Fractals in Geology and Geophysics

Donald L. Turcotte • Birkhäuser Basel eBooks (1989)

The definition of a fractal distribution is that the number of objects N with a characteristic size greater than r scales with the relation N ~ r −D . The frequency-size distributions for islands, earthquakes, fragments, ore deposits, and o...

Anomalous effect in Schumann resonance phenomena observed in Japan, possibly associated with the Chi-chi earthquake in Taiwan

M. Hayakawa, K. Ohta, A. P. Nickolaenko, A. P. Nickolaenko et al. • Annales Geophysicae (2005)

The Schumann resonance phenomenon has been monitored at Nakatsugawa (near Nagoya) in Japan since the beginning of 1999, and due to the occurance of a severe earthquake (so-called Chi-chi earthquake) on 21 September 1999 in Taiwan we have...
