Correspondence: Sina Zarrintan, MD Department of General Surgery Golgahst St. Imam Reza Hospital, Tabriz, 51664 Iran E-mails: [email protected], [email protected] The 2012 Iranian earthquakes took place in the cities of Ahar and Varzqan in East Azerbaijan province on August 11, 2012, at 4:53 PM Tehran time. Twin earthquakes (6.4 and 6.3 on the Richter scale) stuck northwest Iran 11 mi...

On October 9, 2014, a Mw 7.1–6.7 seismic doublet occurred at the Juan Fernández microplate, close to triple junction with Pacific and Nazca plates. The 7.1 earthquake is largest ever have been recorded in region. Its thrust focal mechanism also unusual for region, although northern part of microplate expected undergo compression. region remote seismological data limited station ~600 km distance...

In 2020, an earthquake doublet, a M7.8 on July 22nd and M7.6 October 19th, struck the Alaska-Aleutian subduction zone beneath Shumagin Islands. This is first documented doublet involving megathrust event strike-slip event. The partially ruptured seismic gap, which has not hosted large earthquakes since 1917, second was unusual as it broke trench-perpendicular fault within incoming oceanic slab....

A total of 907 cases of leprosy from two sources, records from Baba-Baghi Leprosarium (709 cases) and Ahar case finding survey (198 cases), have been studied. The main characteristics of the cases are: a) about 50% of all cases are lepromatous leprosy; b) the leprosarium cases are about 2.5 years younger; c) about 70% of all cases are male; and d) the incidence of leprosy shows a steady increas...

1. introduction the evidence of geology show that in all of times earth have been threatened by nature forces that may be earthquake is the strongest phenomenon among them. earthquake is one of the phenomenons of planet that have killed the thousands of people and have damaged to assets of people. earthquake by reason of expansion of territory and also expanse and intense of its damage is the m...

Abstract Mw 7.6 and 7.4 earthquakes occurred 16 h apart on April 12 13, 2014, at depths of 15 km 35 km, respectively, southwest Makira Island (San Cristobal) in the Solomon Islands. We study source mechanisms to investigate interrelation between two events, why Islands have a historically high rate doublet earthquakes. Teleseismic P waveform data for both events were used obtain slip distributi...

The addition of an extra stimulus pulse, or doublet, at the beginning of a low-frequency train has been shown to substantially increase isometric force. This study examined the effects of muscle movement on this doublet potentiation. The soleus muscles of anesthetized cats were stimulated at 10 Hz for 1 s, with and without an added doublet (0.01-s interval). Isovelocity releases reduced but did...
