Very shallow M6.6 earthquake hits Ogasawara region, Japan
A very shallow earthquake registered by the JMA as M6.6 hit Japanese Ogasawara Archipelago at 18:22 UTC (03:22 JST) on August 16, 2018. The USGS is reporting M6.4 at a depth of 11.5 km (7.1 miles) at 18:21 and M6.0 at 18:22 UTC. EMSC is reporting M6.4 and M5.9 at a depth of 10 km (6.2 miles). According to the USGS, the epicenter was located 251 km (156 miles) SE of Iwo Jima, 420.9 km (261.5 miles) SSW of Ogasawara, Japan and 945.4 km (587.5 miles) NNW of Saipan, Northen Mariana Islands. There are no people living within 100 km (62 miles). Although there may be slight sea-level changes in coastal regions, this earthquake has caused no damage to Japan, JMA said. The closest volcanoes are Minami-Hiyoshi and Nikko, both submarine. They have located roughly 100 km (62 miles) W of the epicenter. Periodic water discoloration and water-spouting have been reported over Minami-Hiyoshi since 1975 when detonations and an explosion were als…

Two shallow earthquakes (M4.0, M4.3) hit northern Vancouver Island within 10 minutes right along the Cascadia subduction zone


Two shallow earthquakes have struck off the northern coast of Vancouver Island within 10 minutes on January 14, 2017. The first tremor (M4.0) occurred at 10:54 a.m.. About 10 minutes later, a 4.3-magnitude earthquake struck in the same area. The epicentre for both quakes was 159 kilometers west of Port Hardy, at a depth of 10 kilometers. Seismologists do not expect it to have been felt on the Island.

The Cascadia Subduction Zone is a very active region. It’s a part of the plate margin, the region between the Pacific plate and North American plate where we see hundreds of earthquakes each year. The earthquake waves tend to lose quite a bit of energy as they travel from the oceanic plates onto the continental plate, onto Vancouver Island.
