The Airbus A350 is a long-range, wide-body twin-engine airliner developed and produced by Airbus. The initial A350 design proposed by Airbus in 2004, in response to the Boeing 787 Dreamliner, would have been a development of the Airbus A330 with composite wings and new engines. Due to inadequate market support, Airbus switched in 2006 to a ...

This is a list of the oldest living people who have been verified to be alive as of the dates of the cited supporting sources. It was estimated in 2015 that between 150 and 600 living people had reached the age of 110. The true number is uncertain, as not all supercentenarians are known to researchers at a given time, and some claims cannot be validated or are fraudulent.
Earth Day is an annual event on April 22 to demonstrate support for environmental protection. First held on April 22, 1970, it now includes a wide range of events coordinated globally by EARTHDAY.ORG (formerly Earth Day Network)[1] including 1 billion people in more than 193 countries.[2][1][3] The official theme for 2024 is "Planet vs ...

Prior to the development of the magnitude scale, the only measure of an earthquake's strength or "size" was a subjective assessment of the intensity of shaking observed near the epicenter of the earthquake, categorized by various seismic intensity scales such as the Rossi-Forel scale. ("Size" is used in the sense of the quantity of energy released,...
The Richter scale was defined in 1935 for particular circumstances and instruments; the particular circumstances refer to it being defined for Southern California and "implicitly incorporates the attenuative properties of Southern California crust and mantle." The particular instrument used would become saturated by strong earthquakes and unable to...
The Richter magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs (adjustments are included to compensate for the variation in the distance between the various seismographs and the epicenterof the earthquake). The original formula is: 1. M L = log 10 A − log 10 A 0 ( δ ) = log 10 [ A / ...
These formulae for Richter magnitude ML are alternatives to using Richter correlation tables based on Richter standard seismic event (M L = 0 {\displaystyle M_{\mathrm {L} }=0} , A = 0.001 m m {\displaystyle A=0.001\mathrm {mm} } , D = 100 k m {\displaystyle D=100\mathrm {km} } ). Below, Δ {\displaystyle \textstyle \Delta } is the epicentral distan...
