The discoverer, Leonid Elenin, originally estimated that the comet nucleus was 3–4 km in diameter, [7] but more recent estimates place the pre-breakup size of the comet at 2 km. [8] Comet Elenin started disintegrating in August 2011, [9] and as of mid-October 2011 was not visible even using large ground-based telescopes.
The list incorporates high-quality earthquake source (i.e., origin time, location and earthquake magnitude) and fatality information from several sources. Earthquake locations are taken from the Centennial Catalog [ 1 ] and the updated Engdahl, van der Hilst and Buland earthquake catalog, [ 2 ] which is complete to December 2005.
479P/Elenin, with provisional designation P/ 2011 NO 1 (Elenin), is a periodic comet with an orbital period estimated at 13.3 years. [ 4 ] The comet was discovered on 7 July 2011 [ 2 ] when the comet was 2.38 AU from the Sun and 1.4 AU from the Earth and had an apparent magnitude of 19.5.

There were fears amongst the public that Comet Elenin travelling almost directly between Earth and the Sun would cause disturbances to the Earth's crust, causing massive earthquakes and tidal waves. Others predicted that Elenin would collide with Earth on 16 October. Scientists tried to calm fears by stating that none of these events were possible.
The U.S. Geological Survey said the earthquake measured magnitude 7.1 and was relatively shallow at a depth of about 6 miles. China's Earthquake Networks Center recorded the magnitude as 6.8 ...
