A strong
earthquake struck the
island of Little Andaman on 23 December 2006 at
01:20 AM local time.
The earthquake had a magnitude of Mw=6.3
and was felt in some parts of the southern Andaman Islands including
Port Blair. It did not result in any damage or casualties.
The earthquake was centred
2 kms N of Koname (Little Andaman Island),
India,
4.9
kms S of Jackson Creek (Little Andaman Island), India,
17.1 kms NW of Hut Bay (Little Andaman Island), India,
25.1 kms SW of Dugong Creek (Little Andaman Island), India,
84.7 kms SSW of Woodmason Bay (Rutland Island), India,
117 kms SSW of Port Blair (South Andaman Island), India.
174 kms NNW of Malacca IAF Base (Car Nicobar Island), India,
251 kms SSW of Mayabander (Middle Andaman Island), India,
442 kms NNW of Campbell Bay (Great Nicobar Island), India,
709 kms NW of Phuket International Airport (Phuket), Thailand.
This earthquake was strongly felt at Hut Bay and the rest of Little Andaman
Island causing considerable panic but no damage. Tremors were also
experienced as far north as Port Blair where people some ran
outdoors in fear. If you felt
this earthquake please take the time to fill out a
felt report questionnaire. This
earthquake was centred onshore near the
settlement of Koname to the south of Jackson Creek on the
west coast of Little Andaman Island. Although
the earthquake did not generate a tsunami there was some anxiety
among the residents of the islands, many choosing to move to
higher ground as a precaution. As word of the earthquake reached
mainland India via the electronic media, there was some panic
in Nagapattinam in Tamil Nadu where people fled to higher ground
as rumours spread of an impending tsunami.
This is the strongest earthquake in the Andaman
Islands since the Mw=6.0 Defence Island Earthquake on 3 February
2006 that was strongly felt in much of the three main islands in
the Andaman chain. It is also the strongest event in the entire
Andaman & Nicobar Archipelago since the start of 2006.
