Best guess they are only letting Big Island residents read free. That is common to select what people can see based on location.

Wow. That 3rd picture is like creeping hell.

Here's the HVO map for Saturday 10/25 Note the unexpected change in direction away from the steepest descent line, as described below.

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 24, 2014, at 12:10 PM is shown in pink, while widening and advancement of the flow as mapped on October 25 at 5:00 PM is shown in red. The dotted blue lines show the pertinent steepest-descent paths, calculated from a 1983 digital elevation model (DEM).

The flow advanced about 315 m (345 yd) during the past 29 hours, crossing Apaʻa Street/Cemetery Road at about 3:50 AM this morning, and was about 80 m (260 ft) from the Pāhoa Cemetery at 5 PM. The flow was deflected away from the steepest-descent line it had been generally following, and toward the cemetery, by an old man-made cane-field berm just above Apaʻa Street. The flow is advancing downslope between two intersecting steepest-descent paths and will likely return to the original steepest-descent path about 300 m (330 yd) upslope from Pāhoa Village Road, if it continues.

Steepest-descent path analysis is based on the assumption that the DEM perfectly represents the earth's surface. DEMs, however, are not perfect, so the dotted blue lines can be used to infer only approximate flow paths. For calculation details, see Lava Flow Hazard Assessment, as of August 2007, for Kilauea East Rift Zone Eruptions, Hawai'i Island.

"The flow was deflected away from the steepest-descent line it had been generally following, and toward the cemetery, by an old man-made cane-field berm just above Apaʻa Street."

If not for the man-made berm, it might've missed the cemetery: maybe it will miss. May those that lie there do so in peace near Madame Pele.

Civil Defense alert for Sunday 10/26 - Lava has reached the cemetery and is entering the grounds.

Eruption Information Update For Sunday October 26th At 7:45AM

This is an eruption and lava flow Information Update for Sunday October 26th at 7:45am

The flow continues to remain active and has advanced approximately 250 yards since yesterday morning. The flow front is currently entering the cemetery grounds and advancing at approximately 10 yards per hour in a northeast direction. Smoke conditions were light to moderate with moderate trade winds from the northeast pushing the smoke in a south southwest direction. Smoke conditions may increase in some areas and residents down wind that may be sensitive or have respiratory problems are advised to take necessary precautions and to remain indoors.

Based on the current flow location, direction and advancement, residents in the flow path will be placed on an evacuation notice.

The evacuation notice means residents in the flow path areas should prepare for possible evacuation in the next three to five days. Those area residents will be kept informed of the flow movement and are asked to complete all necessary preparations for a possible evacuation by Tuesday October 28th.

Apa’a Street and Cemetery Road will remain closed and limited to area residents only. In addition, Civil Defense and public safety personnel will be operating in the area round the clock to maintain close observations of flow activity.

Additional updates will be broadcasted as conditions change.

Thanks for keeping this thread updated OpenD. I wish it would let me give you another rep point!

Civil Defense, second alert for Sunday 10/26 - The lava front has already moved through the cemetery. Refer back to the map in Post #244 to get a sense of how quickly the lava is moving.

Eruption Information Update For Sunday October 26th At 3:00PM

This is an eruption and lava flow Information Update for Sunday October 26th at 3:00pm.

The flow continues to remain active and has advanced approximately 95 yards since 6:30 this morning.

[/b]June 27th Lava Flow Observations: Glow from the June 27th flow was visible overnight via webcam, indicating that the flow remains active near its front and mid-way along its length. A Civil Defense overflight yesterday morning found no significant flow advancement, and the distal tip of the flow was still about 1.3 km (0.8 miles) from Apaʻa St/Cemetery Rd, as measured along the steepest-descent line that the flow has been following.
--------------------------------------
Even the daily statement has shrunk in size as the lava flow advancement has seemingly stopped.
While the USGS won't stop the daily updates (they have been doing them for over 20 years!), I assume the Hawaii County Civil Defense will either slow down to weekly updates or pause until the need increases again.

Isn't it remarkable how much can change in only a few days, just as the experts warned us it could? Now a week later they've started evacuations. This is exactly why I didn't stop posting these alerts, so the CDF readers in distant places could stay informed about what is happening.
