Magnitude 5.5 earthquake near 35 km WNW of Pante Makasar, Timor Leste
Date: 2026-04-21
Time: 03:17:07 UTC
Location: 🇹🇱 Timor Leste
This quake occurred in a seismically active region near the boundary of the Australian and Philippine Sea plates. The moderate depth and magnitude suggest it resulted from normal faulting associated with regional tectonic stress. No tsun
Magnitude 5.4 earthquake near 11 km NW of Cotacachi, Ecuador
Date: 2026-04-21
Time: 02:22:20 UTC
Location: 🇪🇨 Ecuador
This quake occurred in a seismically active region along the subduction zone where the Nazca Plate is being forced beneath the South American Plate. The depth of 118.5 km suggests it originated within the subducting plate, typical of intermediate-dep

Our seismograph is still trembling from this morning's M7.4 off Japan — our USGS equipment captured every wave. Tsunami threat cancelled, but the ground is still shaking. Almost like the planet is putting on a show for our special guest! Earthquake expert Professor Alan Kafka joins us IN PERSON tomorrow, Tuesday April 21 at 8pm at Westport Observatory.

Magnitude 7.4 earthquake near 115 km ENE of Miyako, Japan
Date: 2026-04-20
Time: 07:52:56 UTC
Location: 🇯🇵 Miyako, Japan
This quake occurred along the Japan Trench, where the Pacific Plate subducts beneath the Okhotsk Plate, causing frequent strong earthquakes. The shallow depth (10 km) suggests it originated near the surface, likely from crustal deformation.
