A bad day for Los Angeles?

Imagine if the comet 67P/Churyumov-Gerasimenko landed on Los Angeles.

The comet is approximately 2.7 miles by 2.5 miles at its longest and widest dimensions and speeds through space at 84,000 miles per hour.

Like other comets, 67P probably originated in the Kuiper belt and was ejected towards the interior of the solar system.

There is no risk of 67P crossing paths with Earth, but if it did, it would be a very bad day for Los Angeles and the rest of Southern California.
