5. Lots of progress – a few highlights
• Progress in building new schools to code
• Major programs for existing schools:
Cyprus, Turkey, Italy, Israel, Nepal and more
• Lots of awareness and preparedness programs
• Policy development and planning
But:
• The risk is still unacceptably high
• Countries continue to build unsafe schools
• Current efforts fall far short of what is needed
6. What Works
An effective school safety program will
1. Stipulate the desired safety performance for school
buildings and construct all new schools to meet this
standard;
2. Educate students on natural hazards and risk
reduction measures;
3. Provide preparedness training;
4. Review conditions of all existing school buildings
and retrofit, relocate or replace unacceptably
vulnerable buildings;
5. Draft and enact plans for post-event continuity of
education services.

Reducing Risk and Improving Preparedness, GeoHazards International
7. An example of doing what works:
New Zealand
• New schools built to code with earthquake
resistant provisions, beginning in 1935; new
unreinforced brick schools banned
• Unreinforced brick schools replaced 1935-1990s
• Vulnerability assessment of remaining 21,000
buildings, 1998-2001
• Work to remedy vulnerabilities 2002 onwards
• The Test: 2010-2011 Canterbury earthquakes
8. Major, costly damage (29 schools required rebuilding consent)
Education disrupted
NO Collapses
NO studentscourtesy Nicholas died at school New Zealand Ministry of Education

9. An example of quick action: Bhutan
• New schools built to a code beginning in 1998
without a major damaging earthquake
• Need for low-cost schools in remote areas
means some schools built with local materials
are not fully to code
• The Test: M6.1 2009 Mongar and 2011 Sikkim

11. Bhutan’s Response Since 2009
• Review + update of standard school designs
• Preparedness measures at school level
• Education and training
• National action plan to improve school
earthquake safety just completed
• Nationwide vulnerability assessment of
school buildings to start this year
12. Safe by 2033?

We need a focused, intensive global investment in
school earthquake safety
13. Get involved locally and globally!

Notas do Editor
2008 Wenchuan earthquakeXingful Primary School, Dujianyan, ChinaMore than 300 students died in this school collapse.2001 Gujarat earthquake,ShriSwaminarayan School, Ahmedabad, India32 students died in the staircase while descending from the terrace (flag hoisting ceremony for Republic Day). Building was only 11 months old. Parents sued and won Rs. 5 lakh compensation from the builders/trustees of the school. This building was approximately 300 km from the earthquake epicenter.
While this slide is interesting (and a couple of years old) it does not include one major ingredient needed to determine risk: the earthquake vulnerability of school buildings
This is an unreinforced brick school building in Delhi, India. The ceiling consists of heavy stone slabs – think acoustical tile ceilings but with stone slabs - resting on steel beams that in turn just sit on the walls. Nothing is tied together, and these buildings will come apart during strong shaking, just like schools in China did during the 2008 Wenchuan earthquake. These are very hazardous buildings, and the are still being built because they are fast to construct and schools are able to circumvent a burdensome approval process.
Am leaving out North America because other speakers will cover it
Direct hit while schools in sessionGround motions well above design levelsMost damage due to liquefaction and subsidence, cracks and fissures, rock falls, flooding
Community built schools hard hit; students not in school when the earthquake struck.
Note mismatches – plan irregularities, torsion. Either a data issue or an indication that these aren’t as severe as we think.
