How many earthquakes over magnitude 8 were recorded in 2000?
27 earthquakes have happened from 1995 to 2008.
What is the average number of earthquakes per year?
I have been doing some maths and found that in the average year, you'd get about 3,610,364(3 million, 6hundred and 10 thousand, 3hundred and sixty four) earthquakes in a year. Ofcourse these are all around the globe. About 2 million of these are bellow 2 on the Richter scale.
Where was the latest earthquake?
Somewhere around the world there is probably at least one earthquake each day if not more. The U.S. Geological Survey (USGS) National Earthquake Center keeps track of earthquakes around the world. According to the USGS there are over a million earthquakes each year around the world -- that's on average 3,561 per day or 2.5 per minute. Only a portion of these are recorded (~20 - 30K per year) because most occur over remote areas or in the ocean. For the latest refer to the list USGS keeps for recent earthquakes world-wide for last 7 days in related links section below. USGS also provides a real-time KML feed. There are also lists for historic earthquakes by year or region.
Do earthquakes occur in the central portion of the US?
Yes, earthquakes do occur in the central portion of the US, although they are less frequent and less intense compared to regions like the west coast. The New Madrid Seismic Zone, located in the central US near the Mississippi River, is known for its historic earthquake activity.
How many earthquakes are there in one year?
On average there are 20,000 - 30,000 recorded earthquakes recorded worldwide per year according to the USGS. Only a portion of these are recorded because most occur over remote areas or in the ocean.On average only one of those earthquakes is 8 or higher each year.However, the USGS estimates that several million earthquakes occur in the world each year and go undetected because they hit remote areas or have very small magnitudes.
Which earthquake scale would be most appropriate to describe historic earthquakes where seismograph records are not available?
The Mercalli intensity scale would be most appropriate for describing historic earthquakes where seismograph records are not available. This scale categorizes earthquakes based on the observed effects on people, buildings, and the environment rather than on instrumental measurements. It provides a qualitative description of the earthquake's intensity and impact.
Scientists don't know the Richter scale for earthquakes that happened before seismometers were invented but they can work out mercalli numbers for these earthquakes why is this?
They can calculate intensity based on how the earthquake was felt at different places and what damage occurred from old newspaper reports and other historic documents.
Which earthquake was the most powerful in history?
According to the U.S. Geological Survey (USGS) National Earthquake Information Center (NEIC) there are over a million earthquakes each year around the world -- that's on average 3,561 per day or 2.5 per minute. Only a portion of these are recorded (~20 - 30K per year) because most occur over remote areas or in the ocean.The NEIC collects records for earthquakes world-wide and makes available lists of earthquakes by region, year, magnitude/intensity,etc.To see list of more recent (or historic) earthquakes visit USGS Earthquake Hazards Program.
How many earthquakes were there in 2013 in the US?
There were over 1,600 earthquakes in the continental US in 2013 with magnitude 2.5 and greater not including Alaska and Hawaii. For 2000 - 2012 the average number of measured earthquakes per year was 3,822.The total count is much higher because many go undetected because they hit remote areas or have very small magnitudes.To see a list of more recent (or historic) earthquakes, visit the USGS Earthquake Hazards Program.
How many earthquakes over magnitude 8 were recorded in 2000?
27 earthquakes have happened from 1995 to 2008.
How many large earthquakes were there in 2012?
The list of earthquakes by year (1990-Present) or by country can be found at the USGS Earthquake Hazards website. In 2010 there was one earthquake magnitude 8 or greater, which was in Chile (M 8.8). The USGS provides a list of significant earthquakes for 2010 as well as a worldwide map of earthquakes for 2010 and previous years. See link below.
How many earthquakes have there been this year in 2012?
According to the USGS National Earthquake Information Center, as of 27 November 2012 there were an estimated 16,667 earthquakes worldwide and 3,836 in the United States alone (not including earthquakes smaller than magnitude 4.5 outside the United States).However, the USGS estimates that several million earthquakes occur in the world each year and go undetected because they hit remote areas or have very small magnitudes.To see a list of more recent (or historic) earthquakes, visit the USGS Earthquake Hazards Program.
How many earthquakes in 1995?
The following details from a USGS press release to summarize the year the Kobe Earthquake hit Japan in Jan. 16, 1995."Twenty-five earthquakes around the world registered a higher magnitude than the 6.8 magnitude Kobe 1995 earthquake, according to USGS records at its National Earthquake Information Center in Golden, Colo. Forty-seven "significant" earthquakes were recorded throughout the world in 1995, 22 more than occurred in 1994, but only about two-thirds the long-term average of 60 per year. A significant earthquake, according to the USGS, is defined as one that registers a magnitude of at least 6.5, or one of lesser magnitude that causes casualties or considerable damage.The USGS, using data from seismograph stations throughout the world, presently locates from 16,000 to 19,000 earthquakes each year having magnitudes of about 1.0 up to 8.0 or more."To see a list of more recent (or historic) earthquakes, visit the USGS Earthquake Hazards Program.

How many large earthquakes were there from 1990 to 2011?
On average, there are roughly 20,000 - 30,000 recorded earthquakes worldwide every year by the U.S. Geological Survey (USGS) National Earthquake Information Center. Of those, approximately 1 earthquake of magnitude 8.0 and higher (and 15 between M 7.0 - 7.9) occurs per year around the world. Some years have greater than average earthquakes such as 2007 in particular with 4 earthquakes of magnitude 8.0 or higher and 2008 with no earthquake higher than 7.9. The list of earthquakes by year (1990-Present) or by country can be found at the USGS Earthquake Hazards website. The USGS provides a list of significant earthquakes for each year starting from 1990 to present as well as a worldwide map of earthquakes. Lists for historical earthquakes from earlier years are also available. See link below.
