Start your morning with views of #pillowlava
@nautiluslive.org is diving in the Mariana backarc at the Burke vent field ~3700m nautiluslive.org

The rounded, bubbly shapes of these pillow lavas are a clue of quickly cooling rock that formed shortly after erupting underwater. #Pillowlava formation is visible today at #Kama’ehaukanaloa (formerly known as #Lō'ihiSeamount), southwest of the big island of #Hawaii.

Today is #VolcanoThursday during my #hedgewatch'es with my humans on #LaPalma we found not only beautiful #PillowLava (fig1) we also found pillow #breccia (fig2) i.e. broken pillow #lava. MAybe this happend during the large #landslide that formed the #caldera de Taburiente

Today 3D #PillowLava for #VolcanoThursday. Such #lava forms during underwater #eruption's & is often #basaltic. Cold #water causes formation of a skin. Following lava inflates the body until the skin ruptures & forms new pillow's.
