Low-level eruptive activity at Colima, the most active volcano in Mexico, has been causing concern recently. On 26 November 2009 an overflight reported that the lava dome, which began its current phase of growth in February 2007, filled 80% of the summit crater. According to reports of the most recent overflight, which took place on 20 January 2010, the dome now fills 85% of the crater and has reached 65 metres in height. The local civil protection authority, the Unidad Estatal de Protección Civil y Bomberos (UEPCB), reports that there is a risk of dome collapses taking place, particularly in the south-western area of the summit where instability is greatest, but that the current activity of the volcano ‘is not a risk to the surrounding population’. A 7.5-km-radius exclusion zone remains in force around the volcano.
