Rockfall heard in Notts Pot

[CNCC]

On 20th June 2022, CNCC received an email from a group who, while derigging at the top of Centre Route, heard what sounded like a very substantial rockfall somewhere in Notts Pot. They could not see anything immediately around or below them, suggesting it was a distance away.

We are unclear exactly where this rockfall has occurred, but it may be considerable.

Future visiting groups are asked to take considerable care throughout the entire cave, be extra-observant for signs of recent movement, and report to CNCC (and post here) any observations.

We remind you that a rockfall occurred on the traverse up to Adamson's Route in 2021. This was subsequently cleared. We are not sure if this more recent rockfall could be related, although one would have expected it to sound closer from the top of Centre Route if this was responsible.

Therefore please assume that this collapse could have occurred anywhere in the cave until we have more information, and take appropriate care.

That would be quite a terrifying sound

Could have been an earthquake , nothing on record for the 20th but Ramsgill on 19th and Morcambe on 21st , may be added to the list later .Sometimes happens

I was in Illusion when the quarry blasted once. I can confirm that was indeed a terrifying noise.

Went down Birthday Pot today and did not see any debris. Nothing obvious through the window to the bottom of LH route, nor any sign of additional rockfall down Rubble pot. Could not get a clear view through the duck to the bottom of Fossil Pot but nothing big in the stream.
It must be somewhere else.
