Actualización de las Condiciones de servicio
11 de octubre de 2013
Estamos actualizando las Condiciones de servicio de Google. Las nuevas Condiciones se publicarán el 11 de noviembre de 2013 y se podrán consultar en esta página.
Como sabemos que muchos de vosotros sois alérgicos a los textos legales, a continuación ofrecemos un resumen con un lenguaje sencillo.
Hemos realizado tres cambios:
- En primer lugar, hemos aclarado cómo pueden aparecer el nombre y la foto de tu perfil en los productos de Google (incluidos anuncios, reseñas y otros contextos comerciales).
- Puedes controlar si tu imagen y tu nombre aparecen en los anuncios a través de la configuración de recomendaciones compartidas.
- En segundo lugar, hemos incorporado un recordatorio para que utilices tus dispositivos móviles de forma segura.
- En tercer lugar, hemos añadido información sobre la importancia de que mantengas la confidencialidad de tu contraseña.
A continuación, se muestran algunos detalles más:
I mentioned three components to the new TOS, but there’s really only one thing that’s changing here; two out of three components are general safety and security reminders.
In the first place, Google will now display shared endorsements including your profile name and picture to people with whom you share content (connections in Google+ for instance).
This means if you rated, followed, or reviewed a business, your connections might see an ad for this establishment which includes your name, picture and what you thought of it.
Google stresses that “you’re in control of what you share” and explains how you can turn this offin ads if you’re uncomfortable with the notion (they do state this “doesn’t change whether your Profile name or photo may be used in other places such as Google Play.”) The TOS change does not apply to users who already turned this setting off; it will remain off.
Secondly, Google provides a tip to “use your mobile devices safely.” Essentially, this boils down to “Don’t go online while driving” and “obey the law.” Somehow I find this one akin to the disclaimer at the bottom of beer billboards that reads “Please drink responsibly.”
Lastly, Google offers some advice on password management, why you shouldn’t share your password, how they can alert you to unusual activity, and some steps on how to use 2-step authentication and application specific passwords.
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 theepicenter of the earthquake). The original formula is:
where A is the maximum excursion of the Wood-Anderson seismograph, the empirical function A0 depends only on the epicentral distance of the station, . In practice, readings from all observing stations are averaged after adjustment with station-specific corrections to obtain the ML value.
Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude; in terms of energy, each whole number increase corresponds to an increase of about 31.6 times the amount of energy released, and each increase of 0.2 corresponds to a doubling of the energy released.
Events with magnitudes greater than 4.5 are strong enough to be recorded by a seismograph anywhere in the world, so long as its sensors are not located in the earthquake’s shadow.
The following describes the typical effects of earthquakes of various magnitudes near the epicenter. The values are typical only and should be taken with extreme caution, since intensity and thus ground effects depend not only on the magnitude, but also on the distance to the epicenter, the depth of the earthquake’s focus beneath the epicenter, the location of the epicenter and geological conditions (certain terrains can amplify seismic signals).
|Magnitude||Description||Mercalli intensity||Average earthquake effects||Average frequency of occurrence (estimated)|
|Less than 2.0||Micro||I||Microearthquakes, not felt, or felt rarely by sensitive people. Recorded by seismographs.||Continual/several million per year|
|2.0–2.9||Minor||I to II||Felt slightly by some people. No damage to buildings.||Over one million per year|
|3.0–3.9||II to IV||Often felt by people, but very rarely causes damage. Shaking of indoor objects can be noticeable.||Over 100,000 per year|
|4.0–4.9||Light||IV to VI||Noticeable shaking of indoor objects and rattling noises. Felt by most people in the affected area. Slightly felt outside. Generally causes none to minimal damage. Moderate to significant damage very unlikely. Some objects may fall off shelves or be knocked over.||10,000 to 15,000 per year|
|5.0–5.9||Moderate||VI to VIII||Can cause damage of varying severity to poorly constructed buildings. At most, none to slight damage to all other buildings. Felt by everyone. Casualties range from none to a few.||1,000 to 1,500 per year|
|6.0–6.9||Strong||VII to X||Damage to a moderate number of well built structures in populated areas. Earthquake-resistant structures survive with slight to moderate damage. Poorly-designed structures receive moderate to severe damage. Felt in wider areas; up to hundreds of miles/kilometers from the epicenter. Strong to violent shaking in epicentral area. Death toll ranges from none to 25,000.||100 to 150 per year|
|7.0–7.9||Major||VIII or greater||Causes damage to most buildings, some to partially or completely collapse or receive severe damage. Well-designed structures are likely to receive damage. Felt across great distances with major damage mostly limited to 250 km from epicenter. Death toll ranges from none to 250,000.||10 to 20 per year|
|8.0–8.9||Great||Major damage to buildings, structures likely to be destroyed. Will cause moderate to heavy damage to sturdy or earthquake-resistant buildings. Damaging in large areas. Felt in extremely large regions. Death toll ranges from 1,000 to 1 million.||One per year|
|9.0 and greater||Near or at total destruction – severe damage or collapse to all buildings. Heavy damage and shaking extends to distant locations. Permanent changes in ground topography. Death toll usually over 50,000.||One per 10 to 50 years|
(Based on U.S. Geological Survey documents.)
The intensity and death toll depend on several factors (earthquake depth, epicenter location, population density, to name a few) and can vary widely.
Minor earthquakes occur every day and hour. On the other hand, great earthquakes occur once a year, on average. The largest recorded earthquake was the Great Chilean Earthquake of May 22, 1960, which had a magnitude of 9.5 on the moment magnitude scale. The larger the magnitude, the less frequent the earthquake happens.
