Now that more information is becoming available I have been able to pinpoint the location of the eruption to within a few metres. As best I can make out, it is at latitude 28°36’54″N, longitude 17°52’02″W which is 3.2±0.1 km almost due south of here. (Here being Tacande Observatory which is labelled on Google Maps.)
The view is quite impressive after dark but the volcano has caused no trouble at all for Kevin and me as yet.
The location is very close to this point in Google Maps:
