San Diego spoke to around 50 Rotarians on Aug 16, 2011 about the burning issues that confronted his department. This was on the occasion of the Joint Club Meeting among the Rotary Club of Sto Domingo QC, Rotary Club of Kamuning, Rotary Club of Dilman Central, Rotary Club of Kamuning East and the Rotary Club of St. Ignatius. San Diego comes from the Rotary Club of Kamuning.

During the Joint Meeting, San Diego spoke about how his department was addressing colorum tricycles, tri-sikad on the streets, apprehending and fining traffic violators and parking problems in the city.
Then he zoomed in on the West Valley Fault System.
San Diego’s statement echoed a similar message by Philvolcs Director Renato Solidum Jr., who warned the public about this in 2009:
MANILA - Some 38% to 40% of Metro Manila's residential and mid-rise buildings, as well as 14% of the area's high-rise buildings, could be destroyed in the event of a 7.2 magnitude earthquake, which could happen anytime between now and the next 400 years, the chief of the Philippine Institute of Volcanology and Seismology said Wednesday.
Phivolcs Director Renato Solidum Jr. issued the warning during Wednesday's Senate hearing on climate change, which was chaired by Sen. Loren Legarda and Sen. Rodolfo Biazon. Source: abs-cbnnews.com

According to the US Geological Survey, the western side of the West Valley Fault System pushes northwards and the eastern side pushes southwards. A slip can cause an earthquake with an Intensity 7.3 to 7.7. Analysts estimate this scenario to happen once every 200-400 years.
Apparently, this fault was discovered as early as the 1920s, during the American occupation. When Manuel L. Quezon administered the city before the war, he wanted the West Valley Fault System to be established as an elongated park. It would be planted with trees on either side of the fault to prevent anyone from putting up a house close to or on top of the Fault. Apparently this plan was overtaken by war and his eventual death in the US mainland.
Today, the fault line is hidden underneath the floors of houses in plush subdivisions of Metro Manila.
San Diego realizes the implications of breaking this news to owners of the houses constructed on top or within 5 meters of either side of the fault. Yet he understands that it is his duty, no matter how unpopular, to inform these residents and advise them to vacate the houses immediately.
The grave danger is not limited to those along the fault line, San Diego emphasized. When an earthquake strikes, the whole land mass moves. Buildings several kilometers away from the Fault could still be devastated. Thus, it is the duty of everyone, not just those along the fault lines, to be prepared.
As citizens, what can we do under the imminent danger of this “act of God”? Prayer would certainly constitute part of our response. Preparedness is the other. A well-prepared citizenry may not save the whole city, but it would mean everything to every person that would receive a helping hand on that day that we pray would never come.
The Philippine Institute of Volcanology and Seismology offers educational trips to their premises, lectures, video documentaries and digital images to the public.
