[edit] Second sentence unclear

The second sentence under the subhead on the article page needs to be reworked; it doesn't make sense as it stand. Looks like perhaps something was copied incorrectly or incompletely.

If this isn't the right place to put this comment, please let me know. I'm a noob.

[edit] Richter Scale

I was just looking through a book and found some rough Richter equivalents to these. If anyone thinks this might be appropriate, tell me and I will supply them (although I cannot edit tables myself, I don't have the knowledge.)Squid 17:56, 8 June 2007 (UTC)

You can find this in the Romanian article: ro:Scara Mercalli (and also the table syntax). Could you check if it corresponds with your sources? --Alex:Dan 11:15, 19 June 2007 (UTC)
They are grouped differently but roughly follow the same pattern. I'll get back to you soon... Squid 18:13, 10 October 2007 (UTC) —Preceding unsigned comment added by Squidnchips (talkcontribs)

i like thnigs


Intensity is a measure of earthquake effects; magnitude is a measure of the energy output. The two cannot be directly compared.

A car analogy: Intensity is like 0-60 time, while magnitude is engine displacement. A bigger engine usually means faster times, but this is affected by car weight, transmission, wheel traction, road quality, etc.

Similarly, a higher magnitude earthquake creates higher intensities, but it is affected by various factors-- your distance from the earthquake, soil condition, rupture directivity, type of buildings, etc. 68.32.210.166 02:44, 9 October 2007 (UTC)trickpony Do catastrophic earthquakes cause haboobs? After all, the greatest earthquakes cause massive mudslides and throw rocks, people, cars I assume, etc. into the air, do they also cause massive, towering clouds of sand in desert regions? 24.184.234.24 (talk) 02:46, 2 June 2009 (UTC)LeucineZipper —Preceding unsigned comment added by 24.184.234.24 (talk) 02:43, 2 June 2009 (UTC)

[edit] Source

The scale chart is from Cambridge Encyclopedia. I own a 2006 version of this encyclopedia.-- Vintei  Talk  18:19, 8 July 2008 (UTC)

[edit] This scale doesn't measure intensity

Actually it doesn't measure anything. It's not even a scale really. It's just a classification scheme where earthquakes are classified according to their perceived effects by people. Two equally intense earthquakes may be classified on different categories (so called "degrees" here) depending on whether there were people and/or human constructions on the areas the earthquakes took place. This is just a subjective classification scheme. —Preceding unsigned comment added by 200.86.177.42 (talk) 09:35, 11 December 2009 (UTC)

[edit] Calligraph scale?

I've marked this term (bottom of article) 'citation needed' because I couldn't Google any references to this phrase, or to its assertion. The 'Calligraph scale' also doesn't appear on the Seismic scale page. (And don't know a better template.) I'm guessing the editor meant the old-fashioned pen-ink Kinemetrics seismometer??

[edit] Level XIII - Cataclysmic

From a textbook I had at school a while back, the Mercalli scale had a level that was even higher than XII-Catastrophic. It was XIII-Cataclysmic, when the damage is so extensive that maps of the affected areas have to be redrawn from scratch. Has this been abandoned, or was there just no real consensus about this extra level? -- Blanchardb -MeMyEarsMyMouth- timed 02:41, 22 January 2010 (UTC)
