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…

These 49 giant sinkholes scattered over a 200-km area form the largest cluster of sinkholes in the world

There are at least 49 massive sinkholes scattered in a 200-km karst area in NW China’s Shaanxi. Such a high density of sinkholes is rarely seen, making this region one of the world’s largest cluster of sinkholes in the world. The following video by New China TV reports on the scientific expedition that was undertaken to understand these deep craters in the ground. And as incredible as it seems, some of the cavities represent lost worlds with their own ecoysytems, their own trees and their own animals:
Some of the giant holes in the ground are like deep caverns harboring their own endemic tree and animal species:

We still have lots of wonders to discover on our Planet Earth.
