The number is definitely growing. The severity is also growing but by a relatively small pace.

Wiki says that the stations that record them have multiplied, so they record more and more earthquakes, but, as far as I have read, the number of the earthquakes IS growing.

Here's some article that proves the growing size. ("funny" that 7 - 7.99 is less when 8 - 8.99 is more!)
The number and severity of earthquakes are not necessarily increasing, but our ability to detect and record them has improved over time. This enhanced monitoring may lead to the perception of more frequent or severe earthquakes. It is important to consult scientific data and research to understand the true patterns and trends in seismic activity.

What event's magnitude is expressed as a number on the Richter Scale?
Earthquakes are the events whose magnitude is expressed as a number on the Richter Scale.
What is the greatest number on the ricther scale?
The highest number on the Richter scale is 10. However, in practice, most earthquakes do not exceed a magnitude of 9.5.
How many earthquakes since 1914?
Data from the past 100 years suggests that the number of earthquakes per year arranged by magnitude is:Magnitude : Average Number Annually8 and higher:17 - 7 : 9 to 156 - 6.9 : 1345 - 5.9 : 13194 - 4.9 : 13,0003 - 3.9 : 130,0002 - 2.9 : 1,300,000The total number is therefore around 1, 500, 000 a year. Given that the Earth is about 4.5 billion years old and solid enough for earthquakes for about 4 billion of that number, the total number of earthquakes in the Earth's history would be about 6x1015 or 6,000 trillion.
What is the Average number of earthquakes in san Diego per year?
On average, there are about 200-300 earthquakes in the San Diego area each year, but most of these are too small to be felt by people. The region is seismically active due to its location near the San Andreas Fault.
The amount of earthquakes yearly?
On average, there are around 50,000 earthquakes every year, with the majority being too small to be felt by people. The number of significant or damaging earthquakes varies each year, influenced by various factors. Monitoring and measuring technologies have improved over time, leading to a better understanding of earthquake activity globally.
Does central Europe have the greatest number of earthquakes?
Europe doesn't have the greatest number of earthquakes.
What is the severity scale for earthquakes?
The severity of earthquakes is typically measured using the Richter scale or the moment magnitude scale. The Richter scale measures the amplitude of seismic waves and assigns a numerical value, while the moment magnitude scale measures the total energy released by an earthquake. Both scales are logarithmic, meaning that each whole number increase in value represents a tenfold increase in the amplitude or energy release.
What will happen if convection in the mantle increased?
There is no reason to think that convection in the Earth's mantle is going to increase; indeed, I expect it to decrease over time. However, if it were to increase, the result would be an increasing number and severity of earthquakes, and faster continental drift.
What 2 states have the smallest number of earthquakes?
If its in US, Florida and North Dakota are reported to have very less number of earthquakes. Also Antarctica is a continent which has very fewer earthquakes.
How many people died in natural disasters?
On average, around 60,000 people die from natural disasters each year, although the number can vary greatly depending on the severity and frequency of the events. This number includes deaths from earthquakes, hurricanes, floods, wildfires, and other natural events.
Are the number of earthquakes in the world increasing?
NO http://earthquake.usgs.gov/earthquakes/eqarchives/year/eqstats.php
What determines the severity of aphasia?
The severity of aphasia is related to a number of factors, including the severity of the condition that brought it about, general overall health, age at onset, and numerous personal characteristics that relate to motivation.
How many autistic children are there currently living in the world?
The CDC estimates that one in every one hundred and ten (1/110) children have an autism spectrum disorder and many believe this number is growing. Autism varies in severity.
What 2 US states have the smallest number of earthquakes?
Florida and North Dakota have the fewest earthquakes in the US.
Are the number of McDonald employees shrinking or growing?
growing
Areas of the US where the risk of earthquakes are high?
The most frequent number of earthquakes in U.S. are in Alaska followed by California.
What state has the least number of earthquakes?
Rhode Island
