Building collapse due to the World’s dams in Bangalore 26 November 2013 at 845-945 AM IST:
“The collapsed house was part of a several dwellings in a two-storeyed structure situated atop a godown in the compound. The collapse of the dwellings atop the godown around 8.45 am also led to crumbling down of other houses adjoining the godown, officials said.
While two families occupied the dwellings atop the godown, about ten to twelve people resided in the other adjoining houses that crashed subsequently. Most of the families living in the residential complex were daily wagers, who had left for work in the morning. Or else, the number of casualties could have been higher, a police official added.
Police said that the houses in the compound were about 40 years old and incessant rains over the last two or three days could have caused the collapse.”
The earthquakes between which the building collapsed:
2013-11-26 03:05:38.0 52.91 N 160.39 E 48 4.5 OFF EAST COAST OF KAMCHATKA
2013-11-26 04:28:40.61 28.51 N 56.75 E 22 3.5 SOUTHERN IRAN
The distance between the two epicenters: 8354 km.
Location of Bangalore: 12.9716,77.5946
The distance between the Southern Iran quake and Bangalore: 2791 km.
The distance between the Kamchatka quake and Bangalore is 8354-2791= 5563 km.
The time between the two quakes= 1:23:2.61= 1.3841 hrs.
The time taken by the dam surges to reach Bangalore from Kamchatka quake epicenter is
1.3841x(5563/8354)= 0.9217 hrs.
The Kamchatka quake occurred at 3+ 5/60+38/3600= 3.0939 hrs.
The time of arrival of dam surge at Bangalore= 3.0939+0.9217= 4.0155 hrsThis is about 936 hrs IST. Police in Bangalore have said that the collapse occurred at around 915 hrs IST. This is good agreement with another TV report which put the collapse at around 945 hrs IST.
Riga supermarket roof collapse

Area of the site on 23 November 2013
Date 21 November 2013
Time 17:41–18:00 PM UTC+2
Location Priedaines iela 20, Zolitūde, Riga, Latvia
Coordinates 56°56′38″N 24°1′3″ECoordinates: 56°56′38″N 24°1′3″E
Cause Under investigation
The roof of a Maxima supermarket located in Zolitūde, Priedaines street 20 in Riga, Latvia, collapsed on 21 November 2013 at 17:41 local time. The disaster killed 54 people including three rescue workers; another 39 were injured and received medical attention. This was the worst disaster in Latvia since 1950, when the steamer Mayakovsky sank in Riga, resulting in the deaths of 147 people.
Eyewitnesses said that at around 16:21 a fire alarm was set off and there were announcements made that the store should be evacuated. Security personnel verified this to be related to welding construction in the basement and switched off the alarm. It was later reported that the owner of the company which had installed the alarm said that it was designed to detect fire emergencies. He said it is unlikely that the alarm was set off by dust from the roof starting to collapse, as it was set off near water pipes in the basement. The store's security verified that there was no fire and therefore did not carry out an evacuation, but rather treated it as a false alarm and called in a technician to turn it off. The building collapsed shortly after the technician arrived and he was not able to verify why the alarm went off. A board member of "Maxima Latvija" said that security had followed protocol, which was not to evacuate if there was no visible danger. According to some reports the smaller shops in the retail centre, unlike Maxima, were evacuated and closed down.

The belief in the truth of a law increases in direct proportion to the number of favourable instances of the law( of the cumulative effects of dams)
