T&T Earthquake Thread

[pugboy]

We really not seeing any footage from venezuela

[hydroep]

me eh know bout allyuh, but i rel jittery and can't sleep since last night. And i swear i only feeling some very low frequency waves now and then, just waiting for the place to just start to tremor and shear diagonally all of a sudden. I was ready to dead yesterday when the 2nd shake got worse after the 1st one wasn't stopping. You know that terrible sound the walls and roof makes and everything swaying left to right? Hearing it in my subconscious all the time now. Feeling phantom movements all the time.

This is the new normal...We have grown accustomed to low 4s and 5s etc but this is the new normal now and should be a good wake up call.

This whole experience has me uneasy especially the length of time it lasted, the damage it caused and the fact that it occured all the way in Venezuela and with such depth...

People on edge and imaginations working overtime. Twice today I asked somebody: "yuh feel dat?" (after the aftershock) and others have related similar experiences. One person said they felt their staircase was moving while making their way down this morning...

Trinidad Earthquakes - 32 tremors in 24hrs

Loop - The University of the West Indies Seismic Research Centre (UWI-SRC) says Trinidad and Tobago is lucky to have sustained such little damage following Tuesday's 6.9 magnitude earthquake.

At 5:31 pm on Tuesday, T&T was hit by the first quake followed by 32 aftershocks which include a 6.0 magnitude tremor which struck at 9:27 am on Wednesday.

The details were provided by UWI-SRC Director, Professor Richard Robertson, who was speaking at the SRC's office in St Augustine on Wednesday evening.

He said the stats were accurate up to 4 pm on Wednesday 22nd August 2018.

Had a small crack on d wall outside for a couple years now, ting look like it open up and spread oui

So ..how do we reinforce / strengthen a building for earth quakes? Obviously you can't build over and start from scratch...unless its an old shack..

Strange enough....plenty ah dem shacks stand up strong eh

[pugboy]

if footing is stable and small enough so whole thing shakes as one it usually better than a shack that was put up in sections and other parts added on later to different footing

that is the importance of a proper foundation which is locked in with the ring beam at top

a lot of those cracked walls in commercial buildings we are seeing are the non load bearing partition walls between steel columns which were bricks simply laid on the cast decking pan floor

Pass through Picadilly while exiting POS this morning. At least the roadside properties looked normal. Even the sketchy ones.

Strengthening would be adding structural members to an existing building to move the forces from the center of a beam from an upper floor to the base of a column of the floor beneath. Walls can be reinforced and tied directly into nearest columns also.

One of the biggest contributors to earthquake damage is irregular construction; spans of long or different lengths, disconnected footings, loading that doesn't go directly to a foundation, building that do not have a broad base with respect to their height, etc.

I aint know where it was mentioned before cuz this ched too damn long..but

Soon from now Port of Spain gonna be a text book case study on liquefaction.

I poopose Chaguanas to be the next capital.

Wood-frame construction advantageous in areas prone to seismic activity
February 19, 2014
Structures + Buildings

Wood-frame construction is substantially lighter than other types of construction and has a high strength-to-weight ratio. As a result, properly designed and built wood-frame structures perform well during seismic activity.

Some 1,400 years ago, tall wood-framed pagodas in Japan were built to 19 stories tall. In spite of the area’s high seismic activity – including the 6.8 magnitude Hyogo-ken Nambu earthquake in 1995 that caused widespread damage – these structures still stand today.

The U.S. Geological Survey estimates more than a million earthquakes occur across the world each year. None can be prevented, but sound design and construction can minimize structural damage. Wood-framed structures, such as the pagodas in Japan, perform exceptionally well against lateral forces created by seismic activity. Years of building code development have proven that wood-frame construction meets and in many cases exceeds the most demanding seismic design requirements.

Wood has inherent characteristics that offer advantages over concrete, masonry and steel building designs. As a result, wood can be an ideal material in areas prone to seismic activity.

Light weight
Most earthquake damage is caused by seismic waves that force the ground to move. When the ground motion is strong enough, it causes the building’s foundation to shake. Earthquake forces are proportional to a structure’s mass, so heavy steel and concrete structures experience greater forces. Wood-frame construction is substantially lighter than other types of construction and has a high strength-to-weight ratio. As a result, properly designed and built wood-frame structures perform well during seismic activity.

Ductility
Wood-frame structures have numerous nailed connections and joints. This provides inherent ductility – much more so than most rigid masonry and concrete systems. Wood-frame buildings can flex, absorbing and dissipating energy when subjected to sudden earthquake forces.

