  2. Richter scale - Wikipedia

    en.wikipedia.org/wiki/Richter_scale

    The Richter scale [1] (/ ˈ r ɪ k t ər /), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, [2] is a measure of the strength of earthquakes, developed by Charles Richter in collaboration with Beno Gutenberg, and presented in Richter's landmark 1935 paper, where he called it the "magnitude scale". [3]

  3. Seismic magnitude scales - Wikipedia

    en.wikipedia.org/wiki/Seismic_magnitude_scales

    K values are logarithmic, similar to Richter-style magnitudes, but have a different scaling and zero point. K values in the range of 12 to 15 correspond approximately to M 4.5 to 6. [59] M(K), M (K), or possibly M K indicates a magnitude M calculated from an energy class K. [60]

  5. Sea state - Wikipedia

    en.wikipedia.org/wiki/Sea_state

    Sea State 5 and 8 range. In oceanography, sea state is the general condition of the free surface on a large body of water—with respect to wind waves and swell —at a certain location and moment. A sea state is characterized by statistics, including the wave height, period, and spectrum. The sea state varies with time, as the wind and swell ...

    RCP 2.6 is a "very stringent" pathway. [4] According to the IPCC, RCP 2.6 requires that carbon dioxide (CO 2) emissions start declining by 2020 and go to zero by 2100.It also requires that methane emissions (CH 4) go to approximately half the CH 4 levels of 2020, and that sulphur dioxide (SO2) emissions decline to approximately 10% of those of 1980–1990.

  8. List of assigned /8 IPv4 address blocks - Wikipedia

    en.wikipedia.org/wiki/List_of_assigned_/8_IPv4...

    Each / 8 block contains 256 3 = 2 24 = 16,777,216 addresses, which covers the whole range of the last three delimited segments of an IP address. This means that 256 /8 address blocks fit into the entire IPv4 space. As IPv4 address exhaustion has advanced to its final stages, some organizations, such as Stanford University, formerly using 36.0.0 ...

  9. Time signature - Wikipedia

    en.wikipedia.org/wiki/Time_signature

    Most time signatures consist of two numerals, one stacked above the other: The lower numeral indicates the note value that the signature is counting. This number is always a power of 2 (unless the time signature is irrational), usually 2, 4 or 8, but less often 16 is also used, usually in Baroque music. 2 corresponds to the half note (minim), 4 to the quarter note (crotchet), 8 to the eighth ...
