Yo there, I see its been quiet the last few days quake wise, I been in hospital, rushed in by ambulance on Monday night bleeding in the bowel from
operation 10 days prior, all OK now but was pretty frightening.
No internet in there
so was pretty boring.
Bit of catching up to do, maybe tommorrow.
Just had a quick look over whats been discussed last few days,
re the noise before a quake,
we get it from the Mag 4's in Cook Strait, you can sort of sence it before you hear it and its like a train coming, all this before any shaking.
I've always put it down to the pressure in front of the P wave
What does P in P wave stand for ?
I did a job for a guy whose new house was built underground a few years back and we were working on the concrete slab roof and felt a 4.8 from Cook
Strait come through. Afterwards we were talking about earthquakes and he said that being 10ft below ground level they always heard the quakes coming
before there was any shaking, so they had time to brace themselves. Safest place I ever been in, 1ft thick solid reinforced concrete walls built like
a bunker. Warm as toast too.
