Evening Lava Report: Don’t Just Watch the Leading Edge.

The lava flow continues to advance northeastward through private property above Old Government Road (Pahoa Village Road)  Hawaii Volcano Observatory’s 5:52 p.m. report said that the  leading edge of the flow had moved about 136 yards in the past 24 hours,  and  had advanced through the afternoon at about 11 yards per hour.  Civil Defense’s 5:30 p.m. report estimated the rate of advance at  5-10 yards per hour.

HVO estimated that as of 4:15 pm,  the flow was about 202 yards in a straight line distance from P?hoa Village Road and about 850 yards  from Highway 130.

Two small breakouts  small breakouts on the north side of the flow that have advanced  about 75 to 120 yards in the past day, broadening the overall flow, which remains only about 55 yards across at its leading edge.  The overall shape of the flow is much broader further upslope, due in part to cumulative breakouts; just because a house was missed by the initial flow doesn’t mean it’s out of danger.

From Hawaii Volcano Observatory: “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 28, 2014, at 1:00 PM is shown in pink, while widening and advancement of the flow as mapped on October 29 at 11:30 AM is shown in red. The dotted blue lines show steepest-descent paths in the area, calculated from a 1983 digital elevation model.”
