Hi, all,

This may be a silly question, but wouldn't that size of the crater/impact in Peru be captured as an event on a seismograph?

I would suspect there are plenty in this region.
I haven't read the articles over the past two days, so apologies if this information has already been announced.

Cheers,
Pete
