A University of Ottawa scientist will travel to Chile next week to search for lessons that Canadian engineers and emergency planners can draw from that country\u2019s 8.8-magnitude earthquake.<\/p>\n

Professor Murat Saatcioglu, one of Canada\u2019s foremost earthquake engineers, will lead a team of 10 scientists to Chile on Tuesday.<\/strong><\/span><\/p>\n

They\u2019ll examine buildings and bridges that collapsed in the quake to understand why they failed \u2014 and whether similar structures in Canada could withstand the same seismic shaking.<\/p>\n

The questions are of particular concern on Canada\u2019s Pacific coast, which has a geological fault similar to the one that produced Chile\u2019s massive quake.<\/p>\n

Both regions lie in \u201csubduction zones,\u201d where one tectonic plate grinds and pushes against another on top of it. A sudden slip along the fault can lift the overriding plate, creating what scientists call a \u201cmegathrust earthquake.\u201d<\/p>\n

Such earthquakes can displace huge amounts of ocean water, spawning a tsunami.<\/p>\n

\u201cThe reason we wanted to go to Chile is that the fault mechanism that led to this earthquake is very similar to the subduction zone we have just west of Vancouver Island,\u201d Saatcioglu said in an interview. \u201cAnd the type of ground shaking is likely to be very similar since it\u2019s a similar type of fault mechanism.\u201d<\/p>\n

Chile presents a compelling case study, and not only because its quake produced the kind of shaking expected to hit Vancouver and Victoria in the future. It also has in place similar building standards to those in Canada.<\/p>\n

\u201cHopefully we\u2019ll learn a lot, since we\u2019ll be inspecting buildings and bridges which are designed \u2014 unlike Haiti \u2014 to current standards,\u201d Saatcioglu said.<\/p>\n

Haiti suffered more physical damage than Chile in a smaller quake because so many of its buildings were made of concrete diluted with sand or reinforced with poor steel.<\/p>\n

The Canadian research team, sponsored by the Canadian Association for Earthquake Engineering, includes structural engineers, seismologists, tsunami experts and bridge engineers. They\u2019re scheduled to travel to Santiago, Concepci\u00f3n and tsunami-damaged coastal towns during eight days of research.<\/p>\n

The earthquake in Chile occurred in the same subduction zone that spawned the largest quake of the 20th century. On May 22, 1960, a magnitude-9.5 earthquake killed 1,655 people and generated a tsunami that devastated Hawaii, Japan and the Philippines.<\/p>\n

Subduction zones give rise to mountain ranges and volcanic activity, but also produce the world\u2019s largest earthquakes.<\/p>\n

In the subduction zone of the Pacific Northwest, the Juan de Fuca tectonic plate is sliding under the much larger North American plate. Scientists know the stress building in the zone will eventually cause the plates to slip, triggering a high-magnitude earthquake, but they can\u2019t predict when it will happen.<\/p>\n

Geological deposits suggest large earthquakes have hit Canada\u2019s Pacific coast 13 times in the past 6,000 years.<\/p>\n

According to Natural Resources Canada, the last megathrust earthquake struck on Jan. 26, 1700, producing a 1,000-kilometre rupture along the Cascadia fault from Vancouver Island to northern California. It triggered a tsunami that swept across the Pacific.<\/p>\n

While Ottawa is not at risk for a megathrust earthquake, it does sit in a seismically active valley. Dozens of earthquakes occur each year in eastern Ontario and western Quebec, but most are too mild to be felt.<\/p>\n

Earth scientists consider the risk of a major quake here to be moderate: there is a 10-per-cent chance an earthquake will be strong enough to damage buildings in Ottawa during the next 50 years. Those areas with thick pockets of Leda clay under them, including parts of Carp and Orl\u00e9ans, are likely to experience more shaking and damage in a major temblor.<\/p>\n

5 Mart sabahi gazetede bir tek Amerika’daki Ermeni meselesi oylamasi haberlerini aradigim icin Murat Saatcioglu’nun belki de ayni derecede \u00f6<\/span>nemli haberini kacirmisim. Ertesi gun kizimin g\u00f6<\/span>stermesi sayesinde okudum.<\/p>\n

Ottawa Citizen gazetesinin Murat Beyin calismalarini ve basarilarini birinci sayfada haber yapmasinin uzerinden daha bir yil bile gecmeden Prof. Saatcioglu yeniden gazetede cok buyuk bir resim ve cok buyuk bir makale ile \u00f6<\/span>n planda.<\/p>\n

Bu haber neden Ermeni meselesi kadar onemli? Bence, Murat Bey, tum yuksek statusu ve medyada sik sik yer alan basarilarinin yani sira toplum hizmetlerinde calisan ve toplum adina acik acik konusan bir kisi oldugu icin. Murat Bey bu \u00fc<\/span>n\u00fc<\/span> ve kredileri ile bir milletvekilini, bir bakani ziyarete gittiginde soyledigi sozleri dikkatle dinliyorlar.<\/p>\n

Cok basarili, cok degerli pek cok profesorumuz var. Kanada universiteleri Turk profesorleri ile dolu. Daha yeni okudum, Vancouver’da 3 Turk profesorune fahri doktara unvanlari verilmis. Umarim diger profesorlerimiz de Murat Saatcioglu kadar toplum bilincine sahip ve duyarli kisilerdir ve umarim onlar da ayni sekilde toplumun cikarlari icin basari ve unvanlarini kullanarak, etkili politikaci ve basin mensuplari ile konusuyorlar, derdimizi anlatiyorlardir. Bir gazeteye, bir bakana boyle unvanlara sahip Turklerimizin yazdigi mektuplarin degerine paha bicilemez.<\/p>\n

Lale<\/p>\n
