there was volcanic activity in every time period exept for the ones of water
The end of the Silurian period and the beginning of the Devonian period was not defined by an extinction event, but by the distinctive rock formations of the period. As a result the end of the Silurian period is uncertain by +/- 2.8 million years.
There are no active volcanoes in the State of Georgia. Currently, (November 2104) the only active volcanoes are in Hawaii. There are a number of currently dormant volcanoes in Alaska, California, Washington, Oregon and Wyoming. These could become active at any time,
No. Ganymede does not have any volcanoes.
Saturn does not have any volcanoes.
Iraq experiences earthquakes but does not have any volcanoes.
Volcanoes can erupt at any time of year.

Volcanoes can erupt any time of year, there is no volcano season.

The Australian mainland doesn't have any active volcanoes at this time because it doesn't lie over any plate boundaries. Also, it isn't over any hot spot in the mantle at the present time. It has had volcanic activity in the past.
Without qualification a time period is any amount of time, to define the period, additional information is required, such as 'a time period of 20 years'
There are rare Diacalymene species from both the Silurian of New York & Oklahoma.
