Ring of Fire was due. In 2000, the ERLAWS system was installed on the mountain to detect such a collapse and alert the relevant authorities. The Auckland volcanic field on the North Island of New Zealand has produced a diverse array of explosive craters, scoria cones, and lava flows. Currently dormant, the field is likely to erupt again with the next "hundreds to thousands of years", a very short timeframe in geologic terms. The field contains at least 40 volcanoes, most recently active about 600 years ago at Rangitoto Island, erupting 2.3 km of lava. The Pacific Ring of Fire is completed in
Fire ring fireplace may be better used instead. These are designed to contain the entire fire instead of just keeping it in one place. A fire ring may be nothing more than a short, wide section of metal tube, partially buried in the ground. Slightly more advanced fire rings may be partially covered with metal bars so that the fire may be used for cooking. These types are seen at many campgrounds. Fire rings in urban areas, such as on beaches, may be made of poured concrete. Makeshift fire rings can be constructed out of a ring of stones where pre-constructed rings
