February 5-7, 1999

Krakatau erupted on February 5, with an explosion that could be heard up to 40 miles (60 km) away. On February 6, smoke from the event rose up to 1000 ft (300 m). Four explosions were heard during the event. On February 7, smoke also reached about 1000 ft (300 m) above the volcano. About 20 explosions were heard during the day's activity.

In early April, R. Sukhyar, spokesman for Indonesia's Mines and Energy Ministry, released a warning for Krakatau volcano. Eruptions of rock and ash are occurring every hour and are considered to be "moderate to not dangerous." Fisherman and tourists are required to stay 5 km from the volcano. Recent eruptions of Krakatau have been at Anak Krakatau, an island that emerged in 1927. One tourist was killed and five more injured by an explosion at Anak Krakatau in 1993.

Anak Krakatau is undergoing relatively quiet periods, lasting at least a couple days, punctuated by periods of nearly continuous eruption. Mike Lyvers visited the volcano on May 17, 1997. Eruptions consist of minor ash emissions, accompanied at times with a few bombs. Lyvers reported that occasional larger explosions sent incandescent ash high into the sky. These larger explosions generated a spectacular displays of volcanic lightning and covered the cone with glowing bombs. No obvious pattern was detected in the intensity of eruption.
