Aftershocks Following the 9 April 2013 Bushehr Earthquake, Iran

Modeling afterslip and aftershocks following the 1992 Landers earthquake

[1] One way to probe the rheology of the lithosphere and fault zones is to analyze the temporal evolution of deformation following a large earthquake. In such a case, the lithosphere responds to a known stress change that can be assessed from earthquake slip models constrained from seismology and geodesy. Here, we model the postseismic response of a fault zone that is assumed to obey a rate-str...

Aftershocks and Pore Fluid Diffusion Following the 1992 Landers Earthquake

Renormalization of earthquake aftershocks

Assume that each earthquake can produce a series of aftershock independently of its size according to its “local” Omori’s law with exponent 1+θ. Each aftershock can itself trigger other aftershocks and so on. The global observable Omori’s law is found to have two distinct power law regimes, the first one with exponent p− = 1− θ for time t < t ∗ ∼ κ−1/θ, where 0 < 1−κ < 1 measures the fraction o...

Infectious threats after Iran's Bushehr earthquake.

TO THE EDITOR—While the country had yet to fully recover from the devastating twin earthquakes in 2012 [1–4], Kaki (in Bushehr province, Iran) was jolted by a 6.1-magnitude earthquake on9April 2013, leaving 37 people dead and more than a thousand injured. Within few hours from the incident, immediate rescue measures were taken and the survivors were temporarily sheltered. Lying on the coastal r...

Iran’s Bushehr Earthquake at a Glance

On 9 April 2013, an earthquake of 6.1 magnitude hit southwestern Iran near the city of Khvormuj and the towns of Kaki and Shonbeh in Bushehr province. The official disaster mitigation committee took immediate actions to coordinate rescue teams equipped with 24-hour medical air assistance. Overall, 160 victims were transferred to and treated in the Khvormuj hospital, while 139 survivors were tra...
