GnRH stimulates the pituitary gland to produce follicle stimulating hormone (FSH), the hormone responsible for starting follicle (egg) development and causing the level of estrogen, the primary female hormone, to rise.
The Great Alaska Earthquake lasted for nearly five minutes and registered a magnitude of 9.2, still the largest ever recorded in North America and second only to the 9.5-magnitude quake that struck Chile in 1960.
Alaska is one of the world's most seismically active areas. 11% of the world's earthquakes occur in Alaska, and three of the 10 largest earthquakes ever recorded in world history were in Alaska. The only reason that the total death toll for the Good Friday Earthquake didn't even come close to the large December 26, 2004 Asia 9.0 earthquake is because Alaska is so sparsely populated. Alaska's population has grown greatly since 1964, so if the same quake was to happen again, the death toll would easily be much higher.
