Ol Doinyo Lengai 2005 Expedition
This year's stay on Lengai from July 19 - August 9 was quite
different from previous visits. After a series of eruptions from
T58C began in the early morning of 21 July and continued through 22
July,
Lengai did not erupt again, with the exception
of one tiny lava emission lasting only a couple of seconds on 26 July.
Prior to
our arrival there had been at least a 12 day period without activity,
according to local reports.
Photographs from May suggest that activity may have been infrequent for
several
months. In spite of our disappointment with the lack of
eruptions, we were excited that the one highly active period occurred
during the full moon/lunar perigee. We wondered if the relatively
infrequent
eruptions might be an indication that the long-term behavior of Lengai
is changing.
Members of the 2005 expedition were James Bell, Adrienne
Dickson, Josh Gordon, and Elizabeth Zbinden.
