P2PQuake detection
Shows increased “I felt it” activity within a region. It is not Shindo and does not locate individual people.

Felt an earthquake in Japan?
See where others are reporting shaking while you look for official information. Follow P2PQuake signals and JISHINDESU felt reports on a map that updates automatically.
Community activity is not an official Shindo measurement, Earthquake Early Warning or forecast. Use JMA and local-authority information for safety decisions.

No current community activity to display
No reports does not prove that no earthquake occurred. Check official information as well.
Reconnecting
A short tone for coherent new reports; a double chime for a matched official report. Weak signals are silent. This is not a safety alert.

Isolated and low-confidence P2PQuake signals are not mapped. Coloured cells show felt reports, teal areas show more coherent P2PQuake activity, and a gold point marks an official JMA epicentre — not the extent of shaking.
If you felt shaking, make safety your first action
Move away from windows and unstable objects. Near the coast, evacuate after strong or prolonged shaking without waiting for this page or an app update.
Official earthquakes in the past hour
Confirmed reports, separate from community activity. Refreshes every 30 seconds; times in JST.
What this map shows
The two community sources are separate from JMA epicentres reported in the past hour. Confirmed matches link to official event details.
JISHINDESU felt reports
People’s experiences are grouped into hexagonal areas. Colours describe how shaking felt, not measured Shindo. Exact user locations are not displayed.
Official JMA report
When a match is found, open the earthquake report for the hypocentre, magnitude and station observations. Official data may be revised in later reports.
ADD YOUR REPORT

Felt shaking? Your questions, answered
Why did I feel shaking before an earthquake report appeared?
Community reports can arrive before official information. Reports alone do not confirm an earthquake. Keep this page open to follow new submissions and check the latest JMA reports. Do not wait for an update when you need to take action for your safety.
Do the map colours represent Shindo intensity?
No. The four levels describe subjective experiences: barely felt, noticeable, strong and very strong. Shindo is intensity measured at a station. P2PQuake signals use a separate map symbol and are not Shindo measurements either.
Why is my report not shown as a point on the map?
JISHINDESU reports are combined into hexagonal areas. An area appears once the required reporting threshold is reached, so the total may increase before a new area becomes visible. Exact user locations and individual reports are not displayed.
Does an empty map mean there was no earthquake?
No. The map shows coherent current community activity and official epicentres from the past hour. Weak signals are not drawn, and older events leave this view. Use the earthquake archive for past events.
How can I add a report?
Use community shaking reports in the JISHINDESU app. This page lets you follow incoming activity. If the system matches it to a JMA report, a link to the official event details appears in the panel. Not every report will receive a match.
