Most earthquakes are classified as "microquakes" that fall in the range of 1.0 to 1.9 on the Richter scale. Several million such quakes occur each year - practically continuously.
A bit over one million quakes a year fall in the range from 2.0 to 2.9 on the Richter scale.
A bit over 100,000 quakes with a magnitude of 3.0 to 3.9 occur each year
Light earthquakes in the range from 4.0 to 4.9 happen about 10,000 to 15,000 times each year.
About 1,000 to 1,500 moderate earthquakes in the range of 5.0 to 5.9 shake things up each year.
Strong earthquakes (in the range of 6.0 to 6.9) hit 100 to 150 locations on the earth each year.
We get 10-20 major earthquakes (magnitude 7.0-7.9) each year.
An earthquakes in the range from 8.0 to 8.9 might occur once a year somewhere on the earth.
Earthquakes of magnitude 9.0 or greater only occur once every 10 to 50 years.
Earthquakes change earth by moving earths plates
Because they knock buildings down. People are bothered when buildings fall onto them.
There will be a lot of destruction, Buildings will fall down and people will become injured or lose their lives.
A building that can resist earthquakes can fall down if you put more pressure on them then they were designed to withstand. For example if there was to be a major subsidence directly under half of the building it is likely that it will fall over.
They use more of a flexible walls and beams instead of strong flat beams, so that in an earthquake they can sway, not fall.
While it is not impossible for a 10.0 magnitude earthquake to occur, the likelihood is very low. The Richter scale is logarithmic, so each whole number increase represents a tenfold increase in amplitude. Most earthquakes fall within the 7-9 range on the scale.
Temples fall in earthquakes all the time. And they kill whoever is inside them at the time.
Usually very rarely people die in a magnitude 5 earthquake on the Richter scale. On the scale, 5 is an "intermediate" earthquake and the damage includes, bricks fall, plaster cracks and slight damage is inflicted on buildings.
The Number of TopoSheets of 50000 scale fall in to 250000 scale will be 16. Please tell me what would be the distance in KM in One Degree of 250000 scale toposheet
Because the earthquakes in Haiti caused the buildings to fall down.
They fall into the cracks.
Earthquakes occur to the land because it will shake and make most of the weak buildings fall
It makes them fall.

The economies of scale attainable from large scale production fall into two categories. Internal and External.
If the elevator is in free fall, you and the scale would be accelerating downward at the same rate. In this case, the scale would read zero, because you and the scale are essentially falling together with the same acceleration due to gravity.
