| Zusammenfassung |
The global CATDAT damaging earthquakes and secondary effects (tsunami, fire,
landslides, liquefaction and fault rupture) database was developed to
validate, remove discrepancies, and expand greatly upon existing global
databases; and to better understand the trends in vulnerability, exposure,
and possible future impacts of such historic earthquakes.
Lack of consistency and errors in other earthquake loss databases frequently
cited and used in analyses was a major shortcoming in the view of the
authors which needed to be improved upon.
Over 17 000 sources of information have been utilised, primarily in the last
few years, to present data from over 12 200 damaging earthquakes
historically,
with over 7000 earthquakes since 1900 examined and validated before
insertion into the database. Each validated earthquake includes
seismological information, building damage, ranges of social losses to
account for varying sources (deaths, injuries, homeless, and affected), and
economic losses (direct, indirect, aid, and insured).
Globally, a slightly increasing trend in economic damage due to earthquakes
is not consistent with the greatly increasing exposure. The 1923 Great Kanto
($214 billion USD damage; 2011 HNDECI-adjusted dollars) compared to the
2011 Tohoku (>$300 billion USD at time of writing), 2008 Sichuan and
1995 Kobe earthquakes show the increasing concern for economic loss in urban
areas as the trend should be expected to increase. Many economic and social
loss values not reported in existing databases have been collected.
Historical GDP (Gross Domestic Product), exchange rate, wage information,
population, HDI (Human Development Index), and insurance information have
been collected globally to form comparisons.
This catalogue is the largest known cross-checked global historic damaging
earthquake database and should have far-reaching consequences for earthquake
loss estimation, socio-economic analysis, and the global reinsurance field. |
