Quake map

We live about 20km due West of Napier on the central East coast of New Zealand’s North Island, a world famous wine-growing region called Hawke’s Bay - roughly where the red dot is on this handy ‘recent earthquakes’ map ...

ZL sits astride the junction of two tectonic plates and hence has some fabulous volcanoes, active geothermal areas and, as you can see, numerous earthquakes.  The city of Napier was flattened by a severe quake in the 1930s and almost totally rebuilt in the extant Art Deco style, much of which remains today.  A similarly powerful quake occurred in July 2009 just off South Island, moving ZL about 30 cms closer to VK!  You can easily make out three major SW/NE fault lines running through North Island on the map, while South Island is basically a mountain range thrown up by the colliding tectonics.

Our latitude 39o30’22” (=39.5061o) South by longitude 176o38’48” (=176.6466o) East puts us in Maidenhead locator square RF80HL .

 

 

 

Here’s the satellite image of our place on Google Earth:

Most of forest

Our place is the clearing that looks a bit like a giant telephone in the forest.  The wiggly phone lead going SSE to the edge of the forest is half of our track to the Taihape road - there’s another 2km across the open paddocks.  The straighter strip going SSW from our plot shows the route of a 10kV overhead power line through the forest, feeding just our house.  The white spots in our plot are the house and shed.  The raceway track to the SE of us is a landing strip that is used for the start and finish of an annual motorbike endurance race through the forest (nutters!).

A close up ‘perspective’ view lacks enough definition to see the tower and beam but at least gives a hint of why I get out so well via long path into Europe (SE from here):

House and paddocks perspective

The slope is exaggerated in that view but we really are on a N/S ridge and the paddock to the SE is hard to walk up without holding on to the fence.

Here’s our house, “Castle Peak”, photographed with a long telephoto lens from a little hill way across the valley to the SE ...

The 20 acre plot means plenty of space for antennas, though I could really have done with that passing helicopter to put some strong lines over the tall old pine trees behind the property.  That’s a 12m tower in the photo so I estimate them to be about 25-30m (~100 feet) high.

Helloooo down there!

The tower is not as bent as it appears in this shot!  It’s an optical illusion caused by the ladder and perspective.  The fishing pole lashed to a telegraph pole next to the tower is my 40m quarter wave vertical.  With only a few radials laid out, it sort of works.

This hilltop QTH has a good low-angle takeoff in all directions.  We can see the clear blue Pacific ocean in Hawke’s Bay about 15km to our East.  I’d like to show you the takeoff but I haven’t found a decent terrain-mapping program yet that works with available ZL terrain data.  I’m struggling even to find topographical maps showing contour lines in ZL  :-( 

Best I can do for now is this great circle map circled on Castle Peak, drawn using the neat freeware program from SM3GSJ and a hand-modified list of prefixes, trimmed down to leave just a few common and readable ones:

Our Antipodes are EA and CT so naturally they appear right around the periphery of the map and it doesn’t seem to matter much which way I beam for them.  The short path to EU flies right over JA and tends to be dominated by JAs, so LP openings to EU can be more productive for DX, although sometimes I enjoy working JA pileups as well.

The red circle on the great circle map shows the edge of our hemisphere: everything outside the circle is on the Far Side of the Earth from us.  An even more dramatic image (courtesy of Bill ZL3NB) shows how our side of the globe might look from space:

ZL hemisphere 740

Oh boy, what a lot of water!  There are very few hams on our side of the globe apart from ZL, VK, YB, DU, KH6, the Southern tip of CE and LU, and JA disappearing over the edge.  The Americas and Asia are 10-15,000 km away while Europe and Africa are 15-20,000 km away, all of them on the Far Side.  Few of those little specks in the Pacific have active hams.  In other words, almost all of our QSOs qualify as DX.  This makes it tough going for Oceania hams to reach the top of various DX leagues, the DX  Marathon or the DXCC Honor Roll, but it doesn’t stop us trying!
