Balakot, Pakistan Earthquake of 8 OctoberMw7.
Physical Map of the Northern Pakistan and Kashmir Region affected by the Earthquake Landslides The high relief of unstable mountains makes Northern Pakistan very vulnerable to extensive landslides when an earthquake strikes the region.
Heavy monsoon rains - particularly if they occur before or after an earthquake, can be the catalyst to further devastating landslides. The earthquake of 8 October was responsible for many landslides.
Strong earthquake aftershocks may also trigger additional landslides of unstable mountain slopes and endanger villages in the region. As it can be seen from the two images below taken by the Advanced Spaceborne Thermal Emission and Reflection Radiometer ASTER before and after the earthquake, there were extensive landslides in and around the city of Muzaffarabad.
The landslides blocked the roads, thus further isolating the stricken region. In the ASTER images below, vegetation is shown in red, water is shown in blue and the city of Muzaffarabad is shown in grey.
The image taken on October 27, almost three weeks after the earthquake shows the land exposed by landslides to be white and tan in color. Tectonic Setting - Geological Instability - Regional Seismic Activity The earthquake occurred along a tectonic boundary which is characterized by high seismic activity.
Major tectonic elements along this particular zone of deformation were formed during the Cenozoic and Mesozoic eras. The zone extends from the Makran region in southwest Pakistan, to the Hazara-Kashmir syntaxial bend in the north.
This seismic boundary has been formed by the interaction of the Indian, Arabian and Eurasian Plates. It collides and is forced beneath the Eurasian tectonic plate. This process has continued for millions of years. Compression along these boundaries results in thrust or reverse type of faulting with the net result being an upward displacement of crustal material.
In the northern part of Pakistan, the Hindu Kush mountains converge with the Karakoram Range, a part of the Himalayan mountain system. Epicenter of the 8 October earthquake Modified base map after Jadoon and Khurshid, Seismicity of the region USGS graphic.
Most of the earthquakes in Pakistan occur in the north and western regions, along the boundary of the Indian tectonic plate with the Iranian and Afghan micro-plates. As mentioned, the more intense seismic activity occurs near regions of thrust faulting which is developing at the Himalayan foothills in both Northern Pakistan and Northern India.
In the last hundred years eight earthquakes with magnitude of more than 6 have been recorded in the Uttar Pradesh region of India. These quakes resulted by the gradual shifting of the India tectonic plate beneath the Tibetan plate in the geologically young Himalayan Mountain range and along the Himalayan arc.
The great Quetta earthquake M7. The powerful earthquake devastated the town of Quetta and the adjoining region. The October 8, earthquake occurred near this active seismic zone in Northern Pakistan, in the Himalayan foothills.
Its focal mechanism and slip and strike components are consistent with the compressive type of thrust faulting which is characteristic for the region and has resulted in folding and the formation of extensive anticlinal ridges in the vicinity of Muzaffarabad - Pakistani Kashmir's main city. Also, other major thrust zones exist along the Kirthar, Sulaiman and Salt mountain ranges of Pakistan.
As indicated, numerous earthquakes occur along the Chaman Fault System. Four major faults exist in and around Karachi and other parts of deltaic Indus, and the southern coast of Makran. The first of these is the Allah Bund Fault.
Earthquakes along this particular fault have been responsible for considerable destruction in the past.
A major earthquake in the 13th century destroyed Bhanbhor. Another major earthquake inwas responsible for extensive damage in Shahbundar. The second major fault near Karachi is an extension of the one that begins near Rann of the Kutch region.
The third is the Pubb fault which ends into Arabian sea near the Makran coast. Finally, the fourth major fault near Karachi is located in the lower Dadu district, near Surajani.
Many earthquakes have occurred on these faults.But for some, the greatest change brought about after October 8, , was at the Line of Control.
On October 29, the same year, both countries inked an agreement to open the LoC at five points. 8 اکتوبر کو آزاد کشمیر سمیت ملک کے شمالی علاقےمیں آنے والے قیامت خیز زلزلے کو دس سال مکمل ہو گئے.
The Kashmir earthquake occurred at Pakistan Standard Time on 8 October in Pakistan administered areas of Kashmir. It was centered near the city of Muzaffarabad, and also affected Pakistan's Khyber Pakhtunkhwa province and the Indian state of Jammu and Kashmir.
