Aftershocks and fluctuating diffusivity
Sumiyoshi Abe, Norikazu Suzuki, Dmitrii A. Tayurskii
The Omori-Utsu law shows the temporal power-law-like decrease of the frequency of earthquake aftershocks and, interestingly, is found in a variety of complex systems/phenomena exhi…
Scaling and memory in seismological phenomena
Sumiyoshi Abe, Norikazu Suzuki
The concept of memory is of central importance for characterizing complex systems and phenomena. Presence of long-term memories indicates how their dynamics can be less sensitive t…
Brain activity vs. seismicity: Scaling and memory
Sumiyoshi Abe, Norikazu Suzuki
The brain activity and seismicity share a remarkable similarity. The Gutenberg-Richter law describing a power-law relation between the frequency of earthquake occurrence and releas…
Subdiffusion of volcanic earthquakes
Sumiyoshi Abe, Norikazu Suzuki
A comparative study is performed on volcanic seismicities at Icelandic volcano, Eyjafjallajökull, and Mt. Etna in Sicily from the viewpoint of complex systems science, and the disc…
Anomalous diffusion of volcanic earthquakes
Sumiyoshi Abe, Norikazu Suzuki
Volcanic seismicity at Mt. Etna is studied. It is found that the associated stochastic process exhibits a subdiffusive phenomenon. The jump probability distribution well obeys an e…
Universal clustering structure and C~0.85 scaling in complex earthquake networks
Sumiyoshi Abe, Norikazu Suzuki
Earthquake network captures the complexity of seismicity in a peculiar manner. Given a seismic data, the procedure of constructing an earthquake network proposed in [S. Abe, N, Suz…
