During 27 March-1 April,
increased seismic activity was recorded at the Krakatau volcano. The seismographs
detected seven deep volcanic, 54 shallow volcanic, and seven tectonic earthquakes.
Krakatau remains at alert level 2.

The Krakatau volcano had an increase in activity during the week of 12-18 March. Type B shallow volcanic earthquakes rose to 79 from only 25 during the previous week. During 19-26 March, the activity decreased again. The volcano is now at hazard level 2 (on a scale of 1-4).

On 29 May, an explosion earthquake was recorded at the Anak Krakatau Volcano. Ash clouds have been 400-500 m high and are accompanied by deep and shallow volcanic earthquakes. The Alert Level at Anak Krakatau remains at 2. Eruptions are still continuing as of 9 June.

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.

Descriptions of recent activity at Anak Krakatau are given on the Global Volcanism homepage.
More than 36,000 people were killed by the 1883 eruption of Krakatau, making it one of the deadliest volcanic disasters in historic time.
