New research on Auckland's volcanos

Graham Leonard @grahamleonard.bsky.social · Jul 19

Lots of new research and planning for Auckland Volcanic Field in today's chat with Mihi and Susie @rnzrss.bsky.social @earthscience.nz www.rnz.co.nz/national/pro...

Auckland is known for its volcanic cones - and while an eruption is very unlikely to happen, the volcanic field is technically still active.
