1 00:00:00,000 --> 00:00:05,500 Hello! Dr. Textbook here with some earth-shattering facts! 2 00:00:08,500 --> 00:00:13,000 You'll never guess how many detectable earthquakes there are in the world each year. 3 00:00:13,500 --> 00:00:17,500 Try 500,000, that's half a million earthquakes a year! 4 00:00:17,500 --> 00:00:19,500 Californians, listen up! 5 00:00:19,500 --> 00:00:23,500 Every year the southern part of California has 10,000 earthquakes, 6 00:00:23,500 --> 00:00:25,500 but most of them are not felt! 7 00:00:25,500 --> 00:00:27,500 Yee-haw! 8 00:00:28,500 --> 00:00:31,500 Now, which state is the most earthquake-prone? 9 00:00:31,500 --> 00:00:33,500 Not California! Try... 10 00:00:33,500 --> 00:00:37,500 Alaska! It has a magnitude 7 earthquake every year! 11 00:00:37,500 --> 00:00:40,500 And here is a trick question! 12 00:00:40,500 --> 00:00:43,500 Is there such a thing as earthquake weather? 13 00:00:43,500 --> 00:00:50,500 No! Earthquakes happen in the cold, in the rain, and in the heat! 14 00:00:51,500 --> 00:00:55,500 Now, let's see if we can feel one of those 500,000 earthquakes! 15 00:00:57,500 --> 00:01:01,500 Not a very good idea!
