A
moderate earthquake struck the
Gharwal Himalayas on
27 May 2003 at
09:53 AM local time. It had a
magnitude of Mb=5.0 and was felt widely
in the region.
The earthquake
was centred 12.1 kilometres W of
Bangina (Uttarakhand), India,
17.1 kilometres N of Chamoli (Uttarakhand), India,
21.3 kilometres W of Joshimath (Uttarakhand), India,
24.7 kilometres SW of Badrinath (Uttarakhand), India,
45.5 kilometres NE of Rudraprayag (Uttarakhand), India,
69.7 kilometres NE of Pauri (Uttarakhand), India,
109 kilometres NW of Almora (Uttarakhand), India,
126 kilometres
E of Dehradun (Uttarakhand), India.
The earthquake
was felt strongly in parts of the state of Uttarakhand. Many
people fled into the open in panic. Three buildings in Joshimath
and two at Chamoli, including a hospital and a dharamshala were
damaged. Many buildings in the region developed cracks. There were
also unconfirmed reports of building collapses in the rural parts
of Chamoli district.
Strong tremors were also
felt in the neighbouring districts of Tehri and Uttarkashi where
there was panic among the residents. It was also felt in Hindav,
Mandar, Bhudake and Nailchami in the Bansali area. Light tremors
were experienced in the Srinagar area in Gharwal as well as in parts
of the neighbouring state of Himachal Pradesh.
The main shock followed a M3.5 event, which stuck the same
region 11 minutes earlier. A mild aftershock of M2.9 was also felt
in the same region at 10:42 UTC (16:12 local time). This is the
strongest earthquake to hit this immediate region since March 1999,
when a Mw=6.6 earthquake killed nearly 100 people in Chamoli
district. |
