The elevation varies with volcanic activity. The volcano last erupted 21 May 2023. It is frequently given as 3,350 m (10,990 ft), but many sources that support this concede that this is approximate. The coordinates given, which are consistent with SRTM data, are from a 2005 GPS survey. The elevation data are based on a LIDAR (Light Detection and Ranging) survey carried out in June 2007, see Neri, M.; et al.
