaster Risk Reduction has been used to promote one
of the seven global targets put forward: Substantially reduce global disaster mortality by 2030, aiming to lower the
average per 100,000
global mortality rate in the decade 2020–2030 compared to the period 2005–2015;Substantially reduce the number of affected

Windspeed conversions
The Icelandic Meteorological Office uses the SI (Systeme Internationale d´Unites) unit metres per second (m/s) in windspeed measurements. Here you can convert between different units of windspeed.

the eruption drifts to the east. High level of SO2, sulphur dioxide, was
measured at Reyðarfjörður last night around 10:00 o’clock. The highest value
measured were just under 4000 micrograms per cubic meter. These are the highest
values measured in Iceland. High level, 685 micrograms per cubic meter, was also
measured in Egilsstaðir.
Warning was sent via the GSM system to all mobile phones

and vulnerability. The
frequency is estimated locally and the vulnerability is estimated using data from the 1995
avalanches. Under the new regulation, new hazard maps have been prepared for the most
vulnerable villages in Iceland. Hazard zones are delineated using risk levels of 0.2*10-4, 0.7*10-4 and
2*10-4 per year, with risk less than 0.2*10-4 per year considered acceptable.

These observations suggest that a glacial outburst flood (jökulhlaup) is in progress.
It is likely that the flood originates from the western Skaftá ice cauldron, which last drained in June 2015; however this is unconfirmed until visual observations are made. The discharge of Skaftá at Sveinstindur at noon was 112 cubic metres per second.
The flood is not expected to cause any downstream disruption, although

originates from the western Skaftá ice cauldron, which last drained in June 2015; however this is unconfirmed until visual observations are made. The discharge of Skaftá at Sveinstindur is presently 270 cubic metres per second.The flood is not expected to cause any downstream disruption, although the following points should be kept in mind:Hydrogen sulphide is released from the floodwater as it drains

part of Skaftárjökull and Tungnárjökull, where floodwater could burst through the surface.
Background
Floods in Skaftá are sourced from two ice cauldrons, formed due to persistent geothermal activity beneath Vatnajökull ice-cap. On average, the cauldrons drain every two years, producing floods of up to 1,500 cubic metres per second. When the interval between floods is short the flood tends
