My friends, there has been another earthquake in Sudokutown

In the epicentre was a read-out of 9.0 on the scale of Richter.

Earthquake Sudoku Rules apply.

All cages are Richterscale read-outs (like 6.8 or 4.1, for instance) and they sum to the digit within the cage, or a to be determined digit. These read-outs are read from left to right, or top to bottom. Read-outs can not be repeated in cages.

Furthermore, there are 4 rings around the epicentre where read-outs are done. Read-outs in rings closer to the epicentre must be higher in value than those in rings further away from the epicentre.

So far, the rules are the same as the first earthquake. If you haven't tried it. Here is the First earthquake , which is much easier.

After this new earthquake, skyscrapers have collapsed. The ones that remain standing have to be determined by the following principle:

In a 1-cell radius around a full read-out a skyscraper will collapse if the skyscraper's value would sum to 10 or higher, combined with the first digit of the read-out. The digits that make up the read-out are also skyscrapers and are influenced by themselves. They will collapse if they would sum to 10. (A 5.4 would destroy the 5, but not the 4)

Example:



The digits highlighted in red will have collapsed. In this case 3 is the first digit, so everything higher than 7 will collapse.

Digits outside the grid indicate how many skyscrapers can be seen standing after the earthquake, seen from that direction. Example:



From the left, 1,2 and 5 can be seen, resulting in a 3. From the right 4 and 5 can be seen, resulting in a 2.

Thanks to Wecoc for mentioning skyscrapers. Highlight conflicts should be turned-off in the Settings! Good luck!
