Belchertown skin not picking up local earthquake

[Tim Tuck]

Hi all,

We've just had a tremor 400km south of us near Sydney and the
Belchertown skin has not picked it up but insists that the latest and
nearest is in Vanuatu 3305km away yesterday!

I've checked my lat/long and that is set correctly and I've checked
https://earthquake.usgs.gov and it has my earthquake.

So... what gives ?

thanks

Tim
