Particulate matter (PM) and eruption plume

Recently the level of PM10, particles with a diameter less than 10 mm (10-5 m), has been really high in Vik (~40 km SE of volcano) and surrounding areas. High being daily average of more than 10, and even, 20-times, the recommended health limit (50 mg/m3), and reaching values above 10 000 mg/m3. For comparison values reaching at most 2 000 mg/m3 are reached just after midnight on New year’s eve!

The satellite image below, from today, shows the eruption plume extending above the low clouds surrounding the Eyjafjallajökull volcano (and western part of the country).
