Marikina Valley Fault System
WHAT IF? A Doomsday Scenario
by Frederick Fabian
WHAT if a disaster of cataclysmic proportions hits Metro Manila, home to more than 15 million Filipinos—and the seat of the nation’s capital?
Thousands of lives will be lost and casualties can run to millions. It will be a harrowing sight that will surely bring the nation to its knees. That is, if we consider the potential disasters on a grand scale, such as the recent earthquake in Bohol and typhoon Yolanda (Haiyan) that razed big parts of Leyte to the ground.
What if, instead of the Visayas, Yolanda took a path straight through the heart of the National Capital Region?
The resulting storm surge would drive the waters of the Laguna Lake inland and inundate the lakeside barangays of Laguna and drown millions of people. The loss of lives and damage to property would be triple the Visayas count.
What if the Marikina Valley Fault System shifted and triggered a massive earthquake? Are we ready to deal with such a scenario?
The Philippines, after all, is located in the Pacific Ring of Fire, an area of the world that is susceptible to earthquakes and volcanic activity. The island republic is also considered one of the world’s most dangerous places, because we are a constant recipient of typhoon landfalls more than any large country in the world.
As grim as it may sound, an inconvenient truth is better than a comfortable lie.
The Marikina Valley Fault System extends from San Mateo, Rizal and runs through Makati, Marikina, Parañaque, Pasig and Taguig. It has been observed by Phivolcs and other scientific experts as a potential origin of large-scale earthquakes that can reach a magnitude of 7 or higher within Metro Manila.
A possible death toll, as predicted by experts, can reach 35,000, with an estimated 120,000 injuries. The earthquake will also require the evacuation of three million people from the potential disaster areas.
In a research done by the Metro Manila Earthquake Impact Reduction Study (MMEIRS), funded by Japan International Cooperation Agency (JICA) in 2004, it was revealed that a 7.2 magnitude earthquake can destroy 40% of residential buildings, fatalities numbering 114,000 and fires that will result to 18,000 more casualties.
While the eastern side of Metro Manila will suffer the brunt of the event, damage and consequential damage can affect the rest of the NCR. Dr. Norman Tungol of Phivolcs has advised that Metro residents, especially those living near the faultline, to be prepared for the worst, because earthquake prediction is not an exact science.
Aside from structural damage, another risk looming over the people of Metro Manila would be the possibility that reservoirs such as the Angat Dam would be damaged and cause flooding. Building collapse can cause electrical short circuits, petroleum and LPG leakages from storage tanks, among others, that would trigger fires, according to a report by online news site Bulatlat.com. Places susceptible to fires are Valenzuela, Caloocan, and the southern parts of Quezon City.
Newsfeeds in Facebook were filled with complaints and angry callouts about the incompetence of President Benigno Aquino III and his lack of political will in dealing with the recent typhoon. The complaints are well-placed and unquestionably valid: at the same space of the few hours when CNN correspondent Anderson Cooper was reporting on the lack of organized government efforts in Tacloban City, President Aquino was on the air with CNN’s Christiane Amanpour that everything is under control despite contrary evidence.
It wouldn’t be too far-fetched to say that the President is being cold to the plight of the people of Leyte, if his actions in the past week after the storm is to be gauged. After all, PNoy has been distant and detached from the real-life drama happening in Tacloban and surrounding towns, preferring to do a form of remote-control governance rather than be physically present where the people are suffering, where they are mourning the dead and where the children are going hungry. That appears to be too much for his constitution.
It seems that it is not something a privileged, upper-class-raised Noynoy can handle. How can a sheltered rich boy, the scion of Philippine political icons and hacienda landlords, possibly bear the harrowing sight of devastation and desperation when it’s taking place in front of him? The crisis is far from the safety and comfort of his Malacanang office. We can just imagine that he will treat the residents of Metro Manila the same way. Humans are creatures of habit, and if anything, the President is one. He has a terrible habit of placing the blame on someone else, as if he lacks the capability to own up responsibility.
Incompetence Is Matter Of Fact
As many rational and well-informed Filipinos would tell you, Malacañang has always been incompetent where it counts. Some may dismiss it as mere cynicism and pessimism. But several counts of wrong decisions and late responses to a crisis is an indicator not just of incompetence, but of impotence. We all know that this is not the first time that the Aquino administration has shown that it is incapable of delivering in crucial times. From the 2010 Manila Hostage Crisis, the growing unemployment rate despite his claims of economic growth, the 2011 vetoing of the budget provision for disaster management, to the mishandling of the pork barrel issue, the list just goes on.
Reputable news analysts and weather experts have predicted that the NCR can become the next ground zero based on past scientific data and environmental factors. There is more than enough evidence to support the possibility that significant parts of Metro Manila can and will be subjected to massive damage that can equal that of Tacloban and nearby Leyte towns. According to former Manila Chronicle newsman and science/technology writer Alan C. Robles, “a storm like Haiyan could bring the Philippine capital to its knees.”
