Is Unnamed erupting right now?
There is no open NASA EONET event for Unnamed right now. NOAA NCEI dates its most recent eruption to 1964 or later. Volcano observatories can raise alert levels before an eruption starts, so check the national observatory for the current alert level.
No satellite thermal hot spot was detected within 10 km of the summit in the latest NASA FIRMS data, so there is no sign of lava at the surface large enough for VIIRS to see (clouds can hide it).
Earthquakes near Unnamed
USGS has no earthquake within 50 km of Unnamed in the past 30 days. Outside the United States USGS mainly lists quakes above about M4, so small volcanic tremors recorded by the local observatory will not appear here.
About Unnamed
Unnamed is a submarine volcano in Tonga-SW Pacific, Tonga, rising to -40 m (-131 ft). NOAA NCEI classes its eruptive history as "Historical".
Submarine volcanoes erupt under the sea; shallow ones can produce steam explosions, pumice rafts and discoloured water.

Flights and volcanic ash
No major hub airport is within 400 km (the closest is Auckland, 2332 km away), but ash clouds from explosive eruptions can drift for thousands of kilometres along flight routes.
Volcanic Ash Advisory Centres (VAACs) issue the official ash advisories that airlines and air traffic control follow.
