About this app

Vibration meter is an app called seismograph or seismometer, which measures the strength of vibration, quakes, earthquakes, vibrations of the human body or any other objects around you.

Our app allows for detecting and recording of seismic waves generated by earthquakes, volcanic eruptions, avalanches and other sources of vibration and shocks.
Accelerometer in your mobile phone is used for detection of vibrations and measurement analysis.

Graph presents a record of the ground motion at a measuring point. Ground movement or an object is presented as a function of time in the three Cartesian axes, with the z axis perpendicular to the Earth's surface and the x- and y- axes parallel to the surface.

Mercalli intensity scale is a seismic scale used for measuring the intensity of an earthquake. It measures the effects of an earthquake and it is distinct from the moment of magnitude.
Richter Scale assigns a magnitude number to quantify the energy released by an earthquake. Peak Ground Acceleration (PGA) is equal to the maximum ground acceleration that occurred during earthquake shaking at location. PGA is equal to the amplitude of the largest absolute acceleration recorded on an accelerogram at a site during a particular earthquake.
In this app we use Instrumental Intensity Scale (developed by The United States Geological Survey) which maps peak ground acceleration and peak ground velocity on an intensity scale similar to the felt Mercalli Scale. These values are used to create shake maps by seismologists on around the world.

Mercalli Intensity Scale distinguishes the following levels of vibration and impact damage:

I. Instrumental - Not felt. Recorded by seismographs.
II. Weak - Felt only on top floors of high buildings.
III. Slight - Felt indoors, like a passing light truck.
IV. Moderate - Windows, doors rattle. Like passing train.
V. Rather Strong - Felt by all. Small objects upset.
VI. Strong - Books off shelves. Trees shake. Damage.
VII. Very Strong - Difficult to stand. Buildings damaged.
VIII. Destructive - Significant damage. Trees broken.
IX. Violent - General panic. Serious damage. Cracks.
X. Intense - Most buildings destroyed. Rails bent.
XI. Extreme - Rails bent greatly. Pipelines destroyed.
XII. Catastrophic - Near total damage.

This app allows you monitor and share the results of your measurements with other users.

Ratings and reviews

I'm trying to analyze different methods of isolating vibrations from electronic musical instruments. I tried 3 other vibration-sensing apps before this one. They all had issues, but they all registered vibrations. This one did nothing, but even when I put my phone directly on my keyboard and played. 🤷‍♂️

This has potential for improvement. Firstly by adding an option to see the recorded data visually (more than 15s). Secondarily by making it possible to record a specific length of time, giving it a way to collect data without remotely controlling the phone thru another application. Some basic guide and recommended usage would probably help anyone trying it out for the first time. Also, the frame don't scale correct, making the text describing magnitude to draw on top of each other..

A really beautiful and utility app! Even when you are not in a seismic zone! Sensitivity is top notch is Samsung's flagship phones. Registers even slight vibrations! I even use it as an antitheft alarm when am in office or napping in public transport 😁
