Developers maximize this.)</p><p>The architect noted that very tall buildings &quot;sway by design...like pine trees&quot; to withstand the impact of earthquakes. </p><p>He noted that under the JICA study, a massive quake would more likely destroy low-rise buildings while only 2 percent of tall buildings would collapse. </p><figure class="op-interactive"><iframe allow="autoplay; fullscreen" frameBorder="0" height="100%" id="ivsplayer01" scrolling="no" src="https://player.ivideosmart.com/ivsplayer/v4/dist/html/iframe-src.html?iframeid=ivsplayer01&amp;key=e8c22c015ca9eafa76f1e3edfa03c603&amp;spid=3001339&amp;vid=1386093" width="100%"></iframe></figure><div class="iwantbar">Watch more News on <a href="https://www.iwanttfc.com/#!/browse/Genres/News/tag_id_genres/id_news" target="_blank">iWantTFC</a></div><p>Palafox said one solution he implements in his own firm is to instruct structural engineers &quot;to design [the buildings] 10 percent over and above the building code, structural code and other engineering codes.&quot;</p><p>He cited as an example the first 5 towers of Rockwell, which stand 30 meters apart compared to only 1 meter under the building code. </p><p>One Palafox-designed building, the Bed and Brew Hostel in Siargao, also withstood the impact of Super Typhoon Odette, despite causing P20 billion worth of damage on the island, he said. </p><p>Palafox said that under the JICA study, a massive quake would be more dangerous to informal settlers whose houses are built with light materials. &quot;Mas maraming mapinsala [sa mga] informal settlers kasi dikit-dikit ang mga bahay nila,&quot; he said. </p><p>(Informal settlers would suffer more damage because their houses are crowded together.)</p><p>Another danger that needs to be addressed, he said, is the building of subdivisions on top of faultlines. His solution? &quot;Homes built on top of faultlines should be demolished and set back 5 meters from the faultline,&quot; he said. </p><p>He also cited the importance of open areas in the city, which function as the &quot;lungs&quot; of a city and serve as evacuation areas during an earthquake. </p><p>He also encouraged design professionals, contractors, architects, engineers and project managers to expose corruption, which leads to poor quality of structures that collapse during earthquakes. He cited as an example one contractor who allegedly had to give 28 percent in kickbacks so he could be paid. </p><p>At least 12 people including contractors were detained by Turkish police after 6,000 buildings collapsed during the Feb. 6 earthquake. </p><ul class="op-related-articles">	<li><a href="https://news.abs-cbn.com/overseas/02/11/23/turkey-detains-12-over-collapsed-buildings-after-quake-report">Turkey detains 12 over collapsed buildings after quake: report</a></li></ul><p>&quot;Dapat magsumbong na sila kung may involved na corruption kasi it&#x27;s 90 percent less expensive to address the hazards before they become disasters...So we can save more human lives,&quot; he said. </p><p>(They should report corruption.)</p><figure class="op-interactive"><iframe allow="autoplay; fullscreen" frameBorder="0" height="100%" id="ivsplayer01" scrolling="no" src="https://player.ivideosmart.com/ivsplayer/v4/dist/html/iframe-src.html?iframeid=ivsplayer01&amp;key=e8c22c015ca9eafa76f1e3edfa03c603&amp;spid=3001339&amp;vid=2470509" width="100%"></iframe></figure><div class="iwantbar">Watch more News on <a href="https://www.iwanttfc.com/#!/browse/Genres/News/tag_id_genres/id_news" target="_blank">iWantTFC</a></div>
