<p>Vent and cinder code from Kilauea Iki's 1959 fire fountain eruption, 1600-1900 feet high. Note light colored foot trail from middle to right edge, near bottom of image.
</p><p>The trail has been closed with the recent eruptions, but I highly recommend it once the Park Service says its safe. 
</p><p>Earthquakes associated with recent eruptions and slumping of the main Kilauea caldera appear to have caused this pile of cinders to slump on its left side.
</p><p>Here's a Park Service film about the 1959 eruption and outflow to the ocean:

</p><p>I hiked this trail in early 1990s - 93, 94? with Ted. We started by going down a long stair cut into the crater wall well off to the left, then followed the light-colored trail visible in the lower part of this frame.

The frozen lave lake surface is heaved and fissured, and steam and sulfur gas come out in various places. It looks all together like a freeway or shopping mall parking lot shed its skin.
