Isn't there a volcanic eruption happening Iceland right now? I think that one is already out of date.

Seems like their source hasn't updated this

Any seasoned engineer would hardcode the values at the bottom of the page.

Every section has an information button which says where the data is sourced from.

I think the question may have been more about method of updating.

I know the USGS websites have great API support, and I imagine the NASA solar flare reporting does as well, so I expect most of this is automatic.

The ones going to Wikipedia articles must be done by hand, so those will stop being updated when Neal gets bored of updating.
