The Challenger Deep in the Mariana Trench is the deepest known point in Earth's oceans
11.87 miles/ 19.1 KM
EAST coast of north island
“NZ is very prone to quakes. 7 is not that unusual.”
All those beautiful places seem to have a big downside. Earthquakes, Volcanoes, liberals...
So, it’s either a7.1 or 7.2, off the east or west coast, at a depth of 19.1 miles or 19.1 km, which is either shallow or deep, and provides a small/large chance of tsunami.
That’s it exactly!
An earthquake can occur underground below the lowest part of the ocean.
That is perhaps why there is confusion.
The quake hit 105 miles northeast of Gisborne at depth of 19.1 miles.
I really think though that must have been the depth below the sea bed, not the water depth as the deepest part of any ocean is 36,000+ feet or a little over 6 miles deep. So I was interpreting the depth that they were referring to, incorrectly. It is the only thing that makes sense. Since it is not very far off of shore there is really no telling how deep the water is at that distance from shore.
Oops....yeah you are correct.
Yeah that is what I finally concluded they must be talking about. I thought 19 miles was awfully deep for any ocean depth, and I was correct as the deepest is a little over 6 miles in depth.
I don’t think and “earth” quake can happen in the water....
I still remember what happened to Christchurch in New Zealand in 2011 when a series of large earthquakes pretty much destroyed all of that city’s downtown and forced the 2011 Rugby World Cup to abandon several games that was supposed to be played in that city—the economic damage was gigantic. It may be 2025 before that city full recovers.
I suggest that if you can, go to YouTube ‘dutchsinse’, to avail oneself of a daily earthquake update, and areas to be watchful for future seismic events.
“I don’t think an “earth” quake can happen in the water....”
Earthquakes do not happen in the water. They happen in the “Earth” below the level of the depth of the water.
I’m glad you understand that..
I got it off of the USGS.
Absolutely 19 miles (or even 19 kilometers) is deep in the earth by any ordinary standard, but the earthquake guys have their own peculiar way of looking at it.
“Quakes can strike near the surface or deep within the Earth. Most quakes occur at shallow depths, according to the U.S. Geological Survey. Italy’s quake was very shallow, originating between 2 1/2 miles (4 kilometers) and 6 miles (10 kilometers) underground, according to Italy’s geological service and the USGS. The magnitude measurements also varied slightly — between magnitude 6 and 6.2. By contrast, the 6.8 quake in Myanmar was deeper — at 52 miles (84 kilometers), which is considered an intermediate depth.”
What made you think that I said that earthquakes happen in the ‘water’? I said no such thing.
Oh okay.
