hi everybody

hi everybody I don’t think I need to say much more

I don’t think I need to say much more

I don’t think I need to say much more than that it was very good introduction

than that it was very good introduction

than that it was very good introduction it’s an easy topic what I want to talk

it’s an easy topic what I want to talk

it’s an easy topic what I want to talk about it has to do with extreme events

about it has to do with extreme events

about it has to do with extreme events that we cannot predict and in recent

that we cannot predict and in recent

that we cannot predict and in recent years we know that extreme natural

years we know that extreme natural

years we know that extreme natural hazards have been extremely destructive

hazards have been extremely destructive

hazards have been extremely destructive and more frequent just 2016 was the

and more frequent just 2016 was the

and more frequent just 2016 was the worst year in natural hazard losses with

worst year in natural hazard losses with

worst year in natural hazard losses with estimates on the order of more than one

estimates on the order of more than one

estimates on the order of more than one hundred and fifty billion dollars from

hundred and fifty billion dollars from

hundred and fifty billion dollars from the Swiss reinsurance one of these

the Swiss reinsurance one of these

the Swiss reinsurance one of these events that I will be referring to is

events that I will be referring to is

events that I will be referring to is the Ecuador earthquake that happened in

the Ecuador earthquake that happened in

the Ecuador earthquake that happened in April of 2016 of a magnitude 7.8 but

April of 2016 of a magnitude 7.8 but

April of 2016 of a magnitude 7.8 but more than the damage what we have

more than the damage what we have

more than the damage what we have learned is that extreme natural hazards

learned is that extreme natural hazards

learned is that extreme natural hazards can cause tremendous losses in terms of

can cause tremendous losses in terms of

can cause tremendous losses in terms of downtime of things not working and an

downtime of things not working and an

downtime of things not working and an example in the city where I live and

example in the city where I live and

example in the city where I live and work in New York City was the 2012

work in New York City was the 2012

work in New York City was the 2012 hurricane sandy where the financial

hurricane sandy where the financial

hurricane sandy where the financial damage was more than seventy billion

damage was more than seventy billion

damage was more than seventy billion dollars locally owned losses of things

dollars locally owned losses of things

dollars locally owned losses of things not working essentially we did not

not working essentially we did not

not working essentially we did not really have any structural damage but we

really have any structural damage but we

really have any structural damage but we had flooding that prevented us from

had flooding that prevented us from

had flooding that prevented us from functioning and globally of course there

functioning and globally of course there

functioning and globally of course there was a tremendous effect because the Wall

