July 2007 Eruption--Quarry flow near-view map: July 22, 2010

Map showing a close-up view of flow field expansion over the past week. Light red (lower left corner) is the extent of the July 2007 eruption flow field. Reddish-brown is the extent of the currently-active Quarry flow as of July 14, 2010, while bright red shows the flow field expansion of the Quarry flow mapped by HVO geologists between July 14 and July 22. Lava erupted while Kupaianaha was active from 1986-1992 is shown in light yellow. The currently active flows are blocked to the south by the north-facing fault that defines the northern edge of the Hakuma horst--a fault block that is raised higher than the surrounding ground. The lava will need to fill in a fairly broad low area along the remaining segments of Hwy 137 before it will be able to top the higher ground of the horst.
