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.
