Recently, #Chile"s coastal towns felt the brunt of an 8.3-magnitude #earthquake and have now been warned about a possible #tsunami. - http://clapway.com/2015/09/17/earthquake-chile123/

The coast of Chile was recently shaken up by an 8.3-magnitude earthquake that occurred at 7:54 pm in the evening, on September 16. Several tremors followed the main quake, which set off loud sirens warning civilians about the possibility of tsunamis along the coast. Other areas, such as California, Hawaii and New Zealand, received the same warning as news of the earthquake spread. People were evacuated from their homes immediately and the current death toll is at least five.

Chile’s coastal towns – such as Coquimbo and Illapel, as well as the country’s capital, Santiago – felt the brunt of it. At one point, Coquimbo witnessed 15 foot waves, while other smaller tsunami-like waves – up to six feet – hit nearby towns. In the process, the sea level had risen, causing flooding in the coastal cities, such as Illapel, where thousands of homes lost power. Moreover, concerns were raised about how the earthquake might affect Copahue volcano, which has recently been active. So far, there have been no signs of any activity, but the area is still being monitored.

Other areas affected by earthquake

There is a possibility for a tsunami to arrive to surrounding areas and cause destruction in places like New Zealand, California, Hawaii, and some Islands in French Polynesia. However, the warning that was originally issued has since turned into an advisory, as the tsunami waves were only anticipated to be around 1-2 feet high, which would not drastically change the sea level.

Chile’s unfortunate place on the globe

Chile is centered around the most tectonic-ally active area in the world, specifically on the Nazca and South American plates, the former of which keeps continuing to move under the latter. Therefore, it is no stranger to earthquakes; in fact, it recently had a major 8.2 magnitude quake back in 2014, which took the lives of 6 people.

In 2010, an 8.8 magnitude earthquake caused the death of over 500 people due to the failure to issue a tsunami warning. Following this incident, safety procedures have been intensified and tsunami alarms are sounded right after seismic activity in the area. Chileans residing on the coast also partake in earthquake drills to prepare themselves in the event of an emergency.

Earthquake Shakes Up Chile and Surrounding Areas

The RCW 34"s Stellar Nursery Streams Champagne - http://clapway.com/2015/05/27/the-rcw-34s-stellar-nursery-streams-champagne-123/

new star is born in the Orion Nebula. Images of the nebula offer a view of what can be referred to as stellar nursery. This view can help researchers better understand the phases of stars, birth and evolution. The birth of a star is something to celebrate so crack open your champagne bottles and let it flow into space because this is a champagne flow seen around the world. The RCW 34’s stellar nursery is something worth celebrating.

Flowing Like Sparkling Champagne

The RCW 34’s stellar nursery is the brightest region that glows within the nebula itself. It is heated dramatically by gas and young stars can expand through the cooler gas. Once the heat reaches the borders of the gas cloud, it bursts outward like an uncorked champagne bottle. This is exactly where this process gets its name. The Champagne Flow forming in the RCW 34’s stellar nursery seems to have several star formations within the same cloud.

Views of RCW 34’s Stellar Nursery From the ESO

The image from the European Southern Observatory (ESO) Very Large Telescope (VLT) placed in Chile shows a red cloud of glowing hydrogen gas. Behind this gas is a collection of blue foreground stars. In addition, a group of massive, yet young stars are hiding in the brightest part of the cloud. The stars can affect the nebula dramatically; exposing the gas to strong ultraviolet radiation makes it so the electrons have actually escaped the hydrogen.

Space Photographers Love Hydrogen Red

Hydrogen creates a popular picture when it comes to cosmic photographers because it glows extremely bright with its characteristic red color. This can distinguish many nebulae and can allow photographers to create beautiful and bizarre images and shapes. Most importantly, it is the absolute raw material that causes the champagne flow. Ionized hydrogen is also an indicator of regions that are star forming.

When gas clouds collapse, stars are born. This usually occurs in abundant regions with a large amount of gas just like the RCW 34’s stellar nursery. Because of this, the nebula is where stellar birth and evolution come from. Dust within the nebula can easily block out the inner workings of a stellar nursery. It usually takes place deeply embedded in the clouds. Astronomers can use infrared telescopes such as the VLT to peek through the dust and study the stars.
