Una noticia sobre un terremoto de 4,4 grados en la escala Richter fue registrado por el Instituto Geográfico Nacional este domingo frente a las costas de Granada. Además de en Granada, una zona de alta actividad sísmica, también se sintió en otras cuatro provincias andaluzas, Almería, Jaén, Málaga y Córdoba.
This earthquake followed dozens of aftershocks of the 6.3 magnitude earthquake off Melilla early last week, which caused damage and injuries in the city of Melilla and concern in Malaga.
High seismic activity zones in Spain
These are not the only areas with high seismic activity in Spain. On the map we see in red the areas with the highest risk and in green and blue those with moderate risk (see initial image)
This news highlights the importance of elevator safety when we encounter this dangerous situation.
List of dangers in an elevator during an earthquake
The UNE-EN 81-77:2014 Part 77 standard contains a list of the most significant hazards that can be found in an elevator subject to seismic conditions. We discuss the 5 most important points:
Due to the way the machinery is distributed, the elements used for its operation and the emergency systems it includes, the hydraulic elevator avoids dangerous situations for users.
For all these reasons, it can be concluded that, in the event of an earthquake, the hydraulic elevator is much safer than the electric one.
