Did you  know this earthquake happened on the same day in history ? 
Japan, 1891 -  Magnitude : 8 – 7000 people killied

Local time: October 28, 6am.  The Great Nobi Earthquake.
Over 7,000 deaths. The earthquake caused damage over a 4200 square mile area. The quake shook Japan from Toyko to Osaka, killing thousands of people. 130,000 houses were destroyed.
This earthquake may be the largest “on land” earthquake in the modern history of Japan.

Does something like “earthquake weather” exists ?
There is no such thing as “earthquake weather”. Statistically, there is an equal distribution of earthquakes in cold weather, hot weather, rainy weather, etc. Furthermore, there is no physical way that the weather could affect the forces several miles beneath the surface of the earth. The changes in barometric pressure in the atmosphere are very small compared to the forces in the crust, and the effect of the barometric pressure does not reach beneath the soil.

Did you  know this earthquake happened on the same day in history ? 
Yugoslavia, 1969 -  Magnitude : 6.4 – 20 people killied

This severe earthquake in the Banja Luka area of Yugoslavia killed 20, seriously injured 150, and left 65,000 homeless. Banja Luka, a city of about 50,000 inhabitants, located about 240 miles west of Beograd, had about 60 percent of the dwellings razed. Three neighboring villages were reportedly destroyed. Among the major buildings razed by the shock were the city hall, cultural center, 15 schools, and 5 doritories. A textile factory damaged during the earthquake began leaking sulphuric acid and other chemicals, contaminating the river and water supply.

Earthquakes and earthquake frequency in the Utah (ski) mountains
The Wasatch Range, with its outstanding ski areas, runs North-South through Utah, and like all mountain ranges, was produced by a series of earthquakes. The 386 km (240-mile) long Wasatch Fault is made up of several segments, each capable of producing up to a M7.5 earthquake. During the past 6000 years, there has been a M6.5+ about once every 350 years.

About Magnitude and Intensity values
The magnitude of an earthquake is a measured value of the earthquake size. The magnitude is the same no matter where you are, or how strong or weak the shaking was in various locations. The intensity of an earthquake is a measure of the shaking created by the earthquake, and this value does vary with location.

Earthquakes in Southern California
Each year the southern California area has about 10,000 earthquakes. Most of them are so small that they are not felt. Only several hundred are greater than magnitude 3.0, and only about 15-20 are greater than magnitude 4.0. If there is a large earthquake, however, the aftershock sequence will produce many more earthquakes of all magnitudes for many months.

What is a seiche ?
A seiche (pronounced SAYSH) is “an internal wave oscillating in a body of water” or, in other words, it is the sloshing of the water in any body of water, caused by the ground shaking in an earthquake. It may continue for a few moments or hours, long after the generating force is gone. A seiche can also be caused by wind or tides.

Epicenter and hypocenter of an earthquake
The hypocenter of an earthquake is the location beneath the Earth’s surface where the rupture of the fault begins. The epicenter of an earthquake is the location directly above the hypocenter on the surface of the Earth.


October 17 2012

Did you  know this earthquake happened on the same day in history ? 
Peru, 1966 -  Magnitude : 8.1

This earthquake, centering just off the coast from Callao, claimed about 125 lives and injured some 3,000 persons. The town of Huacho was the most severely damaged with over 20,000 inhabitants left homeless. A religious festival was being held in Callao and several were killed when some of the churches collapsed. One street in this city was split by a chasm several feet wide. In Lima, 2,300 houses suffered severe structural damage. Cars were tossed about, cornices plunged into streets, and traffic was snarled for hours. Landslides and huge ground cracks were reported along the Pan American Highway north of Ancon. This shock generated a tsunami with heights of 11.3 feet at La Punta-Callao.

Difference between a tidal wave and a tsunami
Although both are sea waves, a tsunami and a tidal wave are two different unrelated phenomena. A tidal wave is a shallow water wave caused by the gravitational interactions between the Sun, Moon, and Earth. A tsunami is a sea wave caused by an underwater earthquake or landslide displacing the ocean water.

Complex earthquake begins with tiny precursor followed by major events about 4 and 7 seconds after the onset.

Are there earthquakes on the moon ?
Moonquakes (“earthquakes” on the moon) do occur, but they happen less frequently and have smaller magnitudes than earthquakes on the Earth. It appears they are related to the tidal stresses associated with the varying distance between the Earth and Moon. They also occur at great depth, about halfway between the surface and the center of the moon.

