Context and question: According to a study by the China Earthquake Administration (CEA), the earthquake occurred along the Longmenshan fault, a thrust structure along the border of the Indo-Australian Plate and Eurasian Plate. Seismic activities concentrated on its mid-fracture (known as Yingxiu-Beichuan fracture). The rupture lasted close to 120 sec, with the majority of energy released in the first 80 sec. Starting from Wenchuan, the rupture propagated at an average speed of 3.1 kilometers per second 49° toward north east, rupturing a total of about 300 km. Maximum displacement amounted to 9 meters. The focus was deeper than 10 km.
When wasmost of the energy released during the initial eruption?
Answer: first 80 sec.

Context and question: The earliest record of the location appears as São João on a Portuguese map by Pedro Reinel in 1519. When John Rut visited St. John's in 1527 he found Norman, Breton and Portuguese ships in the harbour. On 3 August 1527, Rut wrote a letter to King Henry on the findings of his voyage to North America; this was the first known letter sent from North America. St. Jehan is shown on Nicholas Desliens' world map of 1541 and San Joham is found in João Freire's Atlas of 1546. It was during this time that Water Street was first developed, making it the oldest street in North America.[dubious – discuss]
What year did John Rut visit St. John's?
