Global earthquake
deaths by earthquakes,
2000-2015
During 2000 to 2015
more than 575575
people were killed
Earthquake
Injuries
Earthquakes
estimated to
have an overall
average death
to injury ratio of
1:3–4

von Schreeb, 2018)
falling and moving
non-structural

among the major
causes of earthquake
deaths and injuries
Earthquakes & Indoor Objects
Earthquake may cause indoor objects
to:
1)
Fall
and overturn
2)
Move
and slide
3)
Break
and spread
4) Create
secondary hazards
The extent of fall, move, and spread
of objects during the earthquakes
depends on
1)
Earthquake
attributes,
2)
Building
attributes,
3)
Objects
characteristics
Human behavior
during the earthquakes
There is a close link between
the building contents and non
structural elements and human
behavior and actions during
the earthquakes.
Most Common
recommended protective
actions during earthquakes
•
‘Drop, Cover, and Hold
On’
•
This can be implemented
if:
•
Such covering objects exist
in the space
•
Access to them is not
restricted by the falling,
moving, and spreading
objects.
Earthquake Smart Space App
1. Detecting objects
2. Calculating risks
Earthquake Smart Space
Risk Assessment Method
Risk for each detected object
=
risk of falling
+
risk of moving
+
risk of spreading & breaking
Risk
= Probability (i.e. falling) * Impact (i.e. falling that depends on
size, weight, and location of the object)
