In these cases, magma is shallow and the water and gas which is trapped below the surface affect surface and groundwater to form vigorous hydrothermal systems. Sometimes, the signs can last for weeks, as at White Island, but sometimes they happen too close in time to the explosion to be taken for warnings.
