The famous volcano in front of The Mirage will be reducing the number of times it erupts per night. The volcano showtimes will be 8 and 9 pm on weekdays (Sunday through Thursday) with an additional 10 pm show on weekends (Friday and Saturday).
Previously the volcano had erupted every half hour from dusk until midnight. It has operated since the hotel opened in 1989. The volcano was upgraded in 1996 and underwent another major renovation in 2008.
Unfortunately this marks another reduction of free attractions on the Strip. The MGM Grand lion habitat,the Pirate Show at Treasure Island, and the Rio Show in the Sky were some other free attractions that closed recently. While the volcano isn't closing completely it's upsetting nonetheless.
It appears MGM Resorts International is reducing the volcano's hours as a cost cutting measure. MGM has also been selling assets recently. It seems like they need money for something. I guess they are watching their pennies closely with the $1.2 billion MGM National Harbor starting construction, along with Massachusetts and Macau projects underway.
