Pahoehoe: Et hawaiisk uttrykk for basaltisk lava med en myk, bølgelignende
overflate.
En pahoehoe flom rykker framover med en serie av
små boblelignende lavaarmer,
som uavbrutt bryter fram fra den avkjølende hovedflommen. Overflaten
kan variere
voldsomt, og frambringe alle mulige bisarre former, og fremkaller
ofte inntrykk av
lavaskulpturer.
Pahoehoe (pronounced "pah-hoy-hoy" - a Hawaiian term), is
lava that in solidified
form is characterized by a smooth, billowy, or ropy surface. (Tilling,
Heliker, and
Wright, 1987)
Pahoehoe is a Hawaiian term for basaltic lava that has a smooth, hummocky,
or ropy
surface. A pahoehoe flow typically advances as a series of small lobes
and toes that
continually break out from a cooled crust. The surface texture of
pahoehoe flows
varies widely, displaying all kinds of bizarre shapes often referred
to as lava sculpture.
