Marching On Together


Marching On Together I have had a romance with a lady since my childhood just like thousands of other people around the world who are also in love with her. I have remained in love with her through the many bad times and the few good times, my love for her has never faltered and never will. My lady's name is Leeds United and she is just five games away from returning to the English Football Premiership, after sixteen years in the football wilderness. In the sixties, seventies and early nineties my lady was known as "Super Leeds," however in 2003, my love was relegated from the English Football Premiership due to financial miss-handling by her owners. "Super Leeds," dropped down to the third tier of English football. If Leeds United can grab ten points from their last five games my lady will be back where she belongs in the higher echelons of English football and I can once more embrace my love with happiness.

A magnitude 6.0 - 164km WNW of Hihifo, Tonga is the 3rd major quake of December and the 134th of 2019.

According to USGS, The eastern margin of the Australia plate is one of the most seismically active areas of the world due to high rates of convergence between the Australia and Pacific plates. In the region of New Zealand, the 3000 km long Australia-Pacific plate boundary extends from south of Macquarie Island to the southern Kermadec Island chain. It includes an oceanic transform (the Macquarie Ridge), two oppositely verging subduction zones (Puysegur and Hikurangi), and a transpressive continental transform, the Alpine Fault through South Island, New Zealand.
Since 1900 there have been 15 M7.5+ earthquakes recorded near New Zealand. Nine of these, and the four largest occurred along or near the Macquarie Ridge, including the 1989 M8.2 event on the ridge itself, and the 2004 M8.1 event 200 km to the west of the plate boundary, reflecting intraplate deformation. The largest recorded earthquake in New Zealand itself was the 1931 M7.8 Hawke's Bay earthquake, which killed 256 people. The last M7.5+ earthquake along the Alpine Fault was 170 years ago; studies of the faults' strain accumulation suggest that similar events are likely to occur again.
North of New Zealand, the Australia-Pacific boundary stretches east of Tonga and Fiji to 250 km south of Samoa. For 2,200 km the trench is approximately linear and includes two segments where old (>120 Myr) Pacific oceanic lithosphere rapidly subducts westward (Kermadec and Tonga). At the northern end of the Tonga trench, the boundary curves sharply westward and changes along a 700 km-long segment from trench-normal subduction, to oblique subduction, to a left lateral transform-like structure.
