Powerful earthquake rocks Amberly New Zealand.kmz (1.08 KB) Powerful earthquake rocks Amberly New ZealandNew Zealand: 7.8-magnitude quake rocks south, triggers tsunamiA powerful 7.8-magnitude earthquake has rocked New Zealand's South Island, triggering a tsunami as people fled buildings in a panic and were told to seek higher ground. The quake struck around 50 kilometers (around 30 miles) northeast of the city of Christchurch just after midnight local time on Monday, the US Geological Survey reported. Waves of 2.49 meters above usual tide levels were measured near the epicenter by the Pacific Tsunami Warning Center (PTWC). Source

1) Has anyone heard from Norm? Are he and his family OK? Please report if you have any news.
2) Has anyone heard any informed (i.e., scientific) speculation about the effect of the "super moon" in triggering this earthquake?

The text on the CNN website says: "The quake struck some 93 kilometers (55 miles) northeast of the city of Christchurch just after midnight local time on Monday, the US Geological Survey reported. It triggered waves of 2.49 meters above usual tide levels, the Pacific Tsunami Warning Center (PTWC) said."
The video posted on that site gives the distance from Christchurch at about 80 km, and reporting also indicates that aftershocks are appearing mostly northeast of the epicenter, so although the force of the quake is "186 times" greater than the Christchurch quake, maybe that population center has suffered less than the more sparsely populated region to the northeast.

A super moon, as close it will get to the Earth, I would think it could produce tsunami's. Yes! It can cause earthquakes, according to this >> Article <<

A super moon, as close it will get to the Earth, I would think it could produce tsunami's. Yes! It can cause earthquakes, according to this >> Article << Of course the moon's gravity affects earthquakes. But what I meant was, how much does the moon being in extreme perigee increase the gravitational attraction, and can you quantify the increased risk of earthquakes of a "super duper moon" over a regular "super moon" and over "normal" perigee. Earthquakes, volcanic eruptions, and landslides produce tsunamis, all of which can be triggered, I think by gravitational forces, but gravity alone, I think, will not create a tsunami unless the moon gets one heck of a lot closer than it is now, and even then I think I'd call it just a very high tide.
