To add to the complexity, there are two main types of lava, which behave quite differently, and researchers never know which type will appear where. Pahoehoe lava flows easily and tends to spread ...

MAUNA LOA, Hawaii (KHON2) — The volcanoes here in Hawaii are basaltic volcanoes, and they create two kinds of lava: A’a and Pahoehoe. Both are made of the same thing–minerals and dissolved ...

Raufarhólshellir Lava Tunnel is a terrific example of a lava cave created following a volcanic eruption thousands of years ago. The Raufarhólshellir Lava Tunnel near Reykjavik in Iceland.

Watching the pahoehoe lava ooze out (from a reasonably safe distance) is fascinating, and surely part of the draw. "Being at the margins of a pahoehoe flow I always find it compelling to take ...

The result resembles pahoehoe lava flows on Earth. USGS geologists at the Hawaiian Volcano Observatory (HVO) get fresh lava samples as close to the Kīlauea volcano vent as possible. Public Domain ...

Pahoehoe lava is usually emitted from the volcanoes in Hawaii. "We performed experiments in a vacuum chamber to simulate the release of mud on Mars. This is of interest because we see many flow ...

“Instead, the experimental mud flows propagate like terrestrial pahoehoe lava flows, with liquid mud spilling from ruptures in the frozen crust and then refreezing to form a new flow lob ...

The results came as a surprise. "Under the low atmospheric pressure of Mars, the mud flows behave in much the same way as ''pahoehoe'', or ''ropy'', lava, which is familiar from large volcanoes on ...

Under Martian conditions, the experimental mud flows formed similar shapes to "pahoehoe" lava frequently occurring on Hawaii or Iceland on Earth, which cools down to form smooth undulating surfaces.

GIFs are a fun and often humorous way to interact via text. A GIF keyboard is automatically built into any iPhone running iOS 10 or later, allowing you to send pictures to convey thoughts or ideas ...

Tubes form by crusting over of lava channels and pahoehoe flows. Kaumana Caves Park near Hilo is a destination for hikers that can explore the lava tubes created by an 1881 flow from Mauna Loa.
