On checking the log today I saw that my VP2 rain gauge had reported a tip at
about the same time as yesterday morning's earthquake. It's only set for 15
minute downloads, so I can't be sure of the exact time (it's reported as
12:45 am which would really be a bit early). The ISS and rain bucket are
together on a steel pole at the 125cm or so recommended height of the
thermometer. There had been no rain the previous day and the 5" copper
gauge was bone dry at 09Z that morning.

Did anyone else get an unexpected tip at that time?
