The speed and effectiveness of China's response has been exceptional. A lot has been learnt from the 2008 Sichuan earthquake. What really has impressed me is the coordination between the different branches. Everyone seems to know what needs to be done, and it just gets done with full dedication. No doubt many lives were saved!
There are a few things that made this quake not as deadly:
1. Magnitude-one magnitude less means a lot less energy released;
2. Back in 2008, a whole town completely wipe off from the map, this time at least so far that didn't repeated;
3. Infrastructure damage wasn't as severe as it was in 2008. With the land roads not completely cut off, a certain level of vehicular and human traffic is still possible, though the blockages hinder the deployment of heavy machinery and supply convoys into the affected areas;
4. Timing - Saturday morning instead of a Monday afternoon after lunchtime;
5. Communications were not as cut-off as it was in 2008. Blackouts and damages to cellphone facilities are unavoidable but still localized; repairs were quick and by the 21st services in areas including the epicenter are resumed.
The response of the authorities was noticeably swifter this time round, thus far we haven't see the kind of mad scrambling.
And speaking of donations, there're some disturbing "noises" now circulating in HK, mainly from the usual "anti-government" suspects, calling people not to donate because it'd only fatten somebody's coffers, and China has more money...
