With 325 years between coastal B.C. and its last subduction or megathrust earthquake, typical best describes 2024, says a seismologist with Natural Resources Canada.

Southwest B.C., where tectonic plates collide, is Canada香蕉视频直播檚 hotspot, seeing more than 1,200 earthquakes last year. Several were felt and most were offshore along the active faults.

香蕉视频直播淭here香蕉视频直播檚 always something going on around here. We typically see tiny earthquakes each and every day people aren香蕉视频直播檛 feeling,香蕉视频直播� said John Cassidy.

It香蕉视频直播檚 an average number for the region, with most small or far enough away to not even be felt. Two deep quakes stand out because they were widely felt late in the year off Sidney and Tsawwassen.

On Sept. 26, a 3.8-magnitude earthquake hit nearly 60 km deep 香蕉视频直播� contributing to why thousands reported feeling it despite its weakness. It was lightly felt in Vancouver and Victoria, according to Earthquakes Canada, including up to the tip of the Saanich Peninsula and as far as Nanaimo to the north and Sooke to the west.

Eight days later, a similar quake was felt across the southwest, centred 18 km west of Tsawwassen.

香蕉视频直播淚t香蕉视频直播檚 pretty typical. These deep earthquakes are common in the area,香蕉视频直播� Cassidy said.

香蕉视频直播淏ut it is a complex region because we have different types of earthquakes,香蕉视频直播� he added. 香蕉视频直播淲e have an ocean plate that is moving toward us four to six centimetres per year, that香蕉视频直播檚 about how fast your fingernails grow.香蕉视频直播�

Adding up to four to six metres of movement in 100 years, the plates are locked together, moving towards the area from the west. All the while, they're 香蕉视频直播渟toring energy for one of these big subduction earthquakes.香蕉视频直播�

While tiny earthquakes happen nearly every day, subduction earthquakes occur in the subduction zone, where two tectonic plates collide and one is forced beneath the other. The last was a magnitude 9 that struck in the year 1700.

Somewhere in the middle in terms of magnitude are the surface-to-30-km-deep earthquakes in the crust, like the two felt late last year, but closer to the surface. Those in the 4- to 6-magnitude range are capable of causing damage and occur every decade or so on the south coast.

None of them come with a warning.

香蕉视频直播淭here香蕉视频直播檚 no signals or indications of when an earthquake will happen. We do have earthquake early warning systems in place now,香蕉视频直播� Cassidy said.

The Earthquake Early Warning system, developed by Natural Resources Canada, became operational in B.C. in spring 2024. Almost 100 core stations work together to monitor for powerful earthquakes. Those larger than magnitude 5 and close enough to communities with systems in place will trigger the public system alert, similar to an Amber Alert.

香蕉视频直播淒epending on how far away the earthquake is, it really controls how much warning time you have. For one of the deep earthquakes, the one off Sidney in October, you might have a five- or 10-second warning here in Victoria,香蕉视频直播� Cassidy said.

The systems take advantage of the fact modern information sharing is even faster than the speedy three to four kilometres per second waves of an earthquake.

Being prepared ahead is just as critical as those seconds to minutes warning.

They include simple steps like keeping shoes and a flashlight by the bed, securing heavy wall hangings and bookshelves, and having the basic emergency kits and grab-and-go bags ready for any emergent situation.

These tips, for the CRD specifically, can be found at .

While a megathrust could be in nature香蕉视频直播檚 works, the region is better prepared than ever, Cassidy said. There have been leaps and bounds in equipment and inter-agency collaboration, more and deeper data on the regular both around the world and locally and even building codes developed with earthquakes in mind.

香蕉视频直播淭he science is advancing really quickly,香蕉视频直播� he said. 香蕉视频直播淭hings are getting better all the time.香蕉视频直播�
