Many thanks to all for providing me with evidence we can consider. I’ve had to make two emails
to keep size under 10MB to make sure everyone’s gateway is big enough to receive the data (red
ones will be in second email).
We won’t have time on 3 Oct for participants to review all their work, but will look to you to
summarise your conclusions as we work through the relevant diagnostic questions proposed by
Davis and Frohlich (1993) to consider if there is evidence that the Newdigate events were
induced.

I’ve written a short report on the earthquake sequence that provided a more complete description
than the powerpoint you circulated. I’m waiting for
to approve this. I hope that I will be able to
send this to you either later today or tomorrow. Will you be able to circulate this please?

Thanks.
I guess we have made a family strong conclusion that the events were unlikely to be
induced. But that conclusion may change, if for example, more information comes to lights at
the workshop next week.

Hi
I've attached our report.
has now approved this.
I'd be grateful if you would circulate to the other attendees.
I'm assuming that these won't be released until after the meeting, just in case new
information comes to light?
