Frequently Asked Questions

This FAQ is for both the EQ Report iOS and Android applications. The differences between EQ Report iOS and Android versions are so minor that this FAQ can easily be used for both. If differences apply, they will be mentioned below.

The app can be used both in portrait and in landscape mode. The landscape mode facilitates reading our in depth reports from important earthquakes.

Main buttons at the base of the screen

MAP
Screen Shot 2018-02-13 at 14.25.33
The Map button shows a world map with the latest string of earthquakes. The balloons differ in size. Smaller balloons for minor earthquakes. Really big balloons for massive earthquakes. Clicking on a balloon shows the Magnitude and depth of that earthquake, the 2 most important parameters. The 3 most recent earthquakes have green balloons. The world map can be pinched with 2 fingers.
The double bullet red/orange icon on the upper part of the screen can be clicked to reach our alert/pre-alert screen. The screen shows the countries who have an unusual increase in visitors which in many cases indicates a felt earthquake. After a very strong  earthquake many countries can be listed as people from many parts of the world are accessing our site.  When the increase stabilizes or when the number of visitors drops again, the country will disappear from the list. As this page is no exact science, false alerts are a possibility.

I FELT IT

Clicking on this button bring up a form to share your experience with other users and with professional geologists and universities. EQ Report is only interested in your shaking experience, not in your personal data.
The system may ask you to agree with your locations setting. If you accept, a green button will come up and if clicked will fill up your location at thge time of consulting the app. You can overrule it and manually correct your address.

Uexp
Screen Shot 2018-02-13 at 14.24.55
Uexp is the abbreviation we have chosen for "I FELT IT User experiences". When you felt an earthquake and your earthquake has not yet been listed, this is the location to check whether other people have not been send a I FELT IT report for the same earthquake. If not, be the first to do so via de I FELT IT button at the bottom of this screen.

LIST
Screen Shot 2018-02-13 at 14.24.40
Earthquake data is arriving at different intervals. Sometimes fast after the shaking and at other times hours later.
The standard order of our list is "following the time of occurrence", the last occurred ones on top.
Clicking on the 2 arrows will give you the possibility to change the order into "as reported by the seismology agencies".
Sometimes earthquakes are being reported many hours after they occur.
Clicking the Clear button will wipe all the earthquakes from the screen to create a fresh buildup of new earthquakes
The double bullet red/orange icon on the upper part of the screen can be clicked to reach our alert/pre-alert screen. The screen shows the countries who have an unusual increase in visitors which in many cases indicates a felt earthquake. After a very strong  earthquake many countries can be listed as people from many parts of the world are accessing our site.  When the increase stabilizes or when the number of visitors drops again, the country will disappear from the list.

--------------------
MAP button - shows the epicenter of that particular earthquake as well as eventual other earthquakes who occurred in the same area.
The blue bullets are our I FELT IT experience reports from our users (both website and app users).
I Felt It button - If you want that your 'user experience' will be located below the corresponding earthquake, this button should be clicked.
Using the general "I Felt It" button at the bottom of the app will send your user experience to "I Have felt a NOT listed earthquake" in the website. This button should only be used shortly after the earthquake and before the listing of the earthquake you felt is active.
If you respond to an already listed earthquake, the I Felt It button below that earthquake is your place to be.
Uexp - The "I FELT IT User experiences" for this particular earthquake with those from our app users on top, followed by those from the website.
If Uexp turns red and shows a number it means that users have left an I HAVE FELT IT user experience for that particular earthquake. The number tells us how many there are. Uexp in black is empty.
Nothing reported yet?, be the first to send  us your I FELT IT user experience by clicking the I FELT IT button at left of the same earthquake.
More Info - 4 colors / black: standard page with historic earthquakes around the epicenter / blue: means that we have manually added info for what we think is a not dangerous earthquake / Orange: manually added info for what we consider a dangerous earthquake / red: manually added information for what we consider as very dangerous for damage/injuries/fatalities. Colors can change based on earthquake and/or damage data.
Screen Shot 2018-02-16 at 12.17.43A/PA button - Abbreviation for Alerts and Pre-Alerts. The (to be clicked) button is at Top-Right of the List screen. See below for what it does, bot on the active screen as for the notifications it can send out.

SETTINGS
Screen Shot 2018-02-13 at 14.24.14
General
: whenever you change a parameter of your settings you will be prompted to SAVE them when exiting the settings tab
Sound : select your notification sound and try the sound out with the white arrow in the green box.
Magnitude : slider from M2.5 to M6 in steps of 0.5. Why M2.5 (in fact M2.7 at this moment) as lowest? Mainly because otherwise you will get almost constant alerts and additionally because earthquakes of less than M2.7 are not al all dangerous. Originally the scale started from M3.0 but we have added a selection to M2.5 although we have activated only until M2.7 mainly to reduce the load on our servers. New servers will be coming the next couple of months and a further decrease to M2.5 may be possible at that time. We will keep you updated here.
Depth : The depth of the hypocenter or breaking point inside the earth. Only earthquakes of 200 km or shallower are well felt and maybe possibly dangerous. The slider has steps of 50 km. Depths of 500 km or deeper  will show you sometimes Magnitudes of M7 or even higher which are being felt above the epicenter as gentle wobbling.
Selected Regions : (only free at the start and for a very limited fee thereafter) We have introduced this item to not overload people with earthquakes they are not interested in. For example someone in the USA who want to be informed about all earthquakes of M3 is not necessarily interested in earthquakes of M3 in Turkey or in Chile. Important earthquakes of M6 or higher will arrive whatever limited regions the user has selected.  As the selector in the app is not showing enough details, please check the detailed maps of every region
Notification Night shift : Default button is OFF or 24 hour notification alerts. In the ON position, Alert notifications will not be send in between 10 PM and 7 AM (22:00 - 07:00)

Why are Magnitudes for the same earthquake sometimes different?
Every seismological agency reports what their instruments and seismologists have acquired.  We report what we receive from the agencies. Depending on the Magnitude and the source of the data, different Magnitude scales can be used and can relate in different numbers.

Why are epicenters for the same earthquake are different?
For the same reason as for the Magnitudes. Every agency calculates at best the epicenter. More instruments means more precise data. Local seismological agencies (who are managing their own network of instruments) are mostly, but not always, more accurate.

Why are some earthquakes double listed in the app?
We try to avoid doubles but as we use different data sources, the time of the earthquake sometimes differs a number of seconds. If the time of the earthquake is exactly the same, our system will list the earthquake only once.
