produce runny lava
icalandic eruption
runny lava that floods the Earth’s surface through long cracks
icalandic eruption
Volcanic eruption produce runny lava that floods the Earth’s surface through long cracks called fissures, which can be up to 15 miles long.
icalandic eruption
Volcanic eruptions characterized by numerous fissures
Hawaiian eruptions
Volcanic eruptions characterized by numerous fissures result in large quantities of hot, thin, and runny lava that flows rapidly out of the main vent
Hawaiian eruptions
