I received via SMS from EWN tonight, even though I am in Adelaide at the moment they don't know that. Watching Sky News it has been caused by a 7.9 earthquake off southern New Zealand that had tirggered a confirmed Tsunami, even though it seems to have been fairly mild in it's effects anywhere. The Lord Howe Island advice is a bit more scary than that issued for the rest of NSW.

TSUNAMI WARNING NUMBER 3 FOR LORD HOWE ISLAND
Issued by the Joint Australian Tsunami Warning Centre [JATWC] at
10:45 PM EST on Wednesday 15 July 2009

********************************************************************************

TSUNAMI THREAT TO LOW-LYING COASTAL AREAS AND THE MARINE ENVIRONMENT

********************************************************************************
SUMMARY:

Tsunami warning for LORD HOWE ISLAND.


TSUNAMI THREAT TO LOW-LYING COASTAL AREAS
A threat of MAJOR LAND INUNDATION, FLOODING, DANGEROUS WAVES AND STRONG OCEAN
CURRENTS exists for several hours from 09:30 pm [EST] Wednesday.

COMMUNITY RESPONSE ADVICE FROM THE NSW STATE EMERGENCY SERVICE:

- The NSW STATE EMERGENCY SERVICE has ordered the evacuation of low-lying parts
of coastal towns and villages.

- People are strongly advised to go to higher ground, at least ten metres
above sea level, or if possible move at least one kilometre away from all
beaches and the water's edge of harbours and coastal estuaries.

- Take only essential items that you can carry including important papers,
family photographs and medical needs.

- It may be in your own interests to walk to safety if possible to avoid
traffic jams.

- If you cannot leave the area take shelter in the upper storey of a sturdy
brick or concrete multi-storey building.

- Boats in harbours, estuaries or shallow coastal water should return to
shore. Secure your boat and move away from the waterfront.

- Vessels already at sea should stay offshore in deep water until further
advised.

- Do not go to the coast to watch the tsunami, as there is the possibility of
dangerous, localised land inundation of the immediate foreshore.

- Check that your neighbours have received this advice.

CAUTION:
Tsunami waves are more powerful than the same size beach waves, with the first
wave not necessarily being the largest.

Low-level effects may be observed in neighbouring coastal areas. People are
advised to take care.

They happen quite often, but depending upon their location the threat may be downgraded and the warning is cancelled after a very short time, so you may end up missing most of them. I keep a very close eye on them and there is a lot happening and they seem to be intensifying on the richter scale lately.
I believe the earth is having a bit of a shift and plate movement. 2 good sites http://earthquake.usgs.gov/eqcenter/recenteqsww/   and  http://www.ga.gov.au/bin/listQuakes

here is some of the data of the quake and after shocks

At this point there is only a 177 quakes but that will rise over the next week to over 200+, last year I kept records of  465 quakes in 7 day period.
