Wel veel minder zwaar dan Japan en Ecuador.

Geen zorgen, dan mag hij nog wel een magnitude of 2,5 hoger zijn en moet het epicentrum in de stad liggen.quote:Op maandag 18 april 2016 09:58 schreef Perrin het volgende:

Dat was die van 5.9 net, nog wat sterker dus. Daarna nog één van boven de 4. Is het normaal dat er in krap een uur tijd nog drie van zulke schokken zijn, dagen na de "hoofdbeving"? In de vorige dagen zat er volgens mij steeds wel meerdere uren tussen.quote:
Dat kan wel normaal zijn ja... bij de ene zit er dagen tussen, soms uren...quote:Op woensdag 20 april 2016 11:37 schreef heywoodu het volgende:

Yup, wie weet een beving met kracht 12, en dan blijkt achteraf dat Pangea in 1 dag zover uit elkaar dreef dat in 1 dag de Atlantische oceaan ontstondquote:Op woensdag 20 april 2016 14:58 schreef Frutsel het volgende:
Ecuador earthquake: A megathrust is brewing in India, say experts
A subduction process similar to the one that caused the Ecuadorean quake is happening under the Himalayan region as well, where the Indian plate is getting inside the Chinese landmass.
This northward push has been creating a huge amount of tectonic strain in the region, making it particularly prone to earthquakes.
Also read: Nepal earthquake was big but The Big One is yet to come say experts.
Scientists believe there is so much energy stored in the area that an earthquake of magnitude greater than 8, possibly even 9, would be needed to release it. This earthquake can come at any time.
The Nepal earthquake was a result of this same process, but it was relatively weak in magnitude
Interestingly, historical data from the US Geological Survey shows that on an average only one earthquake of magnitude 8 or above, called as ‘great earthquakes’, takes place in a year anywhere in the world. This year there hasn’t been a 8-plus quake so far.
There have been aberrations. The year 2007, for example, witnessed as many as four 8-plus earthquakes – in Kuril Islands in north Pacific, Soloman Islands near Australia, central Peru, and in Sumatra in Indonesia. The years 1920, 1923, 1946, 1960 and 1995 each had three of these big events
On the other hand, in recent memory, 2002, 2008 and 2013, did not have any 8-plus earthquake. Still, the period after 2000 has been one of the most frequent for ‘great earthquakes’. As many as 20 of these events have happened in these 15 years. The frequency of earthquakes every year increases exponentially as we look at smaller magnitudes. Earthquakes of magnitude between 7 and 7.9 happen 15 times on an average every year, while 134 instances of earthquakes between 6 and 6.9 are recorded every year
