Yasur volcano (Vanuatu), activity update:strong eruptions, ash cloud reaching 1.8 km
mardi juin 01, 2010 08:27 |
Yasur's strong activity is sending ash clouds to up to 1.8 km elevation and causing problems with ash fall in surrounding villages.
Variuous media are talking about "giant ash clouds", that could disrupt flights across the Pacific.
While it's understandeable that the trauma of the Icelandic eruption of Eyafjallajökull volcano in April has news reporters now on high alert about potential ash clouds threatening flights, it is exaggerated to classify Yasur's eruption as "giant" (so far). Local flights to and from Tanna, might very well be affected, but however impressive and violent Yasur's strombolian eruptions might seem for now, an ash cloud reaching mere 2 km has certainly no potential to seriously disrupt international trans-Pacific flights.
No evacuations have been reported, but the access to the crater rim (now frequently hit by bombs) remains closed.

Yasur's activity has continued to be very violent, with explosions that often throw bombs onto the visitor's rim and as far as the parking lot. This caused the Department of Geology, Mines and Water Resources from Port Vila to raise the alert level to 3 (out of 4) on 27 May. [details]

Yasur volcano's activity continues to be dangerously strong. Explosions frequently throw bombs outside the crater onto the rim, the outer flanks and even as far as the ash plane and the parking lot. Alert level remains at 2, as the Department of Geology, Mines and Water Resources from Port Vila stresses in their latest bulletin about Yasur. [details]

During our expedition on Tanna Island, we observed Yasur during 25-29 May. Activity was a low to moderate levels in that period and only 3 vents in the western crater were active although glow from the eastern crater was seen. Near-continuous spattering was seen from the westernmost vent, and more powerful ejections from the other two vents were observed at intervals of 10-15 minutes, throwing incandescent lava bombs to 100-150 m height. Only small amounts of ash were usually produced. ... [details]