Redundancy
Similarly, sheathing and finishes attached to wood joists and studs provide redundant load paths for earthquake forces. These numerous small connections and load paths dissipate seismic forces. Should some connections be overloaded or fail, adjacent connections will usually provide alternate load paths and help avoid collapse. This said, systems with poorly designed load paths will be prone to damage or even collapse, regardless of the material used.

Strength and stiffness
An earthquake’s lateral forces tend to distort building walls, causing them to rack. Shearwalls in wood construction provide necessary racking resistance. The stiffness and resistance of walls can be augmented in areas prone to strong earthquakes by increasing the thickness of structural panels, stud size, and number or size of nails.

Connectivity
Securely connecting a structure’s walls, floors and roof framing make it a single, solid unit, which is critical to withstanding earthquake forces. All structural elements must be anchored to the building’s foundation to resist racking, sliding and overturning during an earthquake. Standard connections and tie-downs manufactured for high-load designs make this quite simple.

Seismic design
The key to any seismic design is ensuring good behavior, not sufficient brute strength. This is particularly true for wood-frame structures, which are assigned a high ductility factor. While many wood-frame buildings inherit redundancy and ductility through the multiple load paths afforded by their very architecture, wood frame is increasingly used in wide, open structures such as highly glazed custom homes, schools and commercial buildings. North American timber codes are not particularly clear on this issue, but the principles of capacity design must be applied to the design of wood-frame structures as they would for any other structure.

Wood-frame systems, with solid design and construction, are proven to withstand the effects of powerful earthquakes. Wood’s versatility and structural performance offer a range of additional benefits and make it ideal for a number of building types and geographies.

what location? the west got it stronger apparently

I am hearing ppl saying that these earthquakes mean 'the big one' is next.

4.0 mag. aftershock at 6:44am Thursday

37 aftershocks since Tuesday's 6.9 mag.

That depends on what "the big one" is. Earthquakes don't just happen off of vaps....These plates have been moving this way for centuries so there is history showing how the plates moved and the sort of earthquakes that occured in the past. A good way to tell what sort of earthquakes you may experience is by revisiting past events. Japan, China etc have been suffering devastating earthquakes and tsunamis for hundreds and even thousands of years..

Remember that the epicenter of this earthquake was in Venezuela, so let's see what sort of earthquakes affected the region in the past and how powerful they were.

I personally don't believe in a "Big one" cause "Big" is pretty subjective. Not all regions are going to suffer big quakes. The plates still act and behave in very precise manners. It's not like you gonna get a massive earthquake in an area not seismologically active etc.

Any words from this prime minister yet?!?! so he not doing anything to ensure our safety since the entire world under threat?

Any words from this prime minister yet?!?! so he not doing anything to ensure our safety since the entire world under threat?

Earthquakes are a worldwide problem. And so is crime. Drink up.

[hydroep]

Sh!tkicker MIA again at a time the country is looking for reassurance from the leadership...nothing new there.

He probably not saying anything because there's no profit in it for him...yet. If the big one hit most likely some party financier(s) go get contracts to rebuild the country, and then he go spin it to say how people getting jobs and t'ing.

Grate is the Pee oN deM..

Attic: Make your earthquake claims early
Carla Bridglal 3 Hrs Ago

Damage or loss caused by earthquakes are covered under homeowner’s insurance but there are deductibles based on the company, the Association of TT Insurance Companies (Attic) said. For vehicles, the association said, since falling debris is classified as an “act of God” the owner of the property or the insurer can’t be held responsible, so the insurance policy for the car then comes into play. “Hopefully the person has comprehensive cover,” Attic said.

The association advised policyholders to call their insurance agents or brokers as soon as possible to make claims. Losses sustained over the 72-hour period since last Tuesday’s initial 6.9 earthquake will be treated as one claim, Attic said. This includes Wednesday’s 5.8 aftershock. ”We encourage clients to check their policy documents with respect to the terms and conditions regarding the deductible or excess,” Attic said.

The first step to make a claim is to complete a claim form. Along with that, at minimum, customers need to provide photographs or any other information to support claim, along with any other information required by the insurer, including estimated for repairs, if possible. “We encourage clients to check their policy documents with respect to the terms and conditions regarding the deductible or excess,” Attic said. Deductibles and excesses are the out of pocket cost the insured needs to put up before the insurance coverage kicks in.

“We are thankful that the country has been spared any major devastation. We take this opportunity to remind the public of the importance of having proper coverage against these and other risks,” Attic said.

The association said it could not give an estimate on the losses claimed just yet, since that data will be collected over the coming weeks.