Average motion of the San Andreas fault
The average rate of motion across the San Andreas Fault Zone during the past 3 million years is 56 mm/year (2 inches/year). This is about the same rate at which your fingernails grow. Assuming this rate continues, scientists project that Los Angeles and San Francisco will be adjacent to one another in approximately 15 million years. (USGS)

Somebody working at INGV Italy wrote :
Hundreds of staff (including myself) of the INGV in Italy are risking to find themselves without a new contract from 1 January 2013 on. This is a very grave situation, which threatens to completely paralyze not only the lives of the concerned people, but also the functioning of the whole institute, mainly the surveillance of seismic and volcanic activity in Italy. The round-the-clock service in the control rooms of the Earthquake Center in Rome, at the Vesuvius Observatory in Naples, and at the Etna Observatory in Catania might completely break down, and quick response to emerging crises might be hampered. You would be indirectly affected because real-time seismic data and webcams would be taken offline.
In this moment there are continuous meetings between different parties in order to seek for solutions, but my personal feeling, in this moment, is rather dark.

Pipeline design has avoided an ecological disaster during the M7.9 Alaska earthquake in 2002 
A powerful magnitude 7.9 earthquake struck Alaska on November 3, 2002, rupturing the Earth’s surface for 209 miles along the Susitna Glacier, Denali, and Totschunda Faults. Striking a sparsely populated region, it caused thousands of landslides but little structural damage and no deaths. Although the Denali Fault shifted about 14 feet beneath the Trans-Alaska Oil Pipeline, the pipeline did not break, averting a major economic and environmental disaster. This was largely the result of stringent design specifications based on geologic studies done by the U.S. Geological Survey (USGS) and others 30 years earlier. Studies of the Denali Fault and the 2002 earthquake will provide information vital to reducing losses in future earthquakes in Alaska, California, and elsewhere.

Did You Feel It (USGS) and I Have Felt It (ER)
Did You Feel It? Since the early 1990s, the magnitude and location of an earthquake have been available within minutes on the Internet. Now, as a result of work by the U.S. Geological Survey and with the cooperation of various regional seismic networks, people who experience an earthquake can go online and share information about its effects to help create a map of shaking intensities and damage. Such “Community Internet Intensity Maps” (CIIMs) contribute greatly toward the quick assessment of the scope of an earthquake emergency and provide valuable data for earthquake research.
Comment ER : The Earthquake-Report.com approach is sharing your real earthquake experience with our readers. Your experience is also used by the earthquake-report.com specialists in evaluating the  damage risk in the greater epicenter area. Earthquake-Report.com is the ONLY specialised and structured I Have Felt It source in the world.

Coping with seismic hazards
National maps of earthquake shaking hazards provide information essential to creating and updating the seismic design provisions of building codes used in the United States. Scientists frequently revise these maps to reflect new knowledge. Buildings, bridges, highways, and utilities built to meet modern seismic design provisions are better able to withstand earthquakes, not only saving lives but also enabling critical activities to continue with less disruption.

Did you  know this earthquake happened on the same day in history ?
Peru, 1969 – Magnitude : 6.4 – 136 people killed
This earthquake struck in the Pariahuanca area of Central Peru. The villages of Lampa and Chilifruta were completely razed, and nearby Comas was 60 percent destroyed. Reports indicate that at least 136 were killed and 216 or more injured. The seismic activity began on July 24, 1969, when a magnitude 5.9 shock caused severe damage. During this shock, a visible fault movement of .4-meter vertical displacement was produced. The Huancayo seismograph station, located 18 miles southwest of the epicenter of the main shock, recorded more than 220 aftershocks. These were decreasing until this stronger shock, which had the same epicenter and was 3 kilometers deeper, produced up to 1.6-meter vertical displacement and .7-meter horizontal displacement of the fault displaced by the July 24 shock. Many landslides and ground cracks were observed. More than 1,375 aftershocks were recorded through October 17 at the Huancayo station. All were generally light and caused no serious damage.

USA earthquake hazard maps – a necessity for engineering
Hazard Maps show the distribution of earthquake shaking levels that have a certain probability of occurring in the United States. These maps were created to provide the most accurate and detailed information possible to assist engineers in designing buildings, bridges, highways, and utilities that will withstand shaking from earthquakes in the United States. These maps are used to create and update the building codes that are now used by more than 20,000 cities, counties, and local governments to help establish construction requirements necessary to preserve public safety.
