If you felt this earthquake,
please take the time to fill out a felt report!
At least six people were injured
in the Jaisalmer area after being hit by
falling masonry or after jumping from buildings in panic.
This earthquake
was felt strongly for 15-30 seconds knocking out power at Jaisalmer,
displacing loose household items
and sending
people running outdoors; some jumped off the roofs of houses in
panic.
Students preparing to sit year-end examinations ran out of
examination centres. The walls or roofs of at least a dozen buildings
reportedly collapsed and at least 3,000 buildings developed cracks. Stones
were dislodged
from a wall inside the Sonar Killa near the Suraj Prol and fell near the entrance
of a school but no one was hurt. Stones were also dislodged near
the southern side of the fort. A decorative "chhatri" above the
Retiring Room on Platform 1 at the Railway station collapsed. The strongest
effects are reported to have been experienced in the Sheo Panchayant in Jaisalmer
district. Strong shocks were also perceived at Ramgarh in
Jaisalmer district and at Shiv tehsil in Barmer district. The
earthquake was felt at Barmer
where people went outdoors. Tremors were experienced at Bikaner, Fatehgarh,
Jaipur, Jalore, Jodhpur,
Khuiala, Mohangarh, Pokaran, Sankra, Sirohi, and Vinjorai. Outside Rajasthan, tremors were felt
in at Bhuj, Khavda and other parts of Kachchh in Gujarat and at
Hyderabad, Khairpur Mir, Sanghar, Sukkur and Umarkot in
Pakistan's Sindh province. Mild tremors were also felt in high-rise buildings
as far as Delhi, nearly 650 kilometres to the north-east.
This is the largest earthquake in this general area, as
well as in Rajasthan, since a Mw=5.4 earthquake near Jaisalmer on 8
November 1991 that caused some damage in the village of Konoi and
was felt as far as New Delhi. Southern and western parts of
Rajasthan were also affected by the
M7.7 2001 Bhuj earthquake that
caused some damage to buildings in the state, including the Sonar Killa in
Jaisalmer.
