Did you know lava could move this fast? Neither did we...

Filmed during Kilauea’s eruption in 2018...


  1. Row, row, row your boat
    Gently down the stream...

  2. It's only going 13 mph.

    Reasoning: That mailbox on the right side of the road is unique and must be the one-&-only such right-side-of-the-road mailbox, that is, the one for "13-852 Leilani Avenue" (Plug that into Google Earth, henceforth "GE," or view it in Google's street view), 90 yards east of Leilani & Makamae St. (The telephone poles on the left checkout, as does the Stripe down the middle-of-the-road.) The fact that this was listed as "Leilani Blvd and Pomaikai," 0.86 miles west of here, just means that it was taken through a telephoto lens. As such, longitudinal distances will be shortened A LOT, but transverse ones won't, or hardly at all. This means that the 18-foot-wide width of the road (measured in GE) is an accurate measure, only slightly wider than it would be, if it were superimposed directly upon the flow, higher up, on the screen. That means that the flow that is visible on the screen, is about 40 feet wide, and it takes about 2 seconds for a piece of lava to enter and exit the screen, which is 40 ft / 2 sec = 20 ft / sec. = 13.6 mph.
