| time | Time (UTC) | datetime | Origin time of the earthquake in UTC. |
| place | Location | string | USGS description of the location, relative to the nearest named place. |
| magnitude | Magnitude | number | Event magnitude as reported by USGS. |
| mag_type | Magnitude type | string | Magnitude scale used, e.g. mww (moment magnitude), mb (body-wave), ml (local). |
| depth_km | Depth | number · km | Depth of the hypocentre below the surface, in kilometres. |
| latitude | Latitude | number · ° | Epicentre latitude in decimal degrees (WGS84). |
