It is estimated that there are 500,000 detectable earthquakes in the world
each year. 100,000 of those can be felt, and 100 of them cause damage.

It is thought that more damage was done by the resulting fire after the 1906
San Francisco earthquake than by the earthquake itself.

A seiche (pronounced SAYSH) is what happens in the swimming pools
of Californians during and after an earthquake. It is “an internal wave
oscillatingin a body of water” or, in other words, it is the sloshing of the water
in your swimming pool, or 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.

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.

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.The Wasatch Range, with its outstanding ski areas, runs North-South through Utah, and like all mountain ranges it was produced by a seriesof 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 6,000 years, there has been a M6.5+ about once every
350 years, and it has been about 350 years since the last powerful
earthquake, which was on the Nephi segment.

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.
From 1975-1995 there were only four states that did not have
any earthquakes. They were: Florida, Iowa, North Dakota,
and Wisconsin.

The core of the earth was the first internal structural element to be
identified. In 1906 R.D. Oldham discovered it from his studies
of earthquake records. The inner core is solid, and the outer core is liquid
and so does not transmit the shear wave energy released during
an earthquake.

The swimming pool at the University of Arizona in Tucson lost water from
sloshing (seiche) caused by the 1985 M8.1 Michoacan, Mexico earthquake
2000 km (1240 miles) away.

Earthquakes occur in the central portion of the United States too!
Some very powerful earthquakes occurred along the New Madrid fault
in the Mississippi Valley in 1811-1812. Because of the crustal structure
in the Central US which efficiently propagates seismic energy,
shaking from earthquakes in this part of the country are felt at a
much greater distance from the epicenters than similar size quakes in
the Western US.

The San Andreas fault is NOT a single, continuous fault, but rather is actually a
fault zone made up of many segments. Movement may occur along any of
the many fault segments along the zone at any time. The San Andreas fault
system is more that 1300 km (800 miles) long, and in some spots is as much as
16 km (10 miles) deep.

The world’s deadliest recorded earthquake occurred in 1556 in central China.
It struck a region where most people lived in caves carved from soft rock.
These dwellings collapsed during the earthquake, killing an estimated
830,000 people. In 1976 another deadly earthquake struck in Tangshan,
China, where more than 250,000 people were killed. they are much too small to
be seen on enough stations to obtain a location.

The deepest earthquakes typically occur at plate boundaries where the Earth”s
crust is being subducted into the Earth’s mantle. These occur as deep as
750 km (400 miles) below the surface.

Alaska is the most earthquake-prone state and one of the most seismically
active regions in the world. Alaska experiences a magnitude 7 earthquake
almost every year, and a magnitude 8 or greater earthquake on average every
14 years.

The majority of the earthquakes and volcanic eruptions occur along plate boundaries such as the boundary between the Pacific Plate and the North
American plate. One of the most active plate boundaries where earthquakes
and eruptions are frequent, for example, is around the massive Pacific
Plate commonly referred to as the Pacific Ring of Fire.

The earliest recorded evidence of an earthquake has been traced back to 1831 BC
in the Shandong province of China, but there is a fairly complete record starting
in 780 BC during the Zhou Dynasty in China.


It was recognized as early as 350 BC by the Greek scientist Aristotle that
soft ground shakes more than hard rock in an earthquake.

The cause of earthquakes was stated correctly in 1760 by British engineer
John Michell, one of the first fathers of seismology, in a memoir where he
wrote that earthquakes and the waves of energy that they make are caused
by “shifting masses of rock miles below the surface”.

In 1663 the European settlers experienced their first earthquake in America.
Human beings can detect sounds in the frequency range 20-20,000 Hertz.
If a P wave refracts out of the rock surface into the air, and it has a
frequency in the audible range, it will be heard as a rumble. Most earthquake
waves have a frequency of less than 20 Hz, so the waves themselves are usually
not heard. Most of the rumbling noise heard during an earthquake is the
building and its contents moving.

When the Chilean earthquake occurred in 1960, seismographs recorded
seismic waves that traveled all around the Earth. These seismic waves shook
the entire earth for many days! This phenomenon is called the free oscillation
of the Earth.