In his interview with MMDA chairman Francis Tolentino, the official confirmed similar concerns by saying that it will be just like Tacloban, which was decimated to the ground when Yolanda struck. Tolentino confidently stated it will just be the same, if not worse, although he noted that some structures in Manila are better built to withstand typhoons. He significantly added, “It will also cause societal disruption.”
Welcome To Floodland
Metro Manila is 638 square kilometers in area, composed of 16 cities, one municipality, and has up to around 15 million people living in it. It is surrounded by bodies of water and flood-prone areas such as Barangka in Marikina, Pasig areas near Rosario, central parts of the city of Manila (Blumentritt, Maceda, España, etc.), and parts of Roxas Boulevard in Pasay.
The NCR is practically sandwiched between Manila Bay, facing the China Sea on the west side and Laguna Lake on the southeast. Another factor to consider is the northeastern part bordering the province of Rizal.
In recent years, the mountainsides there have practically been denuded and logged to the ground, and residents in the lower parts of Antipolo City near Marikina have experienced damaging floods due to the accumulated rainwater from Rizal flowing into the river.The Angat Dam and the Pampanga river basins are also hazards to Metro Manila if a super typhoon of the same scale as Yolanda hits. In 2012, disaster management official Edgardo Ollet admitted that the dam “has cracks and needs major repairs”.
One can imagine that the combined force of incessant raining and a highly possible super typhoon is all it would take, and a deluge of epic proportions is just waiting to happen. Meanwhile Dr. Mahar Lagmay of DOST’s Project Noah was also asked by Robles, and he was positive that another super typhoon can happen in the near future. Dr. Lagmay even put it this way: “It’s Russian roulette”. It may not hit now, or any time this week, or the next, but the chances are very high that it can and will happen. Scientists do not need to reiterate those facts to us, as it is already evident in our history as a country: tropical storms are regular occurences. The sad truth is that we as a society have not learned so much from past disasters. As philosopher George Santayana would put it, those who cannot remember the past are condemned to repeat it.
Lessons In Foresight
Pecier Decierdo, a physics teacher who works for Mind Museum and science advocacy director for civil organization Filipino Freethinkers, has provided pointers that the public should always keep in mind when it comes to handling disasters. He stated, “More storms make landfall on the Philippines than on any other large country on Earth.”
This one fact demands that the science curriculum in the country should be tailored to produce basic education graduates who understand how tropical storms roll.” According to him, allowing an inadequately informed population to live in a storm-prone country is a massive inhumanity.
A public dialogue on disaster management should be top priority, so that people will be more capable and well-informed in handling the effects of natural disasters in our lives, rather than wait for government to dictate disaster measures. Decierdo remarked, “We should talk about the weather more”. It is known that the country has an insufficient number of meteorologists, and that the public does not regard due status to meteorologists and weather scientists, which results to having underpaid and overworked PAGASA employees.
Underpaid weather specialists and undermanned and ill-equipped weather stations result to inaccurate weather forecasting, which lead to deaths and losses that could otherwise have been prevented.
Using 2009’s Ondoy devastation as basis, we can expect that a Haiyan-scale super storm will bring in not just the strongest winds, but the force of floodwaters rushing in and submerging two-story buildings. Business and commerce in the metropolis will definitely be halted. Makati’s main thoroughfares would be clogged, and being a neighbouring city to flood-prone Pasay, it just makes it worse.
Roxas Boulevard, site of Manila’s significant commercial activities and facing Manila Bay, would be the one of the most damaged for obvious reasons. Metro Manila is located in a catchbasin between Manila Bay and Laguna Lake, which means that there is no exit for excess water pouring in from both sides. According to urban planner and master architect Paolo Alcazaren, most of the drains constructed since the Spanish period have either been lost, covered up, or clogged with garbage.
A super typhoon hitting Metro Manila will definitely paralyze the country’s economy,because it will be more than the sum of the past typhoons of the last five years.
This doesn’t mean that we should just be fatalistic and embrace the apocalyptic end times, because something can actually be done.
This is where disaster experts come in. In an interview with Rappler’s Marites Vitug, Kathryn Hawley of Asia Foundation advises that it’s best to prepare for a worst-case scenario and hope that it doesn’t happen. Measures such as stockpiling of water and food, strategic assigning of resources, land use regulations, low-cost housing programs, public awareness campaigns and poverty reduction strategies can help absorb the shocking blow of an imminent catastrophe.
A super typhoon hitting Metro Manila will definitely paralyze the country’s economy,because it will be more than the sum of the past typhoons of the last five years. If not a super typhoon, the threat of the Marikina Fault System is imminent. Combine that with mounting government negligence, festering corruption, and lack of public preparedness. It is a tragedy waiting to happen, and we cannot just stand by and ignore it. It is time to learn by foresight rather than hindsight.
Disaster readiness is the only way to reduce the “what ifs?”.
