Yes, that is common though. You have a variety of measurements, from a variety of technologies, from a variety of distances, and from a variety of sources. Given the damage a quake and tsunami can cause, especially the early measurements are estimates that later get corrected in light of new information. In Japan for example, it is very much not uncommon that early tsunami warnings are later cancelled. Yes, false alarms are bad, but the example I usually use in terms of how much time can matter is the 1983 Sea of Japan quake [1], where the tsunami hit in 12 minutes after the quake.
Lots of sources are initially approximate or conflicting, scientists consolidate and update the figures within minutes, but tabloid journalists take the highest bid
You need to wait for a story to build up to have a clear picture
I live in some area where an earthquake you can hardly feel happens every other year. Some newspapers would tell reader how it was pandemonium, because they have a new topic besides city hall plans to install a bench that's nowhere near trees
Felt it ~600KM away in a high floor, building was swaying. Others didn't feel it and at first I thought I was just [unusually] light-headed or something, but then we realized a door was swinging back and forth slightly, and a hanging plant was swaying.
I was in that earthquake. Was finally able to check in to a hotel now. It was very scary. The room was shaking for at least 5 minutes and the walls were cracking. We all ran outside, down the stairs, and waited across the street until the engineers told us to walk far away. Then the siding started falling from the building (29 floors).

Earthquakes, volcanoes, tsunamis, floods, cyclones, typhoons, floods, epidemics, poisinous Jellyfish, and a whole lot more..
I have friends from the Phillipines, and think they are truly swell - and the pics they send look awesome, but I wouldn't dream of visiting them.
