What is a Seismometer?

Some words around earth movement, technology & safety

An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air and wreak destruction across entire cities.

At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami. Earthquakes can also trigger landslides and, occasionally, volcanic activity.

In its most general sense, the word earthquake is used to describe any seismic event—whether natural or caused by humans—that generates seismic waves. Earthquakes are caused mostly by rupture of geological faults but also by other events such as volcanic activity, landslides, mine blasts, and nuclear tests. An earthquake's point of initial rupture is called its hypocenter or focus. The epicenter is the point at ground level directly above the hypocenter.

A seismometer is an instrument that responds to ground noises and shaking such as caused by earthquakes, volcanic eruptions, and explosions. They are usually combined with a timing device and a recording device to form a seismograph. The output of such a device—formerly recorded on paper or film, now recorded and processed digitally—is a seismogram. Such data is used to locate and characterize earthquakes, and to study the Earth's internal structure.

Seismometer App measures how an earthquake is felt in a certain area, based on the relative effects of an earthquake on structures and surroundings. Seismometer app uses scales that correspond to movement intensity and not magnitude.

This app will run at your command and set an appropriate alarm so to inform you that an earthquake is occurring. It is a really handy function for places with a lot of earthquakes, and really useful especially when sleeping when every little second counts for your own safety.

An app that can possibly save your life.

Features

You afraid if an earthquake will occur? Have this function by your side and be alarmed instantly. An awesome tool for your safety.

PROTECTION

Seismometer will alert you of an earthquake as you can feel it exactly where you are.

LIFESAVER

While at sleep? Will wake you up and save crucial seconds of action. A true lifesaver.

ALGORITHM

A special designed algorithm senses the motion of the device and converts it into earthquake movement intensity.

DESIGN

Continually improving design, to make it easier and handier.

EARTHQUAKE SCALES

Cycle through the 4 major earthquake scale: USGS (USA), Shindo (Japan), Liedu (China), Mercalli (World).

HELP ON SCALES

Every scale has its shaking table. Please advise it before choosing an intensity level.

INTENSITY LEVELS

Set the level of perceived shaking (alarm) every scale has to offer.

ALARM

Instant alarm with audio & visual feedback. Press TEST button to see what happens.

Seismometer App measures how an earthquake is felt in a certain area, based on the relative effects of an earthquake on structures and surroundings. Seismometer app uses scales that correspond to movement intensity and not magnitude.

Everyone in a place where seismic activity is a frequent phenomenon.

Can alarm and save crucial seconds when an earthquake occurs - especially during sleeping. Just make sure it is working (monitoring for earthquakes)

Seismometer is a scientific equipment that can measure earthquakes. Their intensity of movement or magnitude.

Seismometer app is designed to measure intensity of movement by using device's integrated accelerometer and gyroscope.

A special algorithm translates movement into the 4 widely used earthquake scales.

A special designed algorithm translates movement into the 4 widely used earthquake scales. USGS, Shindo, Liedu and Mercalli.

As a safety feature that can be handy in a place with a lot of earthquakes. First an earthquake occurs and then you can hear it in the news or websites.

First press the second top left button in the main view
  • Select Scale
  • Press "?" button to read about the specific scale and its levels of intensity
  • Press "Test" to see and hear the alarm
  • Adjust your desired alarm level of intensity by using "+" & "-" buttons
  • It is recommended - but not obligatory - to enable airplane mode and disable wifi and bluetooth
  • Leave device on a steady surface like the floor
  • Press Play button to start
Do not use or touch your device as you will trigger the alarm

Of course it can! Can give you crucial seconds of action between the event of an earthquake and the realization of an earthquake. Experts say that 3-5 seconds of action can be the difference between life and death when a vast earthquake occurs.

Are earthquake intensity scales used by major institutes to monitor the movement and the results of an earthquake, used in various parts of the globe.

Richter scale represents earthquake's magnitude and it can not be measured by using accelerometer and gyroscope. Needs very specific equipment and expensive one. Also magnitude represents the power of an earthquake and it is crucial for scientific purposes only.

Intensity movement scales are human oriented and easier to understand and use.

Yes. Any movement of the device will be translated into an earthquake intensity movement and will trigger a false alarm.

No. Any movement of the device will be translated into an earthquake intensity movement and will trigger a false alarm.

Be aware that leaving a device with display on, will consume too much battery in little time. An iPhone 12 Pro will take approximately 8 hours to be empty.

It is recommended but not obligatory.

iPhones & iPads are the safest devices you can use, but there are rare cases where some equipment always connected to chargers malfunctioned. Especially iPads can be used as kiosks - meaning always connected to power. In any case use your equipment at your own risk as Seismometer app can not be responsible for any battery or device malfunction.

Yes. Be aware that leaving a device with display on, will consume too much battery in little time. An iPhone 12 Pro will take approximately 8 hours to be empty.

Your floor is the best place (be careful not to step on it). Also a heavy furniture with no moving surface like a heavy table.

No, not at the moment

No you do not need for the main function (monitoring). You only need internet connection to read this FAQ section or help for scales.
