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 had been a state for only 7 years when this huge earthquake triggered a tsunami of over 30 feet (10 meters). Despite its size, the quake caused little damage due to its remote location at the tip of the Aleutian Islands. The tsunami was reported in Hawaii and spread as far away as Japan.
