There is a double pulse cycle, or fluctuation, one takes hours and the other
takes between 10 and 20 seconds.

earthquake activity north of GrindavíkRecent data show
that uplift has started again, with the center just west of Mt. Thorbjorn.
Uplift was measured from 22. January 2020 until beginning of February and has
started up again during the first half of March. During the first sequence in
January-February, the deformation rate was about 3-4 mm per day with a total of
a 6 cm uplift during the whole

We have estimated the current economic value of 17 ecosystem services for 16 biomes, based on published studies and a few original calculations. For the entire biosphere, the value (most of which is outside the market) is estimated

During 2003, IICWG and ETSI experts proceeded with editing and testing the standard,
which in its final version includes two separate colour codes with options for use on ice charts:
1) one based on total concentration (CT) intended for use when the stage of development is
relatively uniform but concentration is highly variable (e.g
