Satellite image of area around flow front...

Detailed Description

This map uses a satellite image acquired in March 2014 (provided by Digital Globe) as a base to show the area around the front of the June 27th lava flow. The area of the flow on October 3, 2014, at 9:20 AM is shown in pink, while widening and advancement of the flow as mapped on October 6 at 12:15 PM is shown in red. The flow front advanced about 360 m (390 yd) since our October 3, 2014, overflight. This puts the flow front about 1.7 km (1.1 mi) directly upslope from AP‘A‘ā Street. The distance is 1.9 km (1.2 mi) when measured along the path of steepest-descent. The blue line and arrowhead shows the projected path of the flow over the next 10 days (to October 16), based on the steepest-descent path and the average advance rate of 120 m/day (130 yd/day) achieved since October 3. This projection is subject to change because the amount of lava erupted from the June 27th vent, and the advance rate of the resulting lava flow, have been variable. The flow could speed up or slow down; the flow front could stall again, and a new active flow front could start again farther upslope; or the flow could stop altogether.
