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…

Asteroid 2018 BD missed Earth by just 0.10 LD on January 18

Asteroid 2018 BD missed Earth by just 0.10 LD on January 18

A newly discovered asteroid designated 2018 BD flew past Earth at a very close distance of 0.10 LD / 0.00026 AU (~38 895 km / 24 168 milesat 15:43 UTC on January 18, 2018, some 7 hours after it was discovered. This is the fourth closest approach to our planet since 2017 EA on March 02, 2017, 2017 GM on April 4, 2017, and 2017 UJ2 on October 20, 2017.
Asteroid 2018 BD was first observed at 08:24 UTC on January 18, 2018, at Catalina Sky Survey. This is a very small Apollo asteroid with an estimated diameter of 2.5 to 5.5 m (8.2 to 18 feet).
It flew past Earth at a very close distance of 0.10 LD at 15:43 UTC today, according to data provided by CNEOS. The Minor Planet Center has this asteroid flying past us at 17:27 UTC today.
This is the 3rd known asteroid to flyby Earth within 1 lunar distance since the start of the year and the 56th since January 1, 2017. It comes just one day before the close approach of asteroid 2018 BC, discovered on January 17.
Its next close approach to our planet will take place at 20:37 UTC on November 19, 2018, at 0.33 AU. However, it won't come nearly as close as it did today for at least 115 years.
