M5.0 Earthquake Near 三陸沖 Draws 111 Felt Reports
JMA Japan reports M5.0 near 三陸沖, with a 10.0 km catalog depth and 111 felt reports.
The event began at Thu, 01 Oct 2026 17:17:00 GMT. JMA Japan reports magnitude 5.0, 10.0 km catalog depth, and coordinates 39.900, 143.200.
The catalog location label is 三陸沖; no separate nearest-city field was supplied with this solution. By catalog depth, this is a shallow event. The magnitude-derived energy estimate is 2.00e+12 joules, or about 477 tons of TNT equivalent; that calculation describes source energy, not local damage.
111 public felt reports are attached to the current catalog entry. Other attached observation fields include reported intensity 2. No official casualty or damage statement is attached to the normalized event evidence.
The JMA Japan catalog currently marks the solution as reviewed. Solution-quality fields list 111 reporting stations. Other agency solutions retained for this same origin are USGS Week M5.1; EMSC Global M5.1. These are alternate reported solutions, not additional earthquakes.
The issuing source also supplied this event summary: Maximum JMA intensity 2. この地震による津波の心配はありません。 The linked event record should be checked for later magnitude, depth, location, and review revisions.
