The given diagrams illustrate the position of a volcano and the transformation of a nearby village after an eruption.
From an overall perspective, the village has undergone significant changes. Notably, the transition from inactive state to active condition of the volcano results in the alteration of both population density and the surrounding environment.
Initially, the volcano is bordered by the ocean and located on an isolated island, which contains a village with some houses. Before the eruption, the aforementioned village comprised multiple houses, with some tropical vegetation such as palm trees. These facilities are around the volcano complex.
Following the eruption, the state of the volcano is active, and lava flows down the village and forms a lava river. Subsequently, various accommodation complexes are burned and demolished, while the housing arrangement remains unchanged. In contrast, the plantations in this region are likely to develop more, which can be due to the minerals or nutrients from the lava river.
