They are winding up for another seige of strong quakes:

I missed 10.5. How was it? Since I have heard nothing since its initial showing, I would guess it was not a particularly memorable movie.

Tremor felt in Greek capital during Olympics
(08-24) 07:22 PDT ATHENS, Greece (AP)
A small earthquake rattled some Olympic venues Tuesday. There were no reports of injuries or damage.
The Athens Geodynamic Institute said the tremor had a preliminary magnitude of 4.5 and occurred at 3:38 p.m. local time. It was centered about 42 miles northeast of Athens, 12 miles beneath the Aegean Sea.
"There is no reason to panic. It was a very small quake," said Giorgos Stavrakakis, a seismologist with the Geodynamic Institute.
The press table shook at the baseball venue at the Helliniko Complex near the coastline.
"Like somebody was pounding the keyboard too hard," one reporter said. Other said they didn't notice anything.
Venues including the Olympic Village and the 9,000-seat Ano Liossia Olympic Hall for wrestling and judo were built near the fault line and designed to withstand a potentially massive quake.
International Olympic Committee took the unprecedented step of buying insurance in case the games were called off due to terrorism or natural disasters, such as earthquakes.
Earthquakes are common in Greece, one of the most seismically active countries in Europe.
In 1999, a 5.9-magnitude quake near Athens killed 143 people, injured about 2,000 and left thousands more homeless.
An earthquake also hit Nagano, Japan, during the 1998 Winter Games, jolting athletes and spectators but causing no major damage.

wow, thanks for posting that Cheryl.
the AM is back in Cali and i am worried about the big one supposed to hit by Sept 5 (although we all know how reliable predictions are).

There have been several sizeable quakes in Greece lately. I have heard of nothing bad happening which is a good thing.
California has had two strong quakes near Parkfield where the San Andreas Fault has made life difficult before. They are warning of aftershocks.
== AFTERSHOCK PROBABILITY REPORT ==
Southern California Seismic Network (TriNet) operated by Caltech and USGS
Version 1: This report supersedes any earlier probability reports about this event.
MAINSHOCK -
Magnitude : 5.0 Ml
Time : 29 Sep 2004 03:54:53 PM PDT
: 29 Sep 2004 22:54:53 UTC
Coordinates : 35 deg. 23.31 min. N, 118 deg. 37.24 min. W
Event ID : 14095628
STRONG AFTERSHOCKS (Magnitude 5 and larger) -
At this time (17 hours after the mainshock) the probability of a
strong and possibly damaging aftershock IN THE NEXT 7 DAYS is
less than 10 PERCENT.
EARTHQUAKES LARGER THAN THE MAINSHOCK -
Most likely, the recent mainshock will be the largest in the sequence.
However, there is a small chance (APPROXIMATELY 5 TO 10 PERCENT) of an
earthquake equal to or larger than this mainshock in the next 7 days.
WEAK AFTERSHOCKS (Magnitude 3 to 5) -
In addition, up to approximately 10 SMALL AFTERSHOCKS are expected in
the same 7-DAY PERIOD and may be felt locally.
This probability report is based on the statistics of aftershocks typical for
California. This is not an exact prediction, but only a rough guide to
expected aftershock activity. This probability report may be revised as more
information becomes available.
Background Information About Aftershocks
Like most earthquakes, the recent earthquake is expected to be followed
by numerous aftershocks. Aftershocks are additional earthquakes that
occur after the mainshock and in the same geographic area. Usually,
aftershocks are smaller than the mainshock, but occasionally an
aftershock may be strong enough to be felt widely throughout the area
and may cause additional damage, particularly to structures already
weakened in the mainshock. As a rule of thumb, aftershocks of
magnitude 5 and larger are considered potentially damaging.
Aftershocks are most common immediately after the mainshock; their
average number per day decreases rapidly as time passes. Aftershocks
are most likely to be felt in the first few days after the mainshock,
but may be felt weeks, months, or even years afterwards. In general,
the larger the mainshock, the longer its aftershocks will be felt.
Aftershocks tend to occur near the mainshock, but the exact geographic
pattern of the aftershocks varies from earthquake to earthquake and is
not predictable. The larger the mainshock, the larger the area of
aftershocks. While there is no "hard" cutoff distance beyond which an
earthquake is totally incapable of triggering an aftershock, the vast
majority of aftershocks are located close to the mainshock. As a rule
of thumb, a magnitude 6 mainshock may have aftershocks up to 10 to 20
miles away, while a magnitude 7 mainshock may have aftershocks as far
as 30 to 50 miles away.

My relatives there did not feel it but sent the following:
From CNN:
Parkfield Quake Preliminary magnitude of 5.9
Tuesday, September 28, 2004 Posted: 1:50 PM EDT (1750 GMT)
PARKFIELD, California (AP) -- An earthquake with a preliminary magnitude of
5.9 struck central California on Tuesday and was felt as far north as San
Francisco and Sacramento, according to the U.S. Geological Survey.
An aftershock of 5.0 magnitude struck four minutes later.
Police said there were no immediate reports of damage or injuries.
In nearby Redwood City, the quake delayed the murder trial of Scott
Peterson after a juror reported feeling the tremors.
Thousands of people from throughout the state reported feeling the quake.
"It rattled everything hanging on the walls and the chandelier was
swinging. It didn't do any damage to our house. There were two shakers, one
right after the other," said Ben Brown, who lives in Paso Robles.
The earthquake, which struck at 10:15 a.m. (1715 GMT) was centered 9 miles
(14 kilometers) south of Parkfield and 17 miles (27 kilometers) north east
of Paso Robles, scene of an earthquake that killed two people in December
2003.
Parkfield, located on the San Andreas fault, is known as the earthquake
capital of California.

Powerful earthquake rocks Taiwan and southern Japan
Fri Oct 15, 6:19 AM ET
TAIPEI (AFP) - A powerful earthquake measuring 7.0 on the Richter Scale shook Taiwan, sparkling several fires and prompting people to flee swaying high-rise buildings but causing no serious damage.

The quake led to a dozen technicians being trapped in elevators of the world's tallest building, Taipei 101, for several minutes but the 508-metre (1,666-feet) structure remained intact, passing a key safety test.
The earthquake struck shortly after noon (0408 GMT) and was also felt in Japan's southern Okinawa chain, where the Meteorological Agency said it measured 6.6 on the Richter Scale.
Neither Taiwan nor Okinawa reported serious injuries or damage from the tremor, which was located at sea some 109 kilometres (68 miles) off Taiwan's northeastern coast. Its focus was 58 kilometres below sea
