Is it possible for a city to be located 30 degree N 150 degree W explain?

Yes, a city can be located at 30 degrees North latitude and 150 degrees West longitude. This coordinate points to a location in the Pacific Ocean, roughly east of Australia and west of the United States. While there may not be a major city at that exact point, smaller settlements or research stations could exist nearby. Therefore, while it's geologically feasible, it may not correspond to a well-known urban area.
