and
around
it. The estimated height is
below 5
km since
clouds over the glacier
were at 5-7
km and the plume did not reach
above the
cloud deck.
The
ash plume reached
8 km briefly at 14 UTC today, but decreased
shortly there
after.
According to pilot reports the plume is visible at
around 10 thousand feet, mostly light gray or
brown in
color, but
pulsating to 15 thousand feet
