|(1) VOLCANO OBSERVATORY NOTICE FOR AVIATION (VONA)|
|(3) Volcano:||Cleveland (VNUM #311240)|
|(4) Current Color Code:||ORANGE|
|(5) Previous Color Code:||YELLOW|
|(6) Source:||Alaska Volcano Observatory|
|(7) Notice Number:||2019/A53|
|(8) Volcano Location:||N 52 deg 49 min W 169 deg 56 min|
|(10) Summit Elevation:||5676 ft (1730 m)|
|(11) Volcanic Activity Summary:||Satellite data show that starting around 12 January, a new and growing lava dome is present in Cleveland's summit crater. Thus, AVO is raising the Aviation Color Code to ORANGE and the Volcano Alert Level to WATCH.
The presence of the lava dome may increase the likelihood of explosive activity at the volcano. Explosions at Cleveland usually occur without warning and typically produce relatively small volcanic ash clouds that dissipate within hours; however, more significant ash emissions are possible.
|(12) Volcanic cloud height:||None|
|(13) Other volcanic cloud information:||n/a|
|(14) Remarks:||Cleveland volcano is monitored by only one seismic station, which restricts AVO's ability to detect precursory unrest that may lead to an explosive eruption. Rapid detection of an ash-producing eruption may be possible using a combination of seismic, infrasound, lightning, and satellite data.|