was a tremendous effect because the Wall

was a tremendous effect because the Wall Street shut down for two days so these

Street shut down for two days so these

Street shut down for two days so these are issues that affect an infrastructure

are issues that affect an infrastructure

are issues that affect an infrastructure that is already age beyond the design

that is already age beyond the design

that is already age beyond the design life that we have made it as designers

life that we have made it as designers

life that we have made it as designers which is typically 50 years it’s

which is typically 50 years it’s

which is typically 50 years it’s trembling as it is without any

trembling as it is without any

trembling as it is without any earthquake or wind or other loads and we

earthquake or wind or other loads and we

earthquake or wind or other loads and we know that just to maintain the rapid

know that just to maintain the rapid

know that just to maintain the rapid increase of our population if we wanted

increase of our population if we wanted

increase of our population if we wanted to use this existing infrastructure

to use this existing infrastructure

to use this existing infrastructure without any natural hazards hitting it

without any natural hazards hitting it

without any natural hazards hitting it on top of it we need six trillion

on top of it we need six trillion

on top of it we need six trillion dollars a year and we are only investing

dollars a year and we are only investing

dollars a year and we are only investing three so we have an issue so what do we

three so we have an issue so what do we

three so we have an issue so what do we as engineers have in certain tools and

as engineers have in certain tools and

as engineers have in certain tools and usually these tools are codes and codes

usually these tools are codes and codes

usually these tools are codes and codes have existed for many many years

have existed for many many years

have existed for many many years tracing back thousands of years ago in

tracing back thousands of years ago in

tracing back thousands of years ago in Mesopotamia in the Code of Hammurabi

Mesopotamia in the Code of Hammurabi

Mesopotamia in the Code of Hammurabi that essentially said that if a builder

that essentially said that if a builder

that essentially said that if a builder builds a house and this house is

builds a house and this house is

builds a house and this house is destroyed

destroyed

destroyed after an earthquake or for whatever

after an earthquake or for whatever

after an earthquake or for whatever other reason then this builder shall be

other reason then this builder shall be

other reason then this builder shall be put to death and the same for his child

put to death and the same for his child

put to death and the same for his child if the child of the owner is dead

if the child of the owner is dead

if the child of the owner is dead very straightforward very scary I’m sure

very straightforward very scary I’m sure

very straightforward very scary I’m sure it was quite convincing right now we

it was quite convincing right now we

it was quite convincing right now we have evolved from that and we can

have evolved from that and we can

have evolved from that and we can calculate probabilities of this maximum

calculate probabilities of this maximum

calculate probabilities of this maximum earthquake happening and how big it’s

earthquake happening and how big it’s

earthquake happening and how big it’s going to be and we have put all that in

going to be and we have put all that in

going to be and we have put all that in codes and the most recent code from the

codes and the most recent code from the

codes and the most recent code from the American Society of Civil Engineers

American Society of Civil Engineers

American Society of Civil Engineers gives actual probabilities so if you are

gives actual probabilities so if you are

gives actual probabilities so if you are now in Mesopotamia you want to build the

now in Mesopotamia you want to build the

now in Mesopotamia you want to build the same house then you know that you are

same house then you know that you are

same house then you know that you are accepting our society as a code that you

accepting our society as a code that you

accepting our society as a code that you will have a 10% probability of this

will have a 10% probability of this

will have a 10% probability of this house collapsing if that big earthquake

house collapsing if that big earthquake

house collapsing if that big earthquake happens you are also accepting a 25%

happens you are also accepting a 25%

happens you are also accepting a 25% probability that you will be hurt or

probability that you will be hurt or

probability that you will be hurt or died in that big earthquake

died in that big earthquake

died in that big earthquake why do we have this boundaries it’s a

why do we have this boundaries it’s a

why do we have this boundaries it’s a matter of economics because we cannot

matter of economics because we cannot

matter of economics because we cannot build the perfect house it could cost so

build the perfect house it could cost so

build the perfect house it could cost so much

much

much so we put boundaries and this is what

so we put boundaries and this is what

so we put boundaries and this is what our society is accepting and there is a

our society is accepting and there is a

our society is accepting and there is a fundamental cornerstone of these codes

fundamental cornerstone of these codes

fundamental cornerstone of these codes which is what we call life safety and

which is what we call life safety and

which is what we call life safety and this is something that we have been

this is something that we have been

this is something that we have been using for many many many years more than

using for many many many years more than

using for many many many years more than 20 years

20 years

20 years what graph shows you and I refer you to

what graph shows you and I refer you to

what graph shows you and I refer you to the very end of it is that for the very

the very end of it is that for the very

the very end of it is that for the very rare event you will be on a state of

rare event you will be on a state of

rare event you will be on a state of collapse prevention that means that your

collapse prevention that means that your

collapse prevention that means that your structure is going to have a lot of

structure is going to have a lot of

structure is going to have a lot of damage it may not be working it may need

damage it may not be working it may need

damage it may not be working it may need to be destroyed but right after the

to be destroyed but right after the

to be destroyed but right after the earthquake it’s going to give you the

earthquake it’s going to give you the

earthquake it’s going to give you the chance to get out of it alive and that’s

chance to get out of it alive and that’s

chance to get out of it alive and that’s how we define life safety now this is

how we define life safety now this is

how we define life safety now this is something we have used for a very very

something we have used for a very very

something we have used for a very very long time

long time

long time and our society I think has moved beyond

and our society I think has moved beyond

and our society I think has moved beyond that because if you have this life

that because if you have this life

that because if you have this life safety objective you may not have

going to affect your happiness right and

going to affect your happiness right and all of these do not go into our mouth

all of these do not go into our mouth

all of these do not go into our mouth and in our code but there is a term that

and in our code but there is a term that

and in our code but there is a term that is used and oftenly overused called

is used and oftenly overused called

is used and oftenly overused called resilience that society demands and

resilience that society demands and

resilience that society demands and sometimes uses it without real and I was

sometimes uses it without real and I was

sometimes uses it without real and I was surprised when I went to Ecuador the day

