Is Ruby erupting right now?
There is no open NASA EONET event for Ruby right now. NOAA NCEI dates its most recent eruption to 1900–1963. 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 Ruby
USGS has no earthquake within 50 km of Ruby 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 Ruby
Ruby is a submarine volcano in Mariana Is-C Pacific, United States, rising to -174 m (-571 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.
The volcano is remote: the nearest city in our list is Uruma, 2190 km away.
Flights and volcanic ash
No major hub airport is within 400 km (the closest is Haneda, 2291 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.
Other volcanoes in United States
United States has 58 volcanoes on this site that erupted since 1900 or are active now, 2 of them with an open NASA activity report today. The closest other one is East Diamante, 38 km away.
