Monday, January 27: Seminar Given By Peter Brown, Western University

On Monday, January 27, 2014, a public talk was given by Peter Brown of Western University at the UCF Student Union. The title of Dr. Brown’s talk was The Impact Hazard From Small Asteroids: Lessons From The Chelyabinsk Airburst One Year Later. Below is the abstract and a link to view pictures of the event.


A year ago a small asteroid exploded without warning with the force of 500,000 tons of TNT over Chelyabinsk, Russia. Dr. Peter Brown is one of the leading experts on this event and will speak on the explosion and the hazards to Earth poised by small asteroids.  The impact hazard at the Earth due to small asteroids is uncertain. The root of this uncertainty is the poorly understood interaction of small asteroids in the atmosphere together with the associated impact effects at the ground together with the poorly constrained number of small objects impacting Earth. The Chelyabinsk airburst has provided detailed data on a well-observed damage-producing airburst for the first time. In this talk Dr. Brown will describe what we have learned about the Chelyabinsk airburst in the year since it occurred and what it may tell us more broadly about the effects we can expect from future impacts at the Earth.
