06:00 AM | BY: VN
RVO reported that activity at Manam decreased on 18 April and continued at low levels through 21 April. Roaring noises came from both Main and Southern craters. Both craters were incandescent, but only Southern Crater ejected incandescent tephra, which became intense during 0900-1100 on 20 April.
Pale gray-to-brown plumes with a minor amounts of ash rose from both craters and drifted SE. RSAM values were about 75-150 units, but between about midnight and 0100 on 22 April they began to rise. RSAM values were 600 at 0500, and then they fluctuated between 400 and 1,400 units at least through 1400, the time of the report posting.
According to a news article from 25 April the Alert Level was raised to Stage 3, and an official on the island noted that women and children have begun to be evacuated to Bogia on the mainland.
