Fourth day of the eruption from the Grimsvötn volcano, Iceland.

The morning reconnaissance flight around Grimsvötn volcano showed that the
intensity of the eruption has decreased substantially.
A continuous plume of white steam is seen rising from the crater. Bursts of
phreatomagmatic explosions occurred with intervals. The explosions were
sending jets of ash and fragmented ice approx. 1km up in the air. The
buoyancy of the ash and steam column additionally lifted the plume up to a
height of approx. 4km.

Today the ash fall was limited extending approx. 5km downwind in a southerly
direction.

In cauldrons in the eastern part of the Grimsvötn caldera melt water could
be seen flowing in an easterly direction out of the caldera (see map of the
Grimsvötn Caldera at the homepage of Prof. Magnus Tumi Gudmundsson).

"Why of course the people don't want war. But after all, it is the
leaders of the country who determine the policy, and it is always a
simple matter to drag the people along, whether it is a democracy, or
a fascist dictatorship, Voice or no voice, the people can always be
brought to the bidding of the leaders. That is easy. All you have to
do is to tell them that they are being attacked, and denounce the
pacifists for lack of patriotism and exposing the country to danger."

-Herman Goering,
Hiltler's designated successor
