be seen on all seismometers around Askja, while the low frequency signal can be seen on broadband seismometers throughout the whole country.
The traveltime of the signal from Mókollar (mko) close to Askja to station Ásbjarnarstaðir (asb) in Borgarfjörður is about 55 s; the distance between both stations is about 220 km. This gives the signal an apparent velocity of around 4 km/s, which

The altitude of the plume is monitored by two weather radars, one located in Keflavík International Airport 220 km from the volcano, and a mobile one currently situated approx. 80 km away from the volcano.
Initially the plume reached approx. 20 km altitude but during
