is usually easily eroded. If the mass is big enough, the momentum and
speed can become sufficiently large to snatch up bridges, buildings or other
infrastructure and therefore cause large amount of damages.
One of the most infamous hazard caused by lahars occurred after
the eruption in Pinatubo in 1991. https://pubs.usgs.gov/fs/1997/fs114-97/
Another example is the devastating lahar

narrow channel or a magma tunnel.The rate of the magma coming from the ventBasaltic magma can flow tens of kilometers from the eruption
vent and the margin of the lava can go up to 10 km/hour depending on slope.
Usually the transport time is shorter, but if the slope gradient

Same earthquakes are shown on the topographic map as in the 3D above, for easy grasping of facts. The height is exaggerated by factor 5 in order to bring forth the landscape. The dept is also multiplied by 5 in order to distinguish between the earthquakes.

small flashes of lightning in the evening of 4 June. Four lightning
flashes were recorded yesterday morning, 6 June.
Noises: Considerable rumbling was heard at Raufarfell (10 km south of the
crater) in the afternoon of 4 June.
Meltwater: Low discharge from Gígjökull.
Conditions at eruption site: Considerable steam emanates from the big crater and has

this period air quality and ozone measurements were started. The first national network of seismometers
was established. The first steps for snow avalanche observations were started and sea ice monitoring was systemized.
Big steps were taken regarding digital technologies which started by computer processing of hydrological data in
1964.

magnitude of 6.6 if the same energy was released in one big earthquake.
This number might sound small, however it has to be kept in mind that the magnitude scale of earthquakes
is logarithmic. An increase of one magnitude corresponds to an energy increase by a factor of around 30,
i.e. a magnitude 5 earthquake releases around 30 times more energy than a magnitude 4. It is however

Notes
The volcanic eruption in Holuhraun continues with similar rate as last few days.
The subsidence of the Bardarbunga caldera continues with same rate as before.

Big earthquakes are still detected in the Bardarbunga caldera. Since noon yesterday there have been 18
earthquakes bigger the M3,0. The biggest one was measured M5,0 at 17:11 yesterday afternoon. Smaller
earthquakes were detected in north part of the dyke and around the eruption site.
No change was detected in water monitoring that cannot be explained with changing weather
