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.
Initially, the USGS said the quake was a magnitude 8.2, prompting the tsunami warning for coastal Alaska and Canadaâs British Columbia, while the remainder of the US West Coast was under a watch. Mickey Varnadao, a specialist at the warning center in Palmer, Alaska, said an advisory remained in effect for parts of Alaska, from Kodiak Island to Prince William Sound.
