No. Many earthquakes have no impact. The majority of earthquakes are so minor that they can't even be felt.
No. The vast majority of earthquakes occur at or near plate boundaries.
The US Geological Survey (USGS) National Earthquake Information Center records statistics for earthquakes in the US and worldwide. Between 2000 and 2011 the average number of earthquakes in the US was 3,820 per year that are magnitude 2.5 or higher.The majority of those earthquakes in the US are in Alaska and California with Hawaii in third place.http://earthquake.usgs.gov/earthquakes/states/top_states.php
Indirectly. The movement of tectonic plates is the cause of the majority of earthquakes. Earthquakes can cause landslides.
Yes, earthquakes happen every day around the world. However, the majority of these earthquakes are minor and go unnoticed by people. Stronger earthquakes that can cause damage are less frequent.
Quick answer: Plate Bounderies.
The majority of earthquakes occur on or near fault lines - the boundaries between tectonic plates. To actually see where earthquakes occur, try finding a historical seismicity map.
On average, there are about 20,000 earthquakes each year that are strong enough to be felt. This number can vary from year to year. The majority of earthquakes are small and go unnoticed by people.
the San Andreas Fault
the majority of earth quakes in the USA occur in California and in Alaska
That is impossible to tell. Smaller earthquakes occur more frequently, to the extent that the majority of earthquakes are too small to event be felt. Without a sophisticated seismic network, many earthquakes will not even be detected.
The majority of earth's volcanoes and earthquakes occur near the boundaries of tectonic plates. Therefore, an area that has volcanoes is likely to be prone to earthquake as well.
