The ocean boiled, the earth turned to liquid and the demise toll in Indonesia remains to be rising.
It is simply one in all many, many occasions the nation has confronted demise and destruction after a tsunami has caught following an earthquake. Why is it so onerous to foretell these pure disasters?
Is complacency and poor planning the best impression on lack of life?

Indonesian in earthquake today at 1.44 am
You all need to look up Dutchsince on YouTube. Regardless if you want to believe it or not, he straight warned about the US most recent alarming quake off shore of OR just YESTERDAY!
Just to clarify, the San Andreas run just a bit to the east of where I live and on land. It only goes off shore near the very northern part of the state of California, where it changes from a fault that slips side to side to a subduction zone called the Cascadia Subduction Zone. The San Andreas does produce slow earthquakes in the creeping region around the middle of the state. It's basically like when you go to break a stick and you hear some small cracking sounds before the things breaks. It's just small sections of the fault slipping without causing a huge section to slip really fast. It reduces stress in the local region but, since energy is neither created nor destroyed, this stress is transferred to neighboring sections of the fault, some of which do tend to break in big earthquakes. Then we have tons of faults that have splintered off near the San Andreas Fault here in Southern California so we have all kinds of faults that can produce 7s around here. Hell, I've felt probably 4 such earthquakes.
The satellite data does give us some idea of where the strain has been placed on the earth and aftershocks generally occur in the area surrounding the main shock that has been strained. It's not predictive, but it can help make a decent forecast of where the aftershocks will occur.
I can't believe you never go to what to do during an earthquake! So, if the ground gets to shaking, get under something sturdy, cover your head and neck, and hold onto whatever you got under. You can also go into an internal hallway if there's nothing to get under, but be careful of closets that might have electrical equipment, central air units, hot water heaters, or other things that might be heavy and fall out onto you (preferably you would have bolted them to the wall but this is what to do at the moment of the earthquake). Whatever you do, don't run outside because, if anything does fall on the building, it's going to be on the outside, even if it's only the glass from windows. Once it stops shaking, then you can go out. If you think there has been any major damage to your building, you should go out and, if you can, turn off the gas to the building because gas leaks are one of the big reasons for devastating fires after an earthquake.
Now, if you're in California and you feel strong shaking, there almost certainly will be no tsunami as most of our faults run on the land and move to the side instead of one plate going under the other. If you are in the very northernmost part of California or in Oregon or in Washington or near the ocean anywhere in the ring of fire earthquake area around the Pacific Ocean, there might be a tsunami. If you are in one of those areas and you feel strong shaking, wait until the shaking is over if you are inside and, if you are outside, run to the hills… literally. Don't try to escape in your car. Go immediately to the highest ground in the area. Worst case scenario, a tsunami will come but you will be watching it from ground that is high enough so the wave doesn't get up that high (some tall buildings are safe too but, unless you are in Japan and everyone else is running to that building, get on high ground). If no tsunami comes, congratulations, you have gotten some excellent cardiovascular exercise running up the nearest hill. Be careful, though, the tsunami won't necessarily come immediately after the earthquake because it depends on how far out to sea the earthquake happens. The wave will travel in from wherever the epicenter was because that's where the earthquake got the water to sloshing. Also, there are always more than one wave when there is a tsunami and the waves are of pretty random sizes (as in a bigger one can come in after a smaller one and vice versa). Now, if you are in the Cascadia Subduction Zone area (very northern part of California, Oregon, Washington, and Southern Canada), the fault is pretty close to shore so you might want to make sure, if you waited for the shaking stopped to leave a building, that the tsunami isn't already coming in. The last thing you want to do is go down and out of a building just to meet up with the tsunami. It would probably be better to stay put then if your building is particularly close to the ocean. When it doubt, do as the natives do (unless they panic because panic isn't helpful during an earthquake or a tsunami).
So the main thing during the shaking is to make sure that, if things fall they don't fall directly onto you and that you are in a part of the building that is less likely to fall (the middlemost portions of buildings are usually the best unless it's a warehouse store, in which case you only hope the earthquake isn't big enough to bring the building down). Then, if there are tsunamis in that part of the world, go to high ground as fast as you can once you have made sure that nothing can fall on you. Like I said, if you're outside when the earthquake strikes, run for the hills, and also be happy that you get to experience the earthquake without the risk of a building falling on you in the process. Do avoid cars if you are outside during an earthquake because the earthquake will be moving the cars pretty significantly and you wouldn't want the cars to trap you after you've already had the fortune of being outside for the earthquake. Also, under no circumstances will the ground swallow you up, even if you see cracks in the ground and even if you see sand and water coming out of those cracks. You won't fall into the sea (unless you were on the edge of a sea cliff and a massive earthquake makes you fall off the cliff. If you are outside, you might see some pretty crazy stuff happen around you, but your only real danger is that the earthquake might shake so much that you fall on your ass. During the Ridgecrest 7.1 earthquake, I had a friend who went to get off the sofa to go somewhere safer and the earthquake made him fall on his ass on the sofa again. It usually rather comical in retrospect.
