Ol Doinyo Lengai, Tanzania

According to Frederick Belton’s website, visitors whom climbed Ol Doinyo Lengai on 18 June reported that the new active cone covered the former crater floor entirely except for an area N of the summit. The new cone’s W, N, and E sides stood about 30 m above the rim of the former crater and enclosed a deep crater. The visitors saw a few small vents on the crater’s floor. Frequent emissions of ash-poor plumes originated from the SW part of the crater’s floor, producing light ashfall. They heard continuous loud rumbling noises, occasional gas-jetting sounds, and rockfalls.
