Just Like the Old Days

Saturday, October 28th, 2006

October’s equinoxial gales have transported me back about 10 years to the mid 90s when I could sit at the back door and watch the newly planted vege garden heading north under the tender ministrations of a southerly gale. If I had been more quick-witted, I could’ve grabbed some of the plants back a couple of days later as they hurtled by on their way to the South Pole in a northerly gale.


Strong Earthquake, Vanuatu

Thursday, October 19th, 2006

A strong earthquake struck off the coast of the island of Espiritu Santo, Vanuatu, just before midnight.

The magnitude 6.2 earthquake struck at 11:46 p.m. New Zealand Daylight Saving Time on October 18th at a location further north of the previous day’s magnitude 5.2 event.

Tonight’s quake was centred 50 km NNE of Luganville, Espiritu Santo; 315 km NNW of Port Vila, Efate, Vanuatu at a depth of 140 km.

Despite the quake being an undersea event, a tsunami bulletin has not been issued probably owing to the earthquake’s depth.
