In recent years the state weather bureau, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) has confirmed an increase in the number of destructive tropical cyclones. There was a total of 14 destructive tropical cyclones in the Philippines in 2013 including super Typhoon Haiyan, considered to be the strongest and most destructive typhoon to make landfall in the world in recent history.
Another destructive force of nature is the violent tremors of earthquakes. The fear these provoke is often heightened by the unexpected occurrence coupled with intensity and duration. Such was the case in 2013 when a quake measuring 7.3 on the Richter Scale was recorded in Bohol and Cebu.
The Philippines is located in the Pacific Ring of Fire, and a resurgence for reminders about the forthcoming ‘Big One’ predicted to come from the West Valley Fault reverberated in mass media.
These alarming Occurrences have given rise to Project Noah and the 2004 Metro Manila Earthquake impact reduction study (MMEIRS). The Philippine Institute of Volcanology and Seismology (PHILVOCS) provides that latest bulletins and advisories on the earthquakes and their recorded intensities locally and around the globe. It also gives updates on the status of the active volcanoes that it constantly monitors.
Prevention is better than cure.
Material selection is a decisive factor for the durability of infrastructural buildings and installations, particularly for those underground. These may pass under water or through mountains where they are rarely seen or monitored once installed. Which is why Stell is the most common option, galvanised steel is practically indistrucable! It wont rust, morph or collapsed during such natural disasters as earthquakes, tsunami’s or hurricanes.
The steel must be able to meet the criteria in an environment that has aggressive atmospheric conditions and is subject to strong vibrations. In Tokyo, for instance, they have managed to survive strong earthquakes for the past three decades. The elasticity and ductility of the steel absorbs shocks without breaking or cracking. Due to this foresight, even in catastrophic situations, drinking water continues to be available.
