If you feel this earthquake (or if you are near the epicenter), please share your experience and submit a short “I feel it” report! Other users will be happy to hear that!
Too if you DO NOT feel the earthquake even if you are in the area please report! Your contribution is also valuable for earthquake science and earthquake hazard analysis and mitigation efforts. You can use device location or a map to show your location during an earthquake. Thank you!

Info: The more agencies report about the same earthquake and post similar data, the more trust you can have in the data. It usually takes up to several hours for earthquake parameters to be calculated with near optimal precision.
