When you say 'Katla tremors are normal', yes some are normal. There is little or no activity at Katla at present as the qaukes map shows. Note
however the mini swarm under Eyjafjallajokull continues. By the way tremors are not earthquakes as such. Tremors are usually what is referred to as
harmonic tremors and normally are associated with the movement of magma.
The Eyjafjoll volcano looks very much quieter today and the trmor graphs are way down.
This is the link
to get the map above.
And this is the link
for the tremor graphs. GOD is the closest to Katla and HAU is the
closest to Hekla.
Note that on the map it refers to Eyjafjallajokull and Myrdalsjokull. These are the names of the glaciers(ice caps). Where the quakes are at present
is the crater of Eyjafjoll, which is the name of the volcano. The other dotted line is the Katla caldera. Katla (actually Kotla) is the name of the
volcano of course.
Likewise under the Vatnajokull icecap we have Grimsvotn, Bardabunga, Öraefajökull and Kverkfjöll. To the SW of that is Laki.
Here is the link
for the Vatnajokull area.
Basically this is a very 'busy' area of iceland volcanically since north of Vatnajokull is Askja, and more extending up into the Tjörnes fracture
Iceland is split in half by the mid Altlantic ridge and the two parts move at 1 cm per year away from each other.
By the way Katla is NOT showing as active. I would take anything RSOE says with a pinch of salt. If you want to know about Iceland look at the
icelandic maps not RSOE. If you look at the tremor map you will see that they specifically state that nothing is happening at Katla. When that message
goes away - worry!
Hope that helps!
