It is difficult to know how many fatalities and injuries in an earthquake may have been avoided by a mitigating action because the result without the mitigation can usually not be estimated with a useful reliability. The case of the evacuation before the 1975, M  7.3, Haicheng earthquake offers a rare opportunity to quantitatively estimate the number of casualties saved. We show that the computer tool QLARM has calculated the human losses in eight damaging earthquakes in China approximately… Expand
Human Losses and Damage Expected in Future Earthquakes on Faial Island–Azores
Since the 15th century, the death toll due to large earthquakes has reached approximately 6300 in the Azores and 17 for Faial Island. The likely number of fatalities and injuries in future largeExpand
Near-Real-Time Loss Estimates for Future Italian Earthquakes Based on the M6.9 Irpinia Example
The number of fatalities and injured was calculated, using the computer code QLARM and its data set and assuming information about the Irpinia 1980 earthquake became available in near-real-time. TheExpand
Duties of Earthquake Forecast: Cases and Lessons in China
Abstract The duties of earthquake forecasting are accomplished by a system with the output of the earthquake forecast serving the disaster risk management of the society. The system, with differentExpand

This chapter deals with some of the issues behind the vulnerability of that part of the Mexican population who are most exposed to natural hazards due to the site and conditions of their dwellings.Expand
Studies on earthquake precursors in China: A review for recent 50 years
Abstract Since the 1960s, China has been conducting a persistent and systematic observation and monitoring experiment to falsify the hypothesis of premonitory anomalies and the predictability ofExpand
Radon earthquake precursor: A short review
More than 100 publications reporting radon anomalies to precede earthquakes were evaluated. A clear apparent negative correlation between the number of reported anomalies and the published length ofExpand
Ethical Issues in the Decision-making for Earthquake Preparedness, Prediction, and Early Warning
Game theory is applied as a conceptual framework for the discussion of ethical issues in the decision-making for earthquake preparedness, prediction, and early warning. Evolutionary game theoryExpand

Predicting the 1975 Haicheng Earthquake
The publicized four-stage (long-term, middle-term, short-term, and imminent) prediction of the M 7.3 1975 Haicheng, China, earthquake once generated worldwide fascination. Yet the prediction processExpand
Constructing City Models to Estimate Losses Due to Earthquakes Worldwide: Application to Bucharest, Romania
We propose a method to calculate damage and human losses for cities in the developing world by averaging over an entire city, or its administrative districts. Bucharest, Romania, serves as anExpand
Delay times of worldwide global earthquake alerts
Quantitative estimates of earthquake losses are needed as soon as possible after an event. A majority of earthquake-prone countries lack the necessary dense seismograph networks, modernExpand
