No passenger has ever died on the Japanese Shinkansen, but a train was derailed during an earthquake. The safety of high-speed trains, both in Japan and elsewhere, also relies on safety during a derailment by keeping the train rigid and having steel cars. In contrast, it seems to me that a breach of the integrity of the hyperloop tube would probably be fatal. Also, the higher speed of a hyperloop makes automatic stopping take longer.

In all, the hyperloop as it's currently being presented is much more dangerous than high-speed rail during an earthquake, and this is a legitimate concern.
