The eruptive activity at Redoubt continues, with three further eruptions logged by the Alaska Volcano Observatory during 28 March 2009:
- 13:40 AKDT (21:20 GMT), eruption cloud top at 25000 feet (7600 metres) above sea level. AVO information.
- 15:29 AKDT (23:29 GMT), eruption cloud top at 35000 feet (10700 metres) above sea level. AVO information.
- 19:23 AKDT (03:23 GMT), eruption cloud top at 45000 feet (13700 metres) above sea level. AVO information.
The 19:23 eruption cloud passed over the Anchorage area and gave the city its first ashfall of this eruption (although trace amounts from earlier eruptions have been found there). The AVO described the ashfall as ‘minor’ and decreasing, but expects it to continue overnight. An ashfall advisory is in effect until 01:00 29 March 2009.
The latest information from the AVO (2009-03-29 00:23:34) is that seismicity has declined, and that ‘Repeating earthquakes started at 23:52 AKDT and are continuing at this time’. These earthquakes are producing an interesting trace on the REF Webicorder:
