Anjana Raja, a California resident, recounted her experience surviving a devastating landslide flood in Nepal that has claimed hundreds of lives. The disaster struck while Raja and her husband, Pattabiraman Venkatesan, were on a spiritual journey to Mount Kailash.

While traveling by bus toward the Chinese border, Raja observed the bus driver and front passengers fleeing the vehicle. She then witnessed a massive landslide descending towards them. "It was water mixed with the mud that was a good 50 to 60 feet high. It stood like a serpent right there staring at us," Raja told ABC News. "Like a cobra's head staring at you."

Reacting instantly, Raja grabbed her husband by his collar and urged him to flee the bus. "I grabbed him by the collar, and I said, 'Run, we need to go right now,'" she recalled. "I didn't even give time to act. I just said, 'Leave the bus right away or we're gonna die.'"

The couple, along with other passengers, ran to a nearby camp and sought higher ground as the floodwaters inundated the streets. Raja described the chaotic escape: "We just blindly...climbed. We didn't even know what direction ... There was no guide for us, there was nobody, we were just frantically running. Running, literally running. It was slushy, it was muddy, we were climbing rocks, which was slippery. We just ran for our life."

From their vantage point on the third level of the camp, they watched as the floodwaters engulfed their bus and carried away vehicles, debris, and people. "It just came like a roar, it sucked a bunch of buses, SUVs, people, the basecamp, everything -- took it in, turned it, turned it all upside down and dumped it into the ground," Raja said.

As of Friday, the Nepal National Disaster Management Authority and the Chinese government reported 584 deaths and over 2,400 missing individuals due to the floods. The couple was eventually able to contact their daughter in California, Amanda, and have remained in communication.

Raja expressed gratitude for the first responders, noting their focus on aiding all victims, regardless of nationality. "What I really loved is his focus was not foreign nationals, nor U.S. citizens. He looked at us as humans," she said of her rescuer.

Despite the traumatic experience, Raja stated her determination to complete her spiritual journey to Mount Kailash. "I am determined to," she said.
