  2. International Fujita scale - Wikipedia

    en.wikipedia.org/wiki/International_Fujita_scale

    The International Fujita scale (abbreviated as IF-Scale) is a scale that rates the intensity of tornadoes and other wind events based on the severity of the damage they cause. [1] It is used by the European Severe Storms Laboratory (ESSL) and various other organizations including Deutscher Wetterdienst (DWD) and State Meteorological Agency ...

  3. Enhanced Fujita scale - Wikipedia

    en.wikipedia.org/wiki/Enhanced_Fujita_scale

    The Enhanced Fujita scale (abbreviated as EF-Scale) is a scale that rates tornado intensity based on the severity of the damage they cause. It is used in some countries, including the United States and France. [1] The EF scale is also unofficially used in other countries, including China and Brazil.

  4. VLT Survey Telescope - Wikipedia

    en.wikipedia.org/wiki/VLT_Survey_Telescope

    The VST dome among VLT's telescopes. It is located in the background between two of the VLT auxiliary telescopes (small round enclosures). The VST is an alt-azimuthal wide-field survey telescope with a primary mirror diameter of 2.65 meters that was constructed from 2007 to 2011 at the ESO Cerro Paranal Observatory, in Chile.

  5. Tornado intensity - Wikipedia

    en.wikipedia.org/wiki/Tornado_intensity

    The EF-scale is more specific in detailing the degrees of damage on different types of structures for a given wind speed. While the F-scale goes from F0 to F12 in theory, the EF-scale is capped at EF5, which is defined as "winds ≥200 miles per hour (320 km/h)". [9]

  6. Seismic intensity scales - Wikipedia

    en.wikipedia.org/wiki/Seismic_intensity_scales

    Seismic intensity scales categorize the intensity or severity of ground shaking (quaking) at a given location, such as resulting from an earthquake.They are distinguished from seismic magnitude scales, which measure the magnitude or overall strength of an earthquake, which may, or perhaps may not, cause perceptible shaking.

  7. Modified Mercalli intensity scale - Wikipedia

    en.wikipedia.org/wiki/Modified_Mercalli...

    The MM scale measures intensity of shaking, at any particular location, on the surface. It was developed from Giuseppe Mercalli's Mercalli intensity scale of 1902. While shaking experienced at the surface is caused by the seismic energy released by an earthquake, earthquakes differ in how much of their energy is radiated as seismic waves. They ...

  8. TORRO scale - Wikipedia

    en.wikipedia.org/wiki/TORRO_scale

    The TORRO tornado intensity scale (or T-Scale) is a scale measuring tornado intensity between T0 and T11. It was proposed by Terence Meaden of the Tornado and Storm Research Organisation (TORRO) , a meteorological organisation in the United Kingdom , as an extension of the Beaufort scale .

    The Very Large Array (VLA), an array of 27 dish antennas. The NRAO's facility in Socorro is the Pete Domenici Array Operations Center (AOC). Located on the New Mexico Tech university campus, the AOC serves as the headquarters for the Very Large Array (VLA), which was the setting for the 1997 movie Contact, and is also the control center for the Very Long Baseline Array (VLBA).
