There has been a small eruption from a remote Alaska volcano.

The Alaska Volcano Observatory says satellite imagery showed a low-level ash cloud from Cleveland Volcano on Sunday.

Officials say the cloud dispersed over several hours as it tracked to the southeast, and there were no reports of it from nearby mariners or pilots.

The alert level for the volcano was raised in June after a brief eruption and a pilot reporting an ash cloud rising to 35,000 feet. There's no real-time monitoring network at the 5,675-foot volcano, which is on an uninhabited island about 940 miles southwest of Anchorage.

The observatory says additional eruptions are still possible with little warning, and ash clouds 20,000 feet above sea level are possible.
