The emergency alert map website : http://hisz.rsoe.hu/alertmap/index2.php : has a long back-dated list of reports of mass animal deaths - maybe that will help you populate your map?
I think having separate maps for different 'events' is a good idea - as with so many different things happening I imagine they will get very crowded! It will be very interesting however, to have a few of them open at the same time to compare them with one another.
For events that 'could be' (for example) meteors, but aren't necessarily reported as one; perhaps you could use a different icon, but use your current 'date' colour code applied to that different icon? Similar to the idea about landslides or sinkholes.
So - labeling as 'suspected' meteor or sinkhole - or even 'alleged' if it may 'not' be but is reported as one... Not sure =) just a couple of things that I thought about.
