7.5+ quakes ,depth wise since 1900

I am sorry

I did not notice that USGS search site have one option to search with respect to depth in km

Accordingly I have searched 7+ quakes from 1st January to 1900 till today

There are in all 1482 such quakes

The breakup depth wise is as follows

1) 0 km to 100 kms....1250 quakes

2)100 to 200 kms.....94

3)200 to 300 kms....32

4)300 to 400 kms....13 quakes

5)400 to 500 km....16 quakes

6)500 to 600 km..  47

7) 600 to 700........30

8)700 to 800 km....0

9) 800 to 900 kms..0

watch there are less quakes in the range of 300 km to 500 kms only

It increases again between 500 to 700 kms

Thus is exactly as per my deep quakes hypothesis
