She warned pilots to use caution when flying nearby and to follow the observatorys advisories, but added that the eruptions dont pose any significant threat to people.. We expect additional shallow seismicity and other signs of unrest, such as gas emissions, elevated surface temperatures, and surface deformation to precede any future eruption, if one were to occur. A volcanic cloud rising above Bogoslof volcano during an eruption event on June 23, 2017. Satellite images showed the spectacular eruption that took place Saturday evening, with a plume of ash, steam and gas rising like a mushroom above the blue Pacific waters.
