Given that the eruption of Mt Lamington occurred long before written records or human habitation, it is unknown, but unlikely whether it came as a shock.

There was no specific warning issued before the Krakatoa eruption in 1883. The event happened suddenly and caught people by surprise, resulting in a devastating disaster.
That depends upon the builder
Nothing really, it was there long before the Romans ever came to Britain.
Yes, Santa Maria volcano in Guatemala was considered dormant before its significant eruption in 1902. Prior to this eruption, it had not shown any major volcanic activity for several centuries. The 1902 eruption was one of the largest in the 20th century, leading to widespread ashfall and changes in the landscape. Its awakening surprised many, as it had been relatively inactive for a long period.
Before you ask the questiion how long did it take to build, you must first ask yourself, "did they have enough financial support to build the International Finance Center?"

The time it takes for magma to heat up before an eruption can vary significantly depending on several factors, including the type of magma, the geological setting, and the conditions within the magma chamber. In some cases, magma can accumulate and heat over thousands to millions of years before erupting. In other scenarios, changes in pressure, temperature, or the influx of new magma can trigger an eruption after just a few days to weeks. Ultimately, predicting the exact timing of an eruption is complex and depends on the specific dynamics of each volcanic system.
A volcano rumbles for approximately 5 minutes and 25.3 seconds before erupting. It then continues to slightly rumble whilst the eruption is going on.
