This thermal image shows Pu‘u ‘Ō‘ō (see visual photograph at left for equivalent view). Recently, the southeast and northeast spatter cones have produced small overflows out of the crater, shown clearly here by their warm temperatures. The vent for the Kahauale‘a 2 flow is at the northeast spatter cone, and the lava tube supplying the Kahauale‘a 2 flow is obvious as the line of elevated temperatures extending to the lower right corner of the image.
