Critical Information on Earthquake preparedness

Please allow me to share some critical information why earthquake preparedness is very urgent.
Here, I have provided some official earthquake preparedness materials that are downloadable. Please ignore all other unauthorized suggestions being spread irresponsibly through email, like those with the subject "Earthquake tips" and features something called "The triangle of Life." These are not endorsed by any recognized authority on the subject and may even endanger people's lives.

from What to do in case an earthquake hits By Cyril Bonabente, PDI Research Inquirer. Posted date: July 16, 2006. http://newsinfo.inq7.net/inquirerheadlines/nation/view_article.php?article_id=10071

The Metro Manila earthquake scenario that the Phivolcs determined on October 2004 remains a great concern.(1) This can now be viewed in the light of the December 26, 2004 Indian Ocean M9.0 - M9.3 Earthquake that triggered the killer Tsunamis.(2) (Before, what we remember more was the 1990 Luzon M7.8 Earthquake).

As directed by President Gloria Macapagal-Arroyo, a nationwide earthquake drill for schools was carried out at the start of the school year on 20 June 2006 at 9:00 AM. Coordinated by the Office of Civil Defense-National Disaster Coordinating Council (OCD-NDCC) in collaboration with the Philippine Institute of Volcanology and Seismology-Department of Science and Technology (PHIVOLCS-DOST) and the Department of Education (DepEd).

One year later, in October 12, 2005, Malacañang continues its earthquake preparedness activities.(3) You see, the scenario has been described by Phivolcs as inevitable...that a magnitude 7.0 to 7.2 earthquake can hit Metro Manila anytime. It is not a question of whether it will or will not occurs, it is a question of when it will occur, so we have all the reasons tobe prepared.
It has been 400-500 years since the last major earthquake. Such major event happens on the VFS every 400-500 years, if not 200 years. To read further, check out th e August 2002 JICA Study(4) and the previous 2000 study conducted by the Geologic Hazards Team of the Central Region U.S. Geological Survey.(5)

(4) "Metro Manila and Potential for Danger ....In and around Metro Manila, numerousearthquake sources exist, such as Valley Fault System (VFS), Philippine Faults, Lubang Faults, Manila Trench and Casiguran Faults. Among these, VFS, which transects the JICA Study area, is considered to cause the largest impact to Metro Manila area if it will become active. Recent studies show that VFS has ruptured twice to four times in the last 1400 years with a return period being approximately less than 500 years. And since no event of a major earthquake has been known along West Valley Fault since the 16th Century, active phases of the Valley Faults may be approaching. Results of many researches indicate that an estimated magnitude will be around 7 or higher."

(5) "The first 14C-based paleoseismic study of an active fault in The Philippines shows that a right-lateral fault on the northeast edge of metropolitan Manila poses a greater seismic hazard than previously thought. Stratigraphic, soil, and 14C data from exposures across the northern part of the west Marikina Valley fault indicate a recurrence interval of 200-400 years for magnitude 6-7 earthquakes on the fault."
