Although California is the most notorious for earthquakes, Alaska actually has the most per year, due to its large volcanic activity in the Aleutian Islands. Many other western states have large amounts of earthquakes as well. Regions of Arizona and Nevada bordering California have many earthquakes, as well as Washington and Oregon. Rocky Mountain states such as Wyoming, Idaho and Montana tend to have many earthquakes, although mostly minor (1-3.0 Richter scale) in size. Their activity is caused by the Yellowstone Supervolcano which feeds many of the parks' geysers and basins.
The Richter scale was originally developed to measure the strength or magnitude of moderate earthquakes (magnitudes less than 7). The surface wave magnitude scale was then developed by Richter and Guttenburg to allow larger earthquake magnitudes to be measured (up to 8). To measure large earthquakes the moment magnitude scale must be used. To measure the severity of earthquakes, the Modified Mercalli intensity scale is used in the US and the Macroseismic scale is used in Europe.
These are the Minor causes of Earthquakes:-a) Drilling of the earth for exploration of minerals.b) Collapse of cavern walls.c) Underground nuclear testing.d) Impact of meteorites on the surface of the earth.e) Construction of huge dams which increases rockpressure.f) Landslides in mountain areas.d) Carolyn
According to the US Geological Survey there are approximately 1,000,000 earthquakes around the world every year (although the vast majority of these are so small they can only be detected by sensitive scientific equipment). Of these 1,000,000, approximately 1/10 are large enough to be felt by humans. This means that on any day there will be on average 275 earthquakes around the world that can be felt. Perhaps even more surprisingly, on average there are around 100 earthquakes a year that are large enough to cause damage (however they often don't because they occur away from inhabited areas). This means there is a little under a 1 in 3 chance of there being a "large" earthquake on any given day. The British Geological Survey have published some data on the annual average frequency of earthquakes of varying magnitudes: Description : Magnitude : Frequency per year Great : > = 8.0: 1 Major : 7.0 - 7.9: 17 Strong : 6.0 - 6.9 : 134 Moderate : 5.0 - 5.9 : 1319 Light : 4.0 - 4.9 : 13,000 (estimated) Minor: 3.0 - 3.9 : 130,000 (estimated) Very minor : 2.0 - 2.9: 1,300,000 (estimated)
Delaware and rest of New England historically has had few earthquakes. The last shock to center in Delaware and cause minor effects occurred on May 8, 1906, In recent years, two minor tremors occurred in Delaware, one on the Lower Delaware in December 1937, and one near Wilmington in January 1944. The largest earthquake (Intensity VII) felt in Delaware was in 1871.
A seismograph records an earthquake while it is happening, but as of yet there are no machines that can predict earthquakes.
The building which houses Big Ben was built long before we worried about earthquakes. But England only rarely has very minor earthquakes.

No. Many earthquakes have no impact. The majority of earthquakes are so minor that they can't even be felt.
Names used include tremor, temblor, and seism. A "microseism" is a faint tremor caused by any of several sources (earthquake, avalanche, large waves, explosions). Colloquial terms for minor quakes are shakes, rumbles, or bumps.

Generally 2.0 - 3.9 is minor, less than 2.0 is micro.
It is the main cause of earthquakes. However you may get minor earthquakes due to volcanic activity or mass wasting events.
Occasionally, but there has only been minor ones
Earthquakes are measured by its magnitude which is commonly grouped in six classes from minor to great:8.0 and higher great7.0 - 7.9 major6.0 - 6.9 strong5.0 - 5.9 moderate4.0 - 4.9 light3.0 - 3.9 minor

Only minor ones and very rarely.