surprised when I went to Ecuador the day

surprised when I went to Ecuador the day after in the front page of the biggest

after in the front page of the biggest magazine for the area of Manabi that

magazine for the area of Manabi that

magazine for the area of Manabi that basically it was a province that was

basically it was a province that was

Ecuador asking for resiliency they did

Ecuador asking for resiliency they did not ask rebuild my house give me back my

not ask rebuild my house give me back my

not ask rebuild my house give me back my job bring food for my children

they said resilience

they said resilience so is resiliency the answer to

so is resiliency the answer to

so is resiliency the answer to everything or resilience so looking at

everything or resilience so looking at

everything or resilience so looking at beauty pageants it has always been a

beauty pageants it has always been a

beauty pageants it has always been a very common question of what do you want

very common question of what do you want

very common question of what do you want to see for the world and historically I

to see for the world and historically I

to see for the world and historically I can show you over the time that always

can show you over the time that always

can show you over the time that always the answer has been world peace world

the answer has been world peace world

the answer has been world peace world peace until 2013 where a zillion thing

peace until 2013 where a zillion thing

peace until 2013 where a zillion thing was in fashion where Miss Philippines

was in fashion where Miss Philippines

was in fashion where Miss Philippines declared she wanted to sing resilience

declared she wanted to sing resilience

declared she wanted to sing resilience and she was crowned Miss World

and she was crowned Miss World

and she was crowned Miss World so sometimes we may overuse or think

so sometimes we may overuse or think

so sometimes we may overuse or think that resilience is the answer to

that resilience is the answer to

that resilience is the answer to everything but is it in engineering what

everything but is it in engineering what

everything but is it in engineering what we know for sure and is that we have to

we know for sure and is that we have to

we know for sure and is that we have to define things otherwise we cannot apply

define things otherwise we cannot apply

define things otherwise we cannot apply them we have tools and we need to use

those two we have come up with as a

those two we have come up with as a definition of the thousand among the

definition of the thousand among the

definition of the thousand among the thousands definitions of resilience is

thousands definitions of resilience is

thousands definitions of resilience is our ability to anticipate prepare for

and rapidly recover from disastrous events so essentially when you look at

events so essentially when you look at

events so essentially when you look at it even in the Greek dictionaries the

it even in the Greek dictionaries the

it even in the Greek dictionaries the resilience has a sense of elastic otakus

resilience has a sense of elastic otakus

resilience has a sense of elastic otakus or bouncing back and really I’m not sure

or bouncing back and really I’m not sure

or bouncing back and really I’m not sure if that’s the was engineers I don’t want

if that’s the was engineers I don’t want

if that’s the was engineers I don’t want to go back to this picture in hurricane

to go back to this picture in hurricane

to go back to this picture in hurricane sandy I don’t want to go back to this

sandy I don’t want to go back to this

sandy I don’t want to go back to this picture in Ecuador I want to bounce

picture in Ecuador I want to bounce

picture in Ecuador I want to bounce forward to something better and how do

forward to something better and how do

forward to something better and how do we do this one of the ways to to apply

we do this one of the ways to to apply

we do this one of the ways to to apply resilience is to plan ahead we cannot

resilience is to plan ahead we cannot

resilience is to plan ahead we cannot predict extreme events but we have tools

predict extreme events but we have tools

predict extreme events but we have tools to prevent them from becoming disasters

to prevent them from becoming disasters

to prevent them from becoming disasters and this has been proven FEMA the

and this has been proven FEMA the

and this has been proven FEMA the Federal Emergency Management Agency has

Federal Emergency Management Agency has

Federal Emergency Management Agency has in

in

in and has studied how much is a return in

and has studied how much is a return in

and has studied how much is a return in terms of prevention and you can see that

terms of prevention and you can see that

terms of prevention and you can see that if you invest $1.00 in prevention for

if you invest $1.00 in prevention for

if you invest $1.00 in prevention for wind or flood when that flood happens

wind or flood when that flood happens

wind or flood when that flood happens you will get back five dollars in return

you will get back five dollars in return

you will get back five dollars in return so prevention is really worth it it’s a

so prevention is really worth it it’s a

so prevention is really worth it it’s a little less for earthquakes but still

little less for earthquakes but still

little less for earthquakes but still you get a return so we know that

you get a return so we know that

you get a return so we know that resilience works we know we have seen it

resilience works we know we have seen it

resilience works we know we have seen it in the most important factor which is
