|Start:||February 3, 2017 ||Observed|
|Lava dome: ||
AVO raised the Aviation Color Code and Volcanic Alert Level at Cleveland on February 3, 3017, following satellite observations of a new lava dome growing within the summit crater. On Feburary 3, the lava dome was approximately 70 m (230 ft) in diameter.
On March 8, 2017, citing no new growth of the lava dome, AVO lowered the Aviation Color Code and Volcanic Alert Level at Cleveland back to YELLOW/ ADVISORY.
A small explosion was detected at Cleveland at 08:15 AKST, March 24, 2017 in both seismic and infrasound data. As a result, AVO increased the Aviation Color Code and Volcanic Alert Level to ORANGE/WATCH. The event was short-lived. Cloud cover obscured satellite views of the volcano. Following this explosion, no further volcanic activity was detected, and AVO lowered the levels to YELLOW/ADVISORY on April 4, 2017.
A new lava dome began growing in the summit crater in April, 2017. Slightly elevated surface temperatures were observed in satellite data, and the first visual indications of a new dome were recorded on April 15 with the presence of a less than 10-m-diameter lava dome. By April 23, the dome has grown to 45 m in diameter. Dome growth occurred with no obvious detectable seismicity. On April 24, AVO raised the Aviation Color Code and Volcanic Alert Level to ORANGE/WATCH.
Another explosion occurred at Cleveland at 7:17 pm May 16, 2017 AKST (03:17 UTC May 17) and was initially detected by seismic and infrasound sensors.
