Very strong M7.3 earthquake hits Venezuela at intermediate depth
A very strong earthquake registered by the USGS as M7.3 hit near the coast of Sucre, Venezuela at 21:31 UTC on August 21, 2018. The agency is reporting a depth of 123.2 km (76.5 km). EMSC is reporting M7.3 at a depth of 112 km (69.6 miles). According to the USGS, the epicenter was located  20.9 km (13.0 miles) NNW of Yaguaraparo, 38.4 km (23.9 miles) ENE of Carúpano (population 112 082), 69.4 km (43.1 miles) WNW of Güiria (population 40 000), 107.6 km (66.9 miles) ESE Porlamar (population 87 120) and 109.1 km (67.8 miles) ESE of La Asunción (population  35 084), Venezuela. There are 560 000 people living within 100 km (62 miles). Based on all available data, there is no tsunami threat, PTWC said. Some 52 000 people are estimated to have felt very strong shaking, 2 089 000 strong, 2 587 000 moderate and 3 928 000 light. Buildings were evacuated in the capital Caracas and people fled homes. Shaking was felt as far away as …

NASA says 5 ‘close’ asteroid flybys will take place today 4/29/18

Incoming!: NASA says 5 ‘close’ asteroid flybys will take place today

The Earth will experience a number of (relatively) close calls in one day, as NASA reports that an alarming total of five asteroids will hurtle towards – but happily not quite at – our planet.

The series of space rock flybys begins at 10:29 UTC Sunday as asteroid 2013 US3, traveling at a respectable 7.69 km/s (27,646 kph) with a diameter of between 160-360 meters whizzes past us. For comparison, the Eiffel Tower measures 324 meters from ground to tip.
Next up are asteroids 2018 GO4 and 2018 GY1, which are expected to scream past us at 12:34 and 18:20 UTC respectively.
Asteroid 2018 GO4 measures approximately 30-68 meters (between three and six school buses in diameter) and have a brisk pace of 8.57 km/s. Meanwhile, 2018 GY1, on the other hand, won’t be hanging around our neck of the galactic woods for long given that it travels at a whopping 16.69 km/s, despite measuring 100 and 230 meters in diameter.
Closing the day’s near orbit rock show will be asteroid 2028 FV4 at 19:13 UTC (at 6.52 km/s) followed two hours later by 2002 JR100 at 21:15 UTC (7.68 km/s), both with a diameter of roughly a Boeing 747 (between 60 and 71 meters). Thankfully, the rocks are projected to hurtle past us at the relatively safe distance of 3,870,720 km (roughly 10 times further away than the moon is from Earth), so we needn't worry too much.
Should similar space rocks come a little too close for comfort, NASA is working on inventive ways to make sure we don’t go the way of the dinosaurs, including nuclear detonations and intense laser blasts.
