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. [7] [8] [9] The following describes the typical effects of earthquakes of various magnitudes near the epicenter. [10]
Logo of Eurocode 8. In the Eurocode series of European standards (EN) related to construction, Eurocode 8: Design of structures for earthquake resistance (abbreviated EN 1998 or, informally, EC 8) describes how to design structures in seismic zone, using the limit state design philosophy. It was approved by the European Committee for ...
First, the scale is logarithmic, so that each unit represents a ten-fold increase in the amplitude of the seismic waves. [12] As the energy of a wave is proportional to A 1.5, where A denotes the amplitude, each unit of magnitude represents a 10 1.5 ≈32-fold increase in the seismic energy (strength) of an earthquake.

The following Technical Committees exist or existed within CEN: [4] Basic standards. Drawing practice. Gaseous and liquid fuels, lubricants and related products of petroleum, synthetic and biological origin. Gas-fired sorption appliances, indirect fired sorption appliances, gas-fired endothermic engine heat pumps and domestic gas-fired washing ...
CENELEC (French: Comité Européen de Normalisation Électrotechnique; English: European Committee for Electrotechnical Standardization) is responsible for European standardization in the area of electrical engineering. Together with ETSI (telecommunications) and CEN (other technical areas), it forms the European system for technical ...

EN 19: Industrial valves – Marking of metallic valves. EN 20: Wood preservatives. EN 26: Gas-fired instantaneous water heaters for the production of domestic hot water.
Their orbit is moderately eccentric, as it has an eccentricity of almost 0.52; [5] their closest approach or periastron is 11.2 AU (1.68 × 10 ^ 9 km), or about the distance between the Sun and Saturn; and their furthest separation or apastron is 35.6 AU (5.33 × 10 ^ 9 km), about the distance between the Sun and Pluto.
