A large eruption of Redoubt volcano occurred
at 09:24 AKDT (17:24 UTC) this morning. National Weather Service reports the cloud height to be at least 65,000 ft above sea level and pilot reports indicated a plume height of 60,000 ft. Since this event, a few smaller events have occurred but these did not generate plumes above about 20,000 feet.
Die genaue Zeit der Eruptionrn kann ich nicht ermitteln anhand dieser So2 Infos.
Aber im oben mittgeteilten Link sind sie genau beschrieben inkl. Höhe der gespuckten Aschewolken.
