Earthquakes around the world

So far, there is no sign the earthquakes are connected to volcanic activity, according to this source

The link does not say that there is no sign of connection to volcanic activity, as it does not mention anything about volcanoes. This might be due to ignorance on behalf of those writing the article or perhaps just to not alarm people. Then again most news services don't try to connect dots for their readers. But volcanic rumblings are increasing on Iceland. As Mkrnhr mentioned on volcano thread:

There is also the possibility of a volcanic eruption in Iceland to happen soon.

Here is a little bit about volcanic activity on Iceland from an article from Electroverse:
The previous eruptions at Reykjanes and Krýsuvík were in the years 1830 (VEI 3) and 1340 (VEI 1), respectively, and because it has been hundreds of year since each of these volcanoes last erupted what exactly happens in the lead-up is unclear; however, what is understood is that earthquake activity always increases sharply before an eruption, and can do so a good while before the first eruption happens, writes icelandgeology.net.

Moving on, Grímsvötn is Iceland’s most frequently erupting volcano, and over the past 800 years some 65 eruptions are known with some certainty.

Grímsvötn Volcano is a subglacial volcano situated near the centre of the Vatnajokull ice cap.

Icelandic scientists have been carefully monitoring Grímsvötn since its 20km (66,000 ft) Plinian eruption in 2011; and recently, researchers have seen various signals that suggest the volcano is getting ready to erupt again, and have raised the threat level accordingly.

Katla is yet another Icelandic volcano on the brink of an eruption, according to the Icelandic Meteorological Office (IMO).

Since January of last year, researchers have recorded an uplift in and around the volcano, and more recently have recorded an increase in sulfur dioxide close to where two previous eruptions have taken place. Katla’s previous sizable eruption was the VEI 4 back in 1918 (volcano.si.edu) — that year falls within the Centennial Minimum, the previous multidecadal spell of low solar activity.

I am confused...

The 4 links you provided to news articles are from two different earthquakes. One from 13 Nov 2016, the other appears to be from Nov 2017, therefore unrelated to the latest Earthquake today, near Gisborne NZ.

Nevertheless, it is for sure that New Zealand is an earthquake prone area... and it is interesting to look at photos from past events.

A preliminary 5.9 M hit Mainland Greece about 5-10 minutes ago but it doesn't appear on that site yet. I can update this post with a link when it's up.

10 years on from Christchurch disaster, powerful earthquakes strike off New Zealand (UPDATES) -- Sott.net

Comment: This keeps happening. In the last couple of years, strong quakes have been occurring on or very close to significant anniversaries (from the point of view of the afflicted country)... Quake centred at 10km depth, about 178km from town of...

You are right. Since Guardian has grouped all of them in place in one page, I thought they are from same one. I need to check of each article of the date, particularly when I check things in hurry( in between office time etc.). Thank you for letting me know.
 
Another big earthquake about 1000 km north of the M7.3 in New Zealand and next to the other one which was 7.4.
This one is a M8.0

M 8.0 - Kermadec Islands region​

  • 2021-03-04 19:28:35 (UTC)
  • 29.600°S 176.000°W
  • 10.0 km depth
Added detail to make it more precise as there has now been 2 M7 and 1 M8 in the last few hours. One 7.3 in New Zealand and two in the Kermadec region, M7.4 and a M8.0.
 
And another, which came just before the other M8.0, but which USGS just listed now. Also next to the other one.

M 7.8 - Kermadec Islands, New Zealand​

  • 2021-03-04 19:28:30 (UTC)
  • 29.747°S 177.224°W
  • 10.0 km depth
Added: It came just 5 seconds before the M8.0. It is rocking and rolling there and it might not be the end of it.

Update 2: USGS now gives this latest one as coming 3 seconds later and not before the 8.0.
 
The last two earthquakes 3 seconds apart have now been classified as just one earthquake and with a magnitude of M8.1

M 8.1 - Kermadec Islands, New Zealand​

  • 2021-03-04 19:28:30 (UTC)
  • 29.729°S 177.262°W
  • 10.0 km depth
