Reduced seismic activity after mega earthquakes
Yongwen Zhang, Maor Elbaz, Shlomo Havlin +1
Mainshocks are often followed by increased earthquake activity (aftershocks). According to the Omori-Utsu law, the rate of aftershocks decays as a power law over time. While afters…
Asymmetry in earthquake interevent time intervals
Yongwen Zhang, Yosef Ashkenazy, Shlomo Havlin
Here we focus on a basic statistical measure of earthquake catalogs that has not been studied before, the asymmetry of interevent time series (e.g., reflecting the tendency to have…
Improved Earthquake Forecasting Model Based on Long-term Memory in Earthquake
Yongwen Zhang, Dong Zhou, Jingfang Fan +3
A prominent feature of earthquakes is their empirical laws including memory (clustering) in time and space. Several earthquake forecasting models, like the EpidemicType Aftershock…
Scaling Laws in Earthquake Memory for Interevent Times and Distances
Yongwen Zhang, Jingfang Fan, Warner Marzocchi +4
Over the past decades much effort has been devoted towards understanding and forecasting natural hazards. However, earthquake forecasting skill is still very limited and remains a…
