The earthquake that ravaged Turkey and Syria this week offers both lessons and warnings for people in British Columbia as images emerge of the human devastation and costly damage, Canadian seismology experts say.

John Clague, a professor emeritus in the Earth Sciences department at Simon Fraser University, said there is much to learn from the latest quake.

Clague said that while 91裸聊视频渢he big one could come any minute,91裸聊视频 the time frame for such an event in geological terms makes it hard to imagine for most people, whether they91裸聊视频檙e in an earthquake-prone zone or not.

Major seismic events occur about every 500 years, he said, making them rare enough for most people to worry more about the day-to-day dangers of driving a car, for example.

91裸聊视频淚91裸聊视频檓 sure you could have talked to the people living in one of those cities or towns in Turkey and they would have said, 91裸聊视频榳ell, yeah, we know we live on our fault zone, but, you know, we haven91裸聊视频檛 had a giant earthquake in hundreds of years, so why should we worry about it?91裸聊视频91裸聊视频

Clague said both individuals and governments can fall into the same trap of short-term thinking since the threat of earthquakes and other natural disasters seems distant in terms of time and space.

However, Clague credited the provincial government for investing in seismic upgrades of regional transportation infrastructure and schools, for example, though he admitted to thinking such investments are 91裸聊视频渘ever enough.91裸聊视频

91裸聊视频淚 do appreciate that governments have other demands on their agenda like the opioid crisis and homelessness and we don91裸聊视频檛 have unlimited amounts of public moneys to deal with all the problems we face,91裸聊视频 Clague said. 91裸聊视频淚t91裸聊视频檚 a balancing act.91裸聊视频

Clague said cities like Vancouver are fortunate to have modern building codes that are regularly revised and updated, while also being far away from the likely epicentre of the next major earthquake to avoid the 91裸聊视频渨orst case scenario91裸聊视频 damage seen after 7.8 and 7.5 magnitude quakes in Turkey and Syria this week.

91裸聊视频淪yria is quite a ways away from the epicentre of either of those big earthquakes, and they had buildings collapsing there,91裸聊视频 Clague said. 91裸聊视频淪o, that shouldn91裸聊视频檛 happen, you know, in a country that has proper construction practices in earthquake zones.91裸聊视频

He added that he doesn91裸聊视频檛 like to frighten people with dire predictions, but urges people to be prepared for earthquakes even though they91裸聊视频檙e rare and Vancouver is somewhat insulated from the worst-case scenario seen in Turkey and Syria.

91裸聊视频淚 just reinforce the fact that even though Vancouver hasn91裸聊视频檛 been damaged by an earthquake, you know, Vancouver91裸聊视频檚 only 130 years old or 140 years old,91裸聊视频 he said. 91裸聊视频淚t91裸聊视频檚 always a good idea to be prepared and being prepared doesn91裸聊视频檛 really require that much effort.91裸聊视频

For Shariah Alam, a professor in the University of British Columbia91裸聊视频檚 School of Engineering, earthquakes reveal whatever deficiencies there may be in a region91裸聊视频檚 building and transportation infrastructure.

In Turkey and Syria, for instance, most of the damage and destruction likely stemmed from how old buildings, bridges, and roads were at the time of the quake, he said.

Canada, he said, has 91裸聊视频渓earned lessons from various events91裸聊视频 that have seen the country91裸聊视频檚 building codes mature and modernize thanks to a 91裸聊视频渃onstant effort to improve our design code.91裸聊视频

However, older buildings and infrastructure built before the 1970s remains particularly vulnerable, Alam said, pointing to a 2013 study commissioned by the Insurance Bureau of Canada that estimated $75 billion in potential damage in B.C. in the event of a 9.0 magnitude earthquake.

Earthquakes Canada said the Cascadia megathrust earthquake with a magnitude of 9 hit the west coast of North America on Jan. 26, 1700, sending a massive tsunami across the Pacific that reached Japan.

Alam said governments of all levels have to step-up efforts to not only educate people, but also take 91裸聊视频渟trong initiatives91裸聊视频 to identify vulnerable infrastructure and prioritize repairs and retrofitting to ensure scenarios like that in Turkey and Syria don91裸聊视频檛 happen here.

91裸聊视频淚 think it requires a substantial amount of effort, energy, (and) funding,91裸聊视频 he said.

Last month, the B.C. and federal government jointly announced the province is ramping up an early earthquake detection system in 91裸聊视频渉igh seismic risk areas.91裸聊视频

The national earthquake early warning system already has several hundred sensors overseen by Natural Resources Canada and the new initiative would see up to 50 additional sensors that would go online in 2024.
