The recent spate of earthquakes in Haiti, New Zealand, Chile and, the huge Mw
There are a couple of reasons why I think that things seem worse than before. The world is more populated than before. Therefore, when large earthquakes, an their accompanying tsunamis hit, there are more people to injure and kill, and more infrastructure to damage and destroy. In addition, information is so easily and rapidly transmitted these days, the devastation can be seen immediately, rather than taking days, as it would have in the 60s . The video below is an example of modern information technology, showing the havoc caused by the Japanese tsunami.
I also think that people forget quickly. When something new and "exciting" comes along we tend to forget things from the past. It seems to be human nature. It can be easily observed at the small scale in our own lives. Kids, and adults, get new toys and the old ones fall by the wayside. I know I've done it.
Most of what I have discussed comes from an article on The Panda's Thumb by Matt Young. Matt also discusses the problems around predicting earthquakes and how it basically cannot be done. Of course there are some that claim it can be. One such fellow is Ken Ring, or the "moon man". Ken Ring is known for his weather forecasting almanac based on lunar cycles. I don't know too much about it but apparently he can be broadly accurate. But I suspect that it comes less from the moon and more from studying trends. However, it seems Ken has decided that earthquakes can be predicted using the moon and tides. Ken recently appeared on the current affairs programme in NZ, Campbell Live. The average "interviewing" aside, John points out some obvious flaws in Ring's methods. For example, Ken Ring says that earthquakes are most likely to occur one week either side of new, or full moon. Now I would be the first to admit that my mathematics is poor but, seriously. One week either side of new or full moon makes four weeks. Four weeks makes a month. That is some ridiculously broad predicting. Not only that, but it is pseudosience that is misleading and actually quite dangerous. If you want to read more, Phil Plait has the details here.
