Lengai Activity - Lunar Phase Database

Page history last edited by Frederick Belton 13 years, 9 months ago

Activity and Lunar Events at Ol Doinyo Lengai Tanzania from 1987 - 2005

Compiled by Frederick A. Belton

This database was compiled from a variety of sources, including direct personal observation, reports in the Smithsonian's Global Volcanism Bulletin, trip reports forwarded to me by climbers, photographs taken by pilots and by local guide Burra Gadiye and later analyzed by Celia Nyamweru, and remote thermal sensing data by satellite ( MODLEN algorithm) which has been supplied by Matthieu Kervyn of Belgium. In some cases, periods of no activity have been determined by photographic evidence allowing comparison of the crater floor on different dates. Reports by visitors that indicate an entirely white crater have been extraploted to assume no activity on the prior day, however the rapid whitening of natrocarbonatite lava by rainfall makes it unsafe to extrapolate back more than one day. There is no doubt that some errors exist in this data. It is likely that in some cases of activity reported by pilots or day-climbers, an eruption occurred later on the same day. However, since there are a large number of reliable observations, the errors are unlikely to significantly skew the data.

Activity rating scale:

0: No observed activity, or lava lake with no outflow from vent

1: Low to moderate activity (flows on crater floor or Strombolian explosions)

2: strong activity to major eruption (high volume sustained flows, large fountains, ash explosions)

Due to reports being gathered from a variety of sources, there may be some doubt as to

whether an eruption actually deserved a 1 or a 2 rating. Most of the 2 ratings assigned here are

based on personal observation or photographic evidence of large flows/lapilli deposits.

Act = activity level

Per = number of days to nearest lunar perigee.

Apo = number of days to nearest lunar apogee

Full = number of days to nearest full moon

New = number of days to nearest new moon

Full/New = number of days to nearest full or new moon

A negative number indicates the lunar event came prior to the observation date.

A positive number indicates the lunar event came after the observation date.

"+/- x" indicates the observation date was equidistant in time by x days

from the perigee and apogee or full and new moon.
