July was a bad month for amusement parks.

Early last month, a popular pendulum-style ride at an amusement park in the western Indian city of Ahmedabad went horribly wrong.

On Monday afternoon, a chilled day at a waterpark in Longjing, China descended into chaos when a wave machine malfunctioned in the wave pool.

Dozens were injured when a giant wave came crashing down on the hundreds of people in the wave pool, with such force that it sent water cascading over the edge.

They’re now calling it the “tsunami pool”.

Here’s Business Insider:

City officials from Longjing announced that 44 tourists were injured in the unexpected swell, and that the pool is closed for investigation, The South China Morning Post reported.

A viral video of the incident shows hundreds of people inside the wave pool at the Yulong Shuiyun Water Park, when an immense surge of water builds up near the back of the pool and slams down on the people inside.

The resultant video has gone viral:

Rumours have circulated that the wave operator had mistakenly set the wave controls to the maximum setting, but it’s more likely that it was caused by a power issue in the control room.

“According to the initial stages of the investigation, the incident was caused by a power cut that damaged electronic equipment in the tsunami pool control room, which led to the waves in the tsunami pool becoming too big and injuring people,” a Longjing city announcement said, according to The South China Morning Post.

Here’s the incident from another angle:

39 of the injured people have been discharged from the hospital. The remaining five are still in the hospital due to rib or foot fractures.
