Flowing out of sight

Lava commonly flows from the surface into preexisting cracks and cavities made during earlier periods of flow emplacement and inflation. Generally the lava cools quickly underground against the cool rock and consequently doesn't advance far. Often, however, reheating of the older rock as far as 20-30 m downstream from the active surface flow makes the ground surface too hot to touch and turns the sides of cracks incandescent. In this image, surface lava is flowing underground, into an inflation cave (tube) formed last summer. Site is at the front of the western lobe on the coastal flat, about 1.4 km from the ranger hut at the end of Chain of Craters Road. Flash used to show details of dark inflation feature.

### Map shows lava flows erupted 1983-November, 2002

Map shows lava flows erupted during the 1983-present activity of Puu Oo and Kupaianaha (see large map). Lava from the Mother's Day flow (red flow on west side of flow field) reached the sea at West Highcastle early on July 19, at Wilipea early on July 21, and
