Lithospheric strength and intraplate seismicity in the New Madrid seismic zone

Evaluation of the Recent Intraplate Seismic Activity on Cochinos Bay, Cuba

“…The deformation of continental interiors can be represented by relatively simple rheological models. Using these mentioned authors and the results of (Johnston and Kanter, 1990;Liu and Zoback, 1977;Sbar and Sykes, 1973;Stein, 1999) we can say that: 1) the tectonic forces of the plate margins can be Mario Octavio Cotilla Rodríguez. Evaluación de la actividad sísmica de interior de placa reciente en la Bahía de Cochinos, Cuba transmitted inside the plates for up to distances of 2,000 km; 2) the status of the forces in the interior continental zone seems to be relatively independent of the immediate surroundings, as well as of the previous tectonic style; 3) there is a predominance of transmission of energy from the borders toward the interior of the plate; 4) intraplate seismic events occur in areas where the crust has been weakened by previous activity.…”

“…The results of (Assinovskaya and Soloviev, 1994;Backmanov and Rasskazov, 2000;Guelfand et al, 1976;Gvshiani et al, 1987;Mackey et al, 1977;Sherman and San`kov, 2010;Stein and Yeats, 1989;Zhidkov, 1985;Zhidkov et al, 1975) contributed to develop the methodology of the active structures. In order to obtain the comprehension of the earthquakes localization on intraplate zones were used (Campbell, 1978;Jonston, 1989;Johnston and Kanter, 1990;Leonov, 1995;LeRoy and Mauffret, 1996;Liu and Zoback, 1977;Sbar and Sykes, 1973;Stein, 1999;Sykes, 1978;Zoback, 1992). Our main published results about this field are in the table 4.…”

Predicting heat flow in the 2001 Bhuj earthquake (<i>M</i><sub>w</sub>=7.7) region of Kachchh (Western India), using an inverse recurrence method

“…An average crustal model constructed from such tomograms over an area of 23.3 • to 23.7 • N and 69.9 • to 70.2 • E is shown in Fig. 3, which indicates an extremely complex crust mantle structure (Mandal and Pandey, 2010) below the earthquake affected region, somewhat similar to New Madrid Seismic Zone (Liu and Zoback, 1997). Thermal parameters and crustal structure used in heat flow estimation are included in Tables 1 and 2.…”

“…On the basis of regional network data and seismic reflection surveys, Mooney et al (1983) proposed a five-layer crustal model for the region, which consists of a 14 km thick altered lower crust. Details of crustal layers, together with the relevant geothermal parameters (Mooney et al, 1983;Liu and Zoback, 1997;Bedle and Lee, 2006), are given in Table 1. In this zone, measured heat flow is about 60 mW m −2 and depth to the LAB is about 72 km, as obtained below the Reelfoot rift through tomographic study (Bedle and Lee, 2006).…”

“…Heat generation and thermal conductivity for sediments as well as of underplated magmatic crust are taken from Liu and Zoback (1997). Mid crustal heat generation is an important parameter in elucidation of thermal regime inside the earth, which cannot be measured directly.…”
