An online encyclopaedia of world housing has been developed to help improve the design of buildings in areas prone to earthquakes.
Unlike its offline counterpart, which costs around $900 (£760), the database is free for engineers and architects around the world to use.
The Earthquake Engineering Research Institute (EERI) encyclopaedia describes different types of housing in 30 countries, detailing the materials used and methods of construction.
The dwellings range from mud huts in Malawi to reinforced concrete tower blocks in Turkey.
EERI spokeswoman Marjorie Green explained that the online encyclopaedia would make a big difference because engineers and architects can learn from experiences in earthquake zones.
The service is available here.
