A new phone app uses vibrations from smart phones to warn people about earthquakes.

They said they created a worldwide warning system that would _______ people and give them time to prepare. The MyShake app is _______ only for Android phones.

Smart phones are _______ accelerometers (加速度感应器). These instruments measure movement, like that of a car or airplane. MyShake uses phone accelerometers to measure seismic (地震的) activity. It has been _______ to know the difference between normal activity and earthquake movement. The software developers say their app is right 93 percent of the time.

A smart phone sends seismic information to the app developers. If the developers receive several notifications _______, it recognizes that an earthquake might be taking place or will take place soon.

Using information sent from the app, the network then _______ the   location and strength of the quake in real time. MyShake can record magnitude 5.0 earthquakes at distances of 10 kilometers or less.

MyShake uses very _______ power, according to its developers. Only when   seismic activity is   _______ by the app does it become active and sends data to the network. The app works best when your phone is resting on a ________ surface, like a table.

The developers hope that MyShake can add to information collected by the U.S. Geological Survey. That U.S. agency has created the Earthquake Early Warning System, also ________ EEW. The EEW has deployed (部署) sensors for measuring quakes in many areas.

In places where no such equipment ________, MyShake may be the only method of   early quake ________.   The app also shows ways to stay safer during an earthquake. The developers say it will become more effective as more people use it.

“Our goal is to build a worldwide seismic network and use the data to________ the effects of earthquakes on us as individuals and on society as a whole,” say the researchers.
