Earthquake Report comment :
A moderate shallow earthquake struck the greater Tokyo area in the Japanese night.
Although it will probably not be dangerous, a lot of people woke up by the light shaking.
If the preliminary location will be confirmed, the epicenter lies in the immediate vicinity of Narita International airport.
16 minutes earlier another moderate earthquake of M 4.7 , but much deeper in the mantle of the earth, shook another part of Honchu

Most important Earthquake Data:

6 million Mexicans participate in massive Magnitude 8.1 earthquake drill

Translation of an article of the Mexican newspaper : La Jornada
Please read the full Spanish report on the following webpage

Click on the picture to see it at normal dimensions

More than 6 million citizens participated in the simulation organized by the Federal District as a preventive measure against a possible earthquake measuring 8.1 degrees on the Richter scale, which would have generated a lot of damage in Mexico City.

At 11 am the alarm went off which allowed the evacuation of buildings.

The activities were supervised by the head of the Federal District out of the Old City Hall. Strategic objectives of the trial is to protect the lives of citizens.

To achieve this goal, effective preparation is necessary to evacuate all buildings or take shelter in safe areas, with emphasis on the school population, hospital facilities and places with a very high concentration of people, like the Metro Public Transport System that moves half a million passengers around that time.

Six empowerment groups are specializing in different areas in emergency cases  + 1,500 brigades will go to suburbs where their presence will be required.

Security personnel and police began evacuating hundreds of passengers from trains, subway platforms etc.

Some people were frightened because they did not know that it was a simulation.

The security officers indicated where the exits could be found to avoid injuries from pushing, falling etc. After several minutes, people were evacuated without any incident.

Despite the setbacks, the passengers expressed their willingness to follow the preventive measures. “I wish there were two or three simulations a year to be prepared for a major earthquake and to prevent accidents such as occurred 25 years ago” said a train passenger.

Banks unfortunately refused to participate in the drill.

Government buildings were evacuated, in the same way that public and private companies vacated their offices. On streets and avenues people were out of buildings, some in a hurry and others with calm.

The average time taken for evacuation in case of an earthquake of that magnitude exceeded 60 seconds.

In Benito Juárez it took one minute 49 seconds to evacuate 2,100 people. 150 businesses participated in the exercice.

In the Delta Park Mall an explosion was simulated and the square was cleared completely. Emergency and security personnel were also present.

Powerful earthquake near Salina Cruz, Mexico (Oaxaca)

Earthquake Report comment :
Epicenter of the earthquake is only 40 km from the town of Salina Cruz in the province of Oaxaca.
De pending on the data source the hypocenter of this earthquake is located in between 10 km and 58 km (a big difference).
Salina Cruz has a population of 73,468 (latest census).
San Mateo de Mar, even a little closer to the epicenter, has a population of 5,441.
Both populated centers lie in the immediate vicinity of the subduction zone where the Cocos plate is diving under the Caribbean plate, thus creating a dangerous earthquake zone.
This area has regular earthquakes and people are used to shocks from time to time. Earthquake-Report.com predicts no damage or injuries from this earthquake, although every earthquake can be felt differently.
This earthquake is hardly reported by the Mexican press. All the spots are still on the aftermath of tropical storm “Karl” who is claiming at least 18 victims.

Wikipedia info on Salina Cruz :
Salina Cruz is a major seaport on the Pacific coast of the Mexican state of Oaxaca. It is the state’s third-largest city and is municipal seat of the municipality of the same name. It is part of the Tehuantepec District in the west of the Istmo Region. The city had a 2005 census population of 71,314 persons, while its municipality, with an area of 113.55 km² (43.84 sq mi) had a population of 76,219, the state’s fourth-largest municipality in population. The port expanded in the late 19th century due to its location at the southern terminus of the Tehuantepec National Railway, which carried freight across the Isthmus of Tehuantepec. It is situated near the mouth of the Río Tehuantepec, on the open coast of the Isthmus of Tehuantepec, and has no natural harbour. There was only a small Native American village before Salina Cruz was chosen as the Pacific terminus of the railway, whereupon a modern town was laid out and built on adjacent higher ground.

Moderate Greece earthquakes strike in the same area than the 1303 historic deadly earthquake

1303 Greece earthquake - Map Courtesy USGS

Earthquake Report comment :
Epicenter in (the Mediterranean Sea) between the Greek island of Crete and the islands of Kassos and Karpathos.
Almost exactly the same spot than the devastating earthquake and tsunami from 1303 (although there was not a good knowledge on earthquakes in that era).
Today’s earthquake brings memories back to life and revives the possible dangers for mega-earthquakes in this part of Europe.
Ask 1000 tourist who are leaving for Greece for a summer vacation what they should do in case of an earthquake ? If 1% knows the answer, it will be a great result.  Based on history and present, it is a shame that tourists are not informed on how to behave in case of an earthquake.

Wikipedia report on this major historic event :
The 1303 Crete earthquake occurred at about dawn on 8 August. It had an estimated magnitude of about 8 and triggered a major tsunami that caused severe damage and loss of life on Crete and at Alexandria.

The earthquake and the tsunami are recorded as having a devastating impact on Heraklion, Crete.[3] Detailed information is available from reports made by representatives from Heraklion (then Candia) to the controlling Venetian administration, written on the day of the earthquake and twenty days later. They describe the extent of damage to the main public buildings of Candia and castles over the whole island. The reports also mention that most of the victims were women and children, without giving numbers.[ There was also massive flooding at Alexandria. Many ships were destroyed, some of them carried up to 2 miles (3.2 km) inland. The port city of Acre, on the Levantine coast, was also affected; buildings were destroyed and people swept to their deaths.

In Egypt the earthquake caused severe damage in Cairo, toppling minarets on many mosques. In Alexandria the city walls were mostly destroyed and the lighthouse was badly damaged

Tectonic explanation
The Hellenic arc, the most likely location for this earthquake, is an arcuate tectonic feature related to the subduction of the African Plate beneath the Aegean Sea Plate. It is one of the most active seismic zones in western Eurasia and has a history of large earthquakes that also affect Egypt

Most important Earthquake Data:
Magnitude : M 4.3, M 4.2 and M 4.4
Date and Time : 2010-09-21 02:07, 02:09 and 04:15
Depth (Hypocenter) : 30, 15 and 10 km
Geo-location(s) :
59 km S Kárpathos
176 km E Iráklion (Heraklion), Crete, Greece
