Aerial photograph looking NW toward the September 26 volcanic vent. The area of buff-coloured material is some of the volcanic ash deposited after the volcanic eruption. Note the open fissures both to the north and south of the vent. Additional cracks are located to the east (right). Photo Elizabeth Baker, Royal Holloway, University of London.
Photo looking NNW from the central part of the eastern flank of the Dabbahu rift segment. Dabbahu volcano is ~30 km from this site. The steep scarps were formed by many episodes of slip along dipping fault planes; some faults show > 3 m of movement in the September-October episode (Figure 10). The faults displace basaltic lavas (dark rocks) and small pockets of windblown ash and dust (white rocks). Photo by Cindy Ebinger, University of Rochester, USA.
Aerial photo of 0.5 m-wide cracks and faults that formed in September, 2005. These cracks formed above the zone where molten rock rose into the plate, reaching to within approximately 2 kilometres of the surface. Photo by Julie Rowland, University of Auckland.
Volcanic vent that opened September 26, 2006. The vent was about 500 m long. View to the south from the north end of the vent - notice the tunnel at the southern end. Notice the layers of ash that built up over a periods of days around the vent. The rhyolitic rocks in the foreground were blown out of the vent. Photo by Julie Rowland, University of Auckland.
Central section of 60 km-long rift zone that opened south of Dabbahu volcano. NW facing fault with > 3 m offset on eastern flank ~ 30 km south of Dabbahu volcano. The cracks formed in older basalts and softer sedimentary rocks and volcanic ash. Photo by Julie Rowland, University of Auckland.

3D view of satellite radar measurements of how the ground moved in September 2005. Over about 3 weeks, the crust on either side of the rift moved apart by as much as 8 metres, with molten rock filling the crack between the plates. Satellite radar data is from the European Space Agency's Envisat satellite. Figure was prepared by Tim Wright, University of Leeds using Google Earth.
Enhanced Landsat Thematic Mapper image of the Dabbahu rift segment prior to the September 2005 events. These satellite images have been enhanced to show subtle differences in rock type invisible to the naked eye. (Bands 7, 4, 1, decorrelation stretch).

Photo looking N of the explosive vent that opened on September 26 after two days of nearly continuous seismic activity. To the right of the ~60 m-wide vent lies a 200 m-wide, 4 km-long zone of open fissures and normal faults that may mark the subsurface location of the dyke. The fault zone continues to the top of the photo to the right of the small rhyolite centre. Photo Elizabeth Baker, Royal Holloway, University of London.
