and deformation
may precede many eruptions this is not always the case and depends on how much
stress has already been released and the strength of the upper crust”, says Michelle.Figure 2. A) GPS data from the station KRI in Krísuvík. The
blue line indicates the beginning of the eartquake swarm (24.02) and the red
line shows the beginning of the eruption (19.03). A rapid deformation was
detected

Figure 5. Spring temperature (April and May) in Stykkishólmur. The red line corresponds to a linear trend of about 0.7°C per century.
The temperature variations in the spring (April and May) are similar in timing to the winter. The 1840s had the warmest spring temperatures in the 19th century corresponding to a minimum extent of sea ice at that time. This was followed by a very

eruptive plume follows the wind direction, and it is therefore safer to watch
the eruption with the wind direction behind you, rather than towards you.In calm/light wind (<5 m/s) gas can

supercomputer can perform 4,000 trillion calculations per second, which is more
than half a million calculations per second for every person on the planet. It
will handle state of the art weather models with more than 6 million lines of
code –the Mars Curiosity Rover was built on 5 million- which will produce high
resolution weather predictions

of precipitation have
been made in recent years. Chiao et al. (2004) used the MM5 model at a 5 km
horizontal resolution to simulate a heavy precipitation event during MAP IOP–
2B. The precipitation was satisfactorily reproduced by the model although the
total amount of precipitation was slightly higher than measured by rain-gauges.
