2005 Qeshm earthquake
The 2005 Qeshm earthquake occurred on November 27 at 13: 52 IRST. It was Iran’s second major earthquake of 2005, following that at Zarand in February. The epicenter was about 1,500 kilometers south of Tehran, close to Iran’s southern borders.
About 2005 Qeshm earthquake in brief
The 2005 Qeshm earthquake occurred on November 27 at 13: 52 IRST. It was Iran’s second major earthquake of 2005, following that at Zarand in February. The epicenter was about 1,500 kilometers south of Tehran, close to Iran’s southern borders. Iran experiences at least one minor earthquake per day on average, and the Zagros region is particularly prone to seismic activity. Since the start of the 20th century 1 in 3,000 Iranians have died in earthquake-related incidents. The United Nations’ Common Country Assessment for Iran states that the greatest damage occurs in rural areas, for which no building code exists. The 1990 Manjil–Rudbar earthquake, with at least 42,000 fatalities, cost Iran roughly 7. 2% of its Gross National Product for that year, and wiped out two years of economic growth. The majority of Iranian quakes occur in the upper crust, closeto the surface, which means that they are potentially more destructive. In terms of earthquake protection, Iran was named the “worst offender” in 2004 by Professor Roger Bilham of the University of Colorado at Boulder. It is not rigorously followed, despite the susceptibility of three quarters of Iranian major cities to damaging earthquakes.
The risk posed by poor engineering is of significant concern to the populace and an impediment to economic development. There is evidence of intermediate level detachment at some of the weaker layers, which mean that folds at different stratigraphic levels may have different depths, orientations, or wavelengths. The island is elongated W–SW–ENE, with a variety of large anticlinal folds that show a series of trends in the central part of the central axis of the island that pierces through the western end at its western end. The east end of the east coast is affected by a series of large anticlines that show that a variety of older sedimentary rocks are outcrop over the whole island, apart from a diapir of older Hormuz salt. The west end is affected by a range of older sediments that show the main trend of the main fold axes out to the coastline and the regional trend of Neogene sedimentary rock. The north coast is outcrop of Neogene sandstones and conglomerates.
