What is a significant impact of the recent volcanic eruption in Kamchatka?

The significant impact of the recent volcanic eruption in Kamchatka primarily relates to air traffic disruption. Volcanic eruptions can release large amounts of ash and gases into the atmosphere, which can severely affect air travel. Ash clouds are particularly dangerous for aircraft, as they can damage engines and pose threats to safety. Consequently, flight cancellations and rerouting become necessary, resulting in significant disruptions in air travel within and around the affected region.

In this context, while other options might seem plausible, such as an increase in tourism or improvements in local agriculture, they do not accurately reflect the immediate impacts observed following a volcanic eruption. The primary concern following such events tends to be the safety and operational issues that arise in the aviation sector due to airborne volcanic materials. This is a well-documented consequence of volcanic activity, making air traffic disruption a significant and immediate consequence of the Kamchatka eruption.
