2. lava flow. Lava flows are masses of magma that pour onto the Earth's surface during an effusive eruption; they include both moving lava and the resulting solidified deposits.. 5. Lava Dome. Lava domes are fascinating geological features that can grow over time as layers of lava accumulate. They often pose potential hazards due to their instability and the potential for explosive eruptions when pressure builds beneath them. When lava is too thick and sticky, it piles up around the vent and forms a dome.

Schematic diagram of lava flow folding (Gregg et al., 1998). Fold Spectum Study: An example of photogrammetric 3D models of pahoehoe lava flows from the SU lava project. Digitized topography of the lava surface can be profiled and analyzed using Fourier transform to reveal a power spectrum of the complexly folded crust. (James Farrell, 2017)
