Are Two New Zealand Earthquakes a PM Alert from @StevieNZ?

  • Thread starter davenn

In summary, a 5.1 magnitude earthquake occurred in central Cook Str, which was not recorded due to a more powerful one from the South Island. The USGS recorded the South Island earthquake as a 6.1 magnitude. The year has been relatively quiet in terms of earthquakes, with only four M7.0 to 7.9 events compared to the average of 12. The recent earthquake in Mexico City on the anniversary of the 1985 quake serves as a reminder of the devastation that can occur. However, Earth seems to be attempting to rid itself of the human population.

from a PM alert to me from @StevieNZ

http://www.geonet.org.nz/earthquake/2017p708412 - felt that a few mins ago

yup well that one was central Cook Str. 5.1 is a respectable event :)
I didn't record it or the signal was lost in the overpowering one from S of the South Island
which the USGS put at 6.1

Odd, because https://www.stuff.co.nz/national/nz-earthquake/97046815/earthquake-hits-south-of-invercargill earlier before

I recorded it quite well
the bottom event on the trace

https://www.physicsforums.com/attachments/zhi-gif.211389/It has produced a really strong T-phase wave
the burst of signal at ~ 02:07UT ( bottom trace)

it's actually been a really quiet year this year
average are well down for the M7.0 to 7.9 events

so far this year there have only been 4 events in that category
there avg up till around September would normally be around 12 with around 18 as a yearly avg
I haven't seen it this low for a really long timeDave

For perspective - http://www.canterburyquakelive.co.nz/

The U.S. Geological Survey said the magnitude 7.1 quake hit at 1:14 p.m. (2:15 p.m. EDT) and was centered near the Puebla state town of Raboso, about 76 miles (123 kilometers) southeast of Mexico City.

Earlier in the day, workplaces across Mexico City held earthquake readiness drills on the anniversary of the 1985 quake, a magnitude 8.0 shake that killed thousands of people and devastated large parts of the capital.

1. What caused the two recent earthquakes in New Zealand?

The two recent earthquakes in New Zealand were caused by tectonic plate movement along the boundary between the Pacific and Australian plates, known as the Hikurangi subduction zone. This area is known for its frequent seismic activity as the Pacific plate dives beneath the Australian plate.

2. How strong were the two earthquakes in New Zealand?

The first earthquake, which occurred on March 5, 2021, had a magnitude of 7.3 on the Richter scale. The second earthquake, which occurred on March 5, 2021, had a magnitude of 8.1, making it the strongest earthquake to hit New Zealand in nearly a decade.

3. Were there any fatalities or significant damage from the earthquakes?

Fortunately, there were no reported fatalities from the earthquakes. However, there were reports of minor injuries and damage to buildings and infrastructure in the affected areas. The earthquakes also triggered a tsunami warning, but it was later lifted as the waves did not reach dangerous heights.

4. Are aftershocks expected following these earthquakes?

Yes, aftershocks are common after large earthquakes. In fact, there have been numerous aftershocks following the two earthquakes in New Zealand, some of which have been as strong as magnitude 6.0. These aftershocks are expected to continue for several weeks or even months.

5. How do these earthquakes impact the rest of the world?

The earthquakes in New Zealand can have a ripple effect on the rest of the world due to their location on a major tectonic plate boundary. They can trigger seismic activity in neighboring countries and can also cause changes in the Earth's rotation and axis. Additionally, these earthquakes serve as a reminder of the importance of preparedness and disaster response in the face of natural disasters.
