I want to know the answer to the following question:
What is the Chinese name for a seismometer?
All the background I'm provided with is that "To better prepare for calamities, Zhang Heng invented a seismometer in 132 CE which provided instant alert to authorities in the capital Luoyang that an earthquake had occurred in a location indicated by a specific cardinal or ordinal direction.". Is that enough to answer the question?
Answer: no
