(1) VOLCANO OBSERVATORY NOTICE FOR AVIATION (VONA)
 (2) Issued:20240818/2033Z
 (3) Volcano:Sheveluch (CAVW #300270)
 (4) Current aviation colour code:ORANGE
 (5) Previous aviation colour code:red
 (6) Source:KVERT
 (7) Notice Number:2024-58
 (8) Volcano Location:N 56 deg 38 min E 161 deg 18 min
 (9) Area:Kamchatka, Russia
(10) Summit Elevation:3283 m (10768.24 ft), the dome elevation ~2500 m (8200 ft)
(11) Volcanic Activity Summary:The explosive eruption of the volcano probably ended, but extrusive eruptions from the two centers near the Karan lava dome (the lava domes 300 years of the RAS and a New) continues. Clouds obscured the volcano at now. Satellite data by KVERT shows a 1900 long ash cloud continues to drift to the east of the volcano, its front part at 19:20 UTS on 18 August was at a distance of more than 2400 km from the volcano. KVERT continues to monitor of the Sheveluch volcano.

An extrusive eruption of Sheveluch volcano continues. The danger of ash explosions up to 10 km (32,800 ft) a.s.l. remains. Ongoing activity could affect international and low-flying aircraft.
(12) Volcanic cloud height:NO ASH CLOUD PRODUSED
(13) Other volcanic cloud information:NO ASH CLOUD PRODUSED
