Are our Kids Safe from Earthquakes? | Dr. Kit Miyamoto | TEDxCSUS


past ten years we lost 750,000 people

past ten years we lost 750,000 people 750,000 people by earthquakes it is

750,000 people by earthquakes it is

750,000 people by earthquakes it is actually much more than the combined the

actually much more than the combined the

actually much more than the combined the hurricane death to the flood and drought

hurricane death to the flood and drought

hurricane death to the flood and drought and everything combined it’s the most

and everything combined it’s the most

and everything combined it’s the most lethal weapon that they actually and so

lethal weapon that they actually and so

lethal weapon that they actually and so that’s our job to actually see it that

that’s our job to actually see it that

that’s our job to actually see it that what what happened out there and how we

what what happened out there and how we

what what happened out there and how we can actually the reduce this risk now

can actually the reduce this risk now

can actually the reduce this risk now this picture here is a taking from

this picture here is a taking from

this picture here is a taking from Mexico City which we had earthquake in

Mexico City which we had earthquake in

Mexico City which we had earthquake in September we lost almost 400 people the

September we lost almost 400 people the

September we lost almost 400 people the earthquake had destroyed about 44

earthquake had destroyed about 44

earthquake had destroyed about 44 buildings and damaged 3,000 to 4,000

buildings and damaged 3,000 to 4,000

buildings and damaged 3,000 to 4,000 buildings up there and here’s a picture

buildings up there and here’s a picture

buildings up there and here’s a picture of it you’re gonna see that this is the

of it you’re gonna see that this is the

of it you’re gonna see that this is the old concrete structure and this is

old concrete structure and this is

old concrete structure and this is you’re gonna see that down the column

you’re gonna see that down the column

you’re gonna see that down the column said buckling there and started cracking

said buckling there and started cracking

said buckling there and started cracking it and here’s collapse that’s how the

that’s where the toward the started

that’s where the toward the started collapsing like that so in the Mexico

collapsing like that so in the Mexico

collapsing like that so in the Mexico any buildings built prior to 1985 it’s

any buildings built prior to 1985 it’s

any buildings built prior to 1985 it’s actually pretty dangerous because they

actually pretty dangerous because they

actually pretty dangerous because they had an earthquake in 1985 and a building

had an earthquake in 1985 and a building

had an earthquake in 1985 and a building code changed quite a bit before that it

code changed quite a bit before that it

code changed quite a bit before that it was very dangerous and this is one of

was very dangerous and this is one of

was very dangerous and this is one of our buildings we went in so as the

building collapse it was like this used to be a eight story building now down to

to be a eight story building now down to

to be a eight story building now down to become a two-story and you can kind of

become a two-story and you can kind of

become a two-story and you can kind of see the lay of a concrete that’s used to

see the lay of a concrete that’s used to

see the lay of a concrete that’s used to be a floor now so this is a built before

be a floor now so this is a built before

be a floor now so this is a built before 1985 so it’s a known dr. concrete

1985 so it’s a known dr. concrete

1985 so it’s a known dr. concrete structures that’s why it’s collapse like

buildings that’s so dangerous we get to

buildings that’s so dangerous we get to something about it so couple years ago

something about it so couple years ago

something about it so couple years ago we formed a nonprofit organization

we formed a nonprofit organization

we formed a nonprofit organization called Miyamoto global disaster relief

called Miyamoto global disaster relief

called Miyamoto global disaster relief and it’s organizations of focus on make

and it’s organizations of focus on make

and it’s organizations of focus on make it safe for the schools we worked in the

it safe for the schools we worked in the

it safe for the schools we worked in the schools in Haiti and Nepal and in many

schools in Haiti and Nepal and in many

schools in Haiti and Nepal and in many other places come I think you can be
