The north side of the island had been a safe zone. Now the risk map, published July 4th, shows that the previous safe zones are now at risk. The airport at which we spent several hours observing the ongoing eruption, has been covered by a pyroclastic flow.
In August 1997, flows were running down the north and west flanks, and ash plumes were rising 4 - 7 km into the atmosphere. When activity slowed down enough to study the flows, it was found that they were rich in pumice.
