Kunashir, is there anyone alive?

Today, Japan proclaimed the Kuril Islands its territory . I won’t talk about politics. It became interesting for me to consider the islands of Iturup, Shikotan, Kunashir from space on Google Maps. The new Google Maps is equipped with Historical imagery, where you can see pictures taken at other times. In general, I discovered that the 2009 Kunashir slides are a bit of a “blurred” 2004 slides. I found a couple of cars - not a single one in five years has moved. Vessels also don’t float, they stand like in 2004. It is a striking fact that the clouds have not moved since 2002. Can someone explain - there is generally no movement there and it should be so, or is Google still making something secret?
