Earthquake fatality measure offers new way to estimate impact on countries

Earthquakes are one of the most devastating natural disasters, causing loss of life and extensive damage to property. Scientists have developed a new measure called the Earthquake Fatality Load (EQFL) to provide a more accurate estimation of the impact of earthquakes on different countries. This measure takes into account the number of earthquake-related fatalities in a country relative to its population size, offering a unique perspective on the true impact of earthquakes.

Impact of Earthquakes: Past and Present

According to the research findings, countries such as Ecuador, Lebanon, Haiti, Turkmenistan, Iran, and Portugal have been among the most severely affected by earthquake fatalities in the past 500 years. Surprisingly, the study reveals that smaller countries tend to suffer more from earthquake fatalities, even if they experience fewer fatal earthquakes. This is because the loss of life represents a larger proportion of their population compared to larger countries.

Evolution of Resilience and Mitigation Strategies

The researchers pointed out that global trends, such as urbanization and advancements in building technology, have contributed to the reduction in EQFL over time. The migration of people from rural areas to cities has led to the construction of buildings that are more resistant to earthquake shaking, thereby reducing the risk of fatalities. Additionally, countries have become more efficient in providing aid and rescue operations during earthquakes, further mitigating the impact on human life.

Advocating for Earthquake Fatality Prevention

Max Wyss, a prominent advocate for emphasizing earthquake fatalities as a key measure of earthquake impact, has been instrumental in developing tools like QLARM (Quake Loss Assessment for Response and Mitigation) to assess and mitigate earthquake-related risks. The focus on preventing human loss rather than property damage is crucial in earthquake preparedness and response efforts. Wyss and his team have been working tirelessly to provide real-time calculations of fatalities, injuries, and building damage to facilitate prompt response and rescue operations during earthquakes.

Wrapping up, the Earthquake Fatality Load (EQFL) offers a valuable insight into the varying impact of earthquakes on different countries, emphasizing the need for proactive measures to minimize human casualties. By understanding the unique vulnerabilities of each region and implementing effective mitigation strategies, societies can better prepare for and respond to seismic events, ultimately saving lives and reducing the human toll of earthquakes..


What is the Earthquake Fatality Load (EQFL)?

The EQFL is a measure that compares the number of earthquake fatalities to the population size of a country in the year of the earthquake, providing an accurate estimation of the impact of earthquakes on different countries.

How is the EQFL calculated?

The EQFL is calculated by dividing the number of earthquake fatalities by the population estimate of the country in the year of the earthquake.

Which countries have been most severely affected by earthquake fatalities?

According to the research, countries such as Ecuador, Lebanon, Haiti, Turkmenistan, Iran, and Portugal have experienced the highest EQFL rankings in the past 500 years.

What factors contribute to a high EQFL ranking?

Smaller countries and those without major tectonic plate boundaries and slow deformation accumulation rates on faults tend to have higher EQFL rankings.

How has the EQFL changed over time?

The EQFL has decreased over time due to advancements in building technology, improved building resilience, and faster emergency response mechanisms.

Lists of earthquakes
Earthquakes are caused by movements within the Earth's crust and uppermost mantle. They range from events too weak to be detectable except by sensitive instrumentation, to sudden and violent events lasting many minutes which have caused some of the greatest disasters in human history.
