Lava ocean entry at Waikupanaha, west of Kalapana, Hawai'i. Streaks are from basaltic bombs being propelled tens of metres into the air. Flowing red lava is just visible through the acidic steam plume. The brown lobate structures visible underwater are accumulations of "pillow lava", a common feature of sub-aqueous extrusion of basaltic lavas. The colour of the ocean is due to suspended volcanic glass fragments and thermophilic zooplankton (water temperature at point of entry is about 70 °C). Helicopter doors off, altitude approximately 160 m.

Lobes of pāhoehoe lava inundating the Kalapana access road about 180 m west of the lava viewing trailhead, Kalapana, Hawai'i. Helicopter doors off, altitude approximately 160 m. A number of tourists can be seen viewing the edge of the active flow, unaware of methane explosions occurring nearby (white cloud near shrub left of centre). Viewing was suspended the following day after some people were injured by these explosions soon after I captured this image.

Solidified sulphur "lava" flow on the north-west flank of Lastarria volcano, Atacama Plateau, Central Andes, Chile. Sulphur lava flows are extremely rare on Earth but can provide suitable research analogues for volcanism on Jupiter's moon Io.

An isolated stack of polylithic breccias locally known as "El Cinchado" with the stratovolcano Teide (3718 m) in the distance, Roques de Garcia, Las Cañadas caldera, Tenerife, Canary Islands. The poorly-sorted, matrix-supported breccias are debris avalanche deposits associated with gravitational collapse of the caldera.

Active fissure zone, Krafla, Iceland. Between 1975 and 1984 this area was the site of major fissure eruptions and spectacular “fire-fountaining”. Although effusive activity had ceased by 1988, it was still a challenging terrain to traverse let alone conduct geophysical fieldwork. The very fresh vesicular basalt was both razor-sharp and unstable, and the air was thick with hydrogen sulphide. The painting attempts to convey the scene as I experienced it.
