A major
earthquake (M7.0 to 7.9 termed as "major") occurred
beneath the Dalbandin area in western Balochistan, Pakistan,
on 19 January 2011
at 01:23 AM
local time in Pakistan. It had a magnitude of Mw=7.2. Due
to its depth, this earthquake has been extensively felt in south
Asia as well as in Afghanistan, Iran and in parts of the Arabian
peninsula.
The earthquake was centred
23.5 kms SE of Nulhi (Balochistan), Pakistan,
48.5 kms W of Dalbandin (Balochistan), Pakistan,
57.4 kms SE of Amuri (Balochistan), Pakistan,
145 kms WNW of Kharan (Balochistan), Pakistan,
216 kms WSW of Nuskhi (Balochistan), Pakistan,
315 kms SE of Zahedan (Sistan-va-Baluchistan), Iran,
353 kms SW of Kandahar (Kandahar), Afghanistan,
442 kms NNE of Gwadur (Balochistan), Pakistan,
537 kms NW of Karachi (Sindh), Pakistan,
795 kms NE of Muscat, Oman,
927 kms SE of Faisalabad (Punjab), Pakistan,
1419 kms NW of Mumbai (Maharashtra), India.
If you felt this earthquake, please take the time to fill out a felt report questionnaire.
Due to the depth of this
earthquake it has been widely felt by people in tall buildings in
many cities in Pakistan and India as well as in Afghanistan and Iran.
Tremors were also perceptible in tall buildings in several Gulf
states including in Bahrain, Oman, Saudi Arabia and in the UAE.
At least three deaths in
Pakistan were associated with this earthquake. Two women suffered
fatal heart attacks in Jacobabad and Quetta while another woman was killed
in a wall collapse at Gahri Khairo near Shahdadkot in upper Sindh.
At least three people were admitted to hospital in Multan after
suffering heart attacks. Several people were also injured in roof collapses at Dalbandin in
Balochistan. Two people were injured when a roof collapsed in Jhang
Maghiana in Punjab. One person was hospitalised after jumping from the
second floor of a building in the Timarpur area in Delhi, India.
As many as 200 mud
buildings were damaged in the Dalbandin, Kalat and Kharan districts
in Balochistan. Many buildings developed cracks across south-western Pakistan as far as
in Larkana, in Karachi and in Quetta. At least ten buildings were
badly damaged or collapsed at Kashmor in upper Sindh. The earthquake was strongly felt in Karachi
causing widespread panic and sent many people running outdoors. People
in the suburbs of Al Karam, Clifton, Defence, Gulistan-e Jauhar, Jauhar
More and Nazimabad gathered
in the open while some began reciting verses from the Koran. A four
storey building in the Karachi suburb of Liaquatabad leaned to one side and had to be evacuated. This is
the strongest earthquake in Karachi and southern Sindh since the
2001 Bhuj earthquake. In rural
parts of Balochistan, guns were fired in the air to awaken those
asleep. Strong tremors at Hyderabad (Sindh) rattling
windows and shaking furniture. Hundreds of people fled into the
street in panic. The earthquake was also felt strongly
at Dera Murad Jamali, Gwadur, Jaffarabad, Kharan, Naseerabad, Quetta,
Sohbatpur and Sibi in Balochistan, at
Bahawalpur, Dera Ghazi Khan, Islamabad, Lahore, Rahin Yar Khan,
Rawalpindi, Sargodha and
Vihari in Punjab as well
as at Badin, Guddu, Larkana, Khandkot, Karachi, Khairpur, Mirpur Khas, Nawabshah, Naushero
Feroz, Shikarpur, Sukkur, Thal and Thatta in Sindh.
There are reports of
buildings being damaged in Rajasthan in north-western India. At
Jaisalmer, loose stones were dislodged from the Jaisalmer Fort. Doors and
windows rattled in Jodhpur. Elsewhere in
Rajasthan the earthquake was felt at Ajmer, Alwar, Barmer, Bikaner,
Bhilwara, Jaipur, Kota, Pokaran, Puskhar, Sriganganagar, Suratgarh
and Udaipur. Minor cracks developed in the walls of a few houses in
the Khavda area of Kachchh district in Gujarat. In Delhi, mild to strong tremors were felt at many
locales and felt reports were received from Gautam Nagar, Hauz Khas,
Malviya Nagar, Mayur Vihar, Patel Nagar, Pitampura, Safdarjang and
Sarojini Nagar. Tremors were also felt at Faridabad, Gurgaon and
Hisar in Haryana, at Gwalior in Madhya Pradesh, at Chamba, Kangra
and Shimla in Himachal Pradesh, at Ghaziabad and NOIDA in Uttar Pradesh as well as
in parts of the states of Punjab and Uttarakhand. This earthquake
might also have been felt in Mumbai and as far south as Bengaluru
and Kochi.
This is the largest
earthquake in this general area since 18 April 1983 when a Mw=7.0
earthquake along the Iran-Pakistan border that shook south-eastern
Iran was felt as
far as Karachi. Intermediate depth earthquakes in this general area
are infrequent but not unusual. The normal faulting mechanism of this earthquake along with its depth suggests
that it might have occurred either within the subducting Arabian
Plate or within the over-riding Eurasian Plate but not along the
interface between the two plates.
