The Ulawun volcano erupted just after 09 UTC on 03 August 2019 — retrieved Volcanic Ash Height images from the NOAA/CIMSS Volcanic Cloud Monitoring site (above) showed values generally in the 16-18 km range, with some portions of the umbrella cloud as high as 18-20 km. An advisory issued by the Darwin VAAC estimated the maximum volcanic ash height to be 63,000 feet or 19.2 km.

Volcanic Ash Loading and Effective Radius products (below) indicated that there were high amounts of large ash particles within the volcanic cloud as it drifted southwestward.
