How big are they?

Why doesn't the article mention anything about this most important quality? It says that they're "several meters" under ground and that humans and other living things could live there, but are those tunnels like 2 m tall, 100 m tall, or what? GMRE (talk) 14:46, 13 April 2014 (UTC)Reply

It's a good point, I added the width-depth reported on the recently discovered skylight, looks like it's over 100 metres (330 ft) across. This is quite a bit bigger than the only lava tube I have first-hand experience with, Ape Cave which is maybe 10–20 meters. — Brianhe (talk) 16:15, 13 April 2014 (UTC)Reply
