The Hawaiian Volcano Observatory, the first volcano observatory in the United States, is located on the west rim of Kīlauea Volcano's summit caldera in Hawai‘i Volcanoes National Park. A volcanic gas plume rises from a vent that opened in 2008 at the base of the south wall of Halema‘uma‘u Crater. Crater Rim Drive in foreground.

Incandescent arcs trace the path of lava fragments cast out during a tephra-jet explosion at the Waikupanaha ocean entry in 2008. This is a relatively small explosion, reaching a few tens of meters (yards) height, while one earlier in the day was nearly 70 meters (230 ft) in height.

When lava from the Pu'u 'Ō'ō-Kupaianaha eruption, active since 1983, meets the ocean, large littoral explosions can result.

The early morning helicopter overflight of the lower East Rift Zone shows lava continuing to enter the sea at Ahalanui. The southern margin of the flow remains about a quarter mile from the boat ramp at Isaac Hale Park (jetty visible in the center left of the photo). View to the northeast.

Photograph of the Donghekou Landslide, triggered by the 2008 Wenchuan, China Earthquake. This landslide had 3 sources areas: the mountain slope at the top right of the photograph a second area primarily resulting in a rockslide that occurred to the left of the scientists, and one to the right, across the river (not shown in picture).

Train tracks and overwater structures along Browns Bay in Edmonds, Washington often occur on developed shorelines of Puget Sound. The built environment can interrupt the flow of sediment from back-beach bluffs to the intertidal zone, attenuate and redirect alongshore currents, and reduce upper beach habitat.
