Hello David, In general, yes. However the devil is in the details.
For example, the VEI has to be sufficient to loft ash/sulfur into the stratosphere to affect climate. Since the altitude of the beginning of the stratosphere varies from about 17 km at the equator to 7 km at the poles, this VEI threshold will vary with latitude. Also, the volcanic blast must be pointed upwards, or mostly upwards. For example, St. Helens was mostly a horizontally directed blast, so no climate impacts resulted, even for a large blast. Also, the amount of sulfur in the volcanic blast can vary, dependent on the geology of the region.
