Mauna Loa's last eruption occurred from March 24 to April 15, 1984.
Mount St. Helens is in Skamania County of Washington. The stravolcano first eruption was a phreatic eruption on April 6, 1980 that was developed to magma before May 18, 1980.
The answer depends on what you want to use it for, and the nature of the eruption the first time. Some eruptions result in the destruction of the model or most of it. Consider Mt St Helens, for example.
Normally this would be near the surface. However other factors can come into play such as re-use of materials from other sites and from earlier times. This is frequently known to occur. In this case there is a need for knowledge which enables cross-referencing with other discoveries. It probably also depends on the amount of disturbance of the site, where older layers may cover more recent, but normally the oldest is on the bottom with the most recent near the top.
Mount Pelee in Martinique is estimated to be over 100,000 years old. It is a stratovolcano that has been active for thousands of years, with its most famous eruption occurring in 1902.
Mission San Gabriel Arcángel had to be rebuilt due to damage from various earthquakes over the years, with the most recent significant damage occurring in the 1994 Northridge earthquake. The structural integrity of the mission was compromised, leading to safety concerns and the need for extensive restoration and rebuilding efforts.
The most recent eruption of Mauna Loa was in 1984. There have been several instances of increased seismic activity and ground deformation since then, but no eruptions. Mauna Loa is constantly monitored for any signs of potential eruption.
Mauna Loa, located in Hawaii, has had 33 recorded eruptions since its first well-documented eruption in 1843. Its most recent eruption occurred from November 27 to December 10, 2022. Eruptions at Mauna Loa can vary in frequency and intensity, contributing to its status as one of the most active volcanoes in the world.
Mauna Loa's most famous eruption was in 1984, when it erupted for 22 days from March 25 to April 15. This eruption was significant because it was one of the largest eruptions in recent history and caused widespread concern due to its potential impact on nearby communities.

most recent and destructive was the eruption that was in 1707-1708
As of my last knowledge update in October 2023, there was no recent eruption of Mauna Kea that required significant rebuilding costs. Mauna Kea is primarily a dormant volcano, and its last major eruption occurred around 4,000 years ago. If there have been new developments or eruptions since then, I recommend checking the latest news sources for the most current information on any related costs.
Mauna Loa's most recent eruption occured from March 24, 1984 to April 15, 1984. Eruptions in 1926 and 1950 destroyed villages, Mauna Loa has been intesively monitored by the Hawaiian Volcano Observatory since 1912. The first historical eruption occurred in 1832 and since then 32 eruptions have been documented. The most prominent historic eruptions of Mauna Loa with extensive lava flows were in 1855, 1881, 1887, 1907, 1916, 1919, 1926, 1935, 1942, 1950 and 1959.
Mauna Kea's latest eruption occurred from 1983 to 1996, lasting a total of 13 years. This eruption was characterized by intermittent activity, with periods of both intense lava flow and relative quiet. It primarily produced lava flows on the mountain's northeastern rift zone, significantly altering the landscape. Subsequent eruptions have been rare, with the most recent volcanic activity on Mauna Kea being limited to its historical record.
Mauna Kea has erupted at least three times in the past 10,000 years. The most recent known eruption occurred about 4,600 years ago. However, Mauna Kea is considered dormant, not extinct, meaning it could potentially erupt again in the future.
The most recent eruption of Kilauea began on December 20, 2020.
Mauna Loa is an active shield volcano in Hawaii that has erupted numerous times in the past, causing damage to the surrounding areas. Its lava flows have destroyed homes, roads, and vegetation, and posed a risk to local communities. The most recent eruption was in 1984.
