Prabhath Sajeepa, a 48-year-old tech worker from California's Bay Area, has been confirmed as one of the Americans missing following catastrophic floods along the Nepal-Tibet border. The disaster, which began Wednesday, has resulted in at least 530 fatalities and left over 1,500 people unaccounted for.

Sajeepa was traveling with the Isha S3 group, a spiritual organization led by guru Jaggi Vasudev. His brother, Praneeth Kumar, shared on Facebook that the family has had no contact with Sajeepa since the event. Sajeepa's niece told the BBC that he had been involved with the foundation for years and expressed hope for his safety.

Jaggi Vasudev stated in a video on his YouTube channel that approximately 80 members of the group were missing after the flood, describing it as a "terrible and extraordinary event." The Isha Foundation reported on social media that a group of their members was caught in the flood while at an immigration office. Video shared by the foundation shows people fleeing the building moments before it was inundated with mud, dust, and rocks.

Kumar indicated that Sajeepa's last known location was near the Gyirong immigration port. According to his LinkedIn profile, Sajeepa is employed as a technical director at Pure Storage. He resides in the San Francisco Bay Area.

Other Americans are also missing in the region. Deepak and Madhu Ahuja, from Texas, were on a pilgrimage to Mount Kailash and have not been heard from. Their daughter, Ashna Ahuja, has been seeking updates from officials and people on the ground, but has received limited concrete information. Ramesh and Neelam Sharma, a couple from New York, are also unaccounted for after traveling to the area for their own pilgrimage. Their daughter, Dr. Radhika Sharma, stated that her parents' journey was their first vacation alone since retiring.

Nepali police reported on Friday morning Eastern Time that authorities were actively engaged in collecting bodies, identification, and disaster management efforts. Images released by the department showed the destruction and rescue workers assisting survivors.

The severe flooding was preceded by seismic activity along the Nepal-China border around 8:30 a.m. local time. The U.S. Geological Survey initially registered the event as a magnitude 5.2 earthquake but later determined it was caused by a massive glacial collapse. Scientists described the event as an "extremely powerful glacial collapse and debris flow that caused subsequent catastrophic impacts downstream." A large chunk of a glacier disintegrated into a fast-moving mixture of water, ice, debris, and rocks that surged down the Lende Khola River, overwhelming communities.

President Donald Trump stated on Thursday that the U.S. had offered Nepal any necessary assistance and was sending aid. A geologist from Tribhuvan University in Kathmandu described the disaster as a "tsunami from the sky."
