There are so many places to look for earthquake and Tsunami related information, especially since the large Tsunami hit Sri Lanka. But, to make it more place based. I would put this website https://www.aeic.alaska.edu/seis/recenteqs/index.html. This tells all the recent earthquakes in alaska. I love this site, there is always a recent earthquake in alaska, and often times there is one close to Fairbanks. Then I would talk about the 1964 earthquake https://www.aeic.alaska.edu/quakes/Alaska_1964_earthquake.html and show pictures. I would also show pictures of the damage caused by the Tsunami in Alaska and Sri Lanka.
