# 1. Introduction

1500 volcanoes on the Earth are potentially active (see figure 1). One third of them have been active during this century. At the beginning of the third millenium, 10% of the world population is living in areas directly threatened by these potentially active volcanoes.

<figure><img src="image_3.png" /><figcaption>**Figure 1 : Map of the potentially active volcanoes.**</figcaption></figure>

The aim of this work is to provide the control simulator of the Pleiades mission (C.N.E.S.) with data on volcanic risks. The simulation is made on the basis of the real activities of the world volcanoes in the period 1999-2001.

# 2. Volcanoes to be monitored

The list of the volcanoes to be monitored by the system in priority has been established using the archive from the Smithsonian Institute (web adress). For active volcanoes, we mean volcanoes in eruption between january 1999 and june 2001. Moreover, for the same period, we can add about forty inactive volcanoes, whose localization and forewarnings of activity make them highly dangerous for the neighbouring population. This represents a totality of 115 volcanoes (see figures 2 and 3 and tables 1 and 2). For the simulation, we have used the data relative to the year 2000.

**3. Risks related to volcanic eruptions**

The risks associated with volcanic eruptions depend at first order on the effusive or explosive nature of the volcano.

Effusive volcanoes generally do not represent any vital risk for the population. Their activity is characterised by lava flows. The velocity of a lava flow, less than one km per hour in common cases, allows people evacuation in general. There are exceptions like the Nyiragongo area (where lava flows reached several tens of km per hour in 1977), or Hawaï or Piton de la Fournaise where lava flows can be very fast close to the vents and thus mean a risk for visitors and in some cases the inhabitants of the villages.
However, they can cause important damages to the goods or to the economy. The area covered by a lava flow is typically about ten kilometres over a few hundred of meters width. According to the volcanoes type, the eruption duration differs from a few weeks for the Mont Etna (Sicilia) or the Piton de la Fournaise (Réunion Island) to a quasi-permanent activity for the Kilauea (Hawaiï). Seismic activity and deformations at centimetre level of the edifice could occur a few weeks before the eruption.

Because of the violence and extent of the eruptions, explosive volcanoes create a more important risk the population. They represent 90% of the active volcanoes. Their activity is sometimes characterised by domes growth (diameter of several hundreds of meters, growing at about 2 meters per day) and also by collapses sequences which may cause pyroclastic flows and landslides. The velocity of the propagation of a pyroclastic flow (which is a mixing of gas and rocks at high temperature) can by far exceed 100 km per hour over distances of about ten kilometres. The collapse of a caldeira (like Santorini in Greece or Krakatau in Indonesia) or the collapse of a flank (like Saint Helens Mont in 1980 at the USA) cause partial or total destructions at a regional scale. Nevertheless, their frequency is smaller (one or two events per century).

Other common risks exist between these two types of volcanism:

- Ash columns: they can reach 30 km in altitude. They represent a major hazard for the air traffic. This kind of activity is actually monitored by meteorological satellites. When they are thick, the deposits of such columns can trigger roof collapses of buildings.

- Lahars: mixing of volcanic deposits and water (due to the melting of a glacier or due to precipitations of recent deposits). These mud flows could cause, several months after the eruptions, important disasters over a distance of hundreds of kilometres.

## 4. Foot print to be monitored

For most of the volcanoes, the active zone covers an area of about 5 km x 5 km, centred on the summit of the volcano. Eruptive faults, domes and precursor signs of activity are concentrated in this zone. A larger area (10 km x 10 km) includes almost all the volcanic deposits. This area could be offset and extended depending on the presence or not of habitations near the volcano. The proposed area for SVO concerns a foot print of 6 km x 6 km.

## 5. Atmospheric conditions

The quality of images is not only constrained by atmospheric conditions (snow, clouds...) but also by the presence before, during and after eruptions, of ash and gas columns. These returns reduce the frequency of the observations in visible domain.

The cloud coverage must be less than 10 % for the images used for the creation of a D.E.M. (Digital Elevation Model) and less than 25 % for the monitoring. But, it should be highlighted, that for a dome growing, the local presence of clouds is much more decisive than the rate of clouds for the whole image.
## 6. Frequency of the eruptions

During the year 2000, according to the accurate knowing and dangerousness of each volcano, 77 volcanoes are counted as active - even if it is not really the fact - in order to establish a table with the best expected acquisition frequency. A few number of volcanoes show activity signals. Among them, one or two are located near inhabited areas. The difference between active volcanoes and volcanoes with precursor activity signals can be due essentially to the lack of available data for volcanoes situated in uninhabited zones or without permanent tools of observation. In fact, with respect to the earthquakes, volcanoes begin their eruption producing precursor signals which are studied by actual monitoring tools.

## 7. Expected specifications of the images

The expected resolution for the visible images is 1 meter or best in panchromatic and multispectral modes. Such a resolution allows the monitoring of a lava dome growing.

We estimate that the most favourable hour for the acquisition is 10 A.M. (local time) because images have to show lighting conditions as more constant as possible.

## 8. Simulation of the types of requests

The frequency of observations for a volcano depends on two parameters: its activity and the proximity of population. The volcanic activity can be split in several phases:

- Inactive phase: the acquisition is limited to stereoscopic shot for the creation or actualisation of a D.E. M.

- Alert: once precursor signals of an imminent eruption are detected by volcanological observatories or by seismological stations, an accentuated monitoring of the volcano is needed in order to study the future eruption as best as possible.

- Eruption: regular monitoring of the area with a frequency depending on the type and localization of the volcano.

For the simulation, 8 cases have been taken into account according to two criteria: the activity type and the density of population. The 8 cases are described with the figure 4. In addition to these 8 cases, the creation of a complete data set has to be added, that is to say 2 images in stereoscopic conditions per volcano for a year. This data base will be a reference tool for the study of the deformations of the edifice during eruptions. The percentage of cloud coverage is required at 0 % because this base could be realised over a year.

The priorities of the acquisitions will be set according to the two criteria over a scale from 0 to 5 (0 means the highest priority).

Comment: although the creation of the data base covers several years, only forty inactive volcanoes will be selected for the simulated year.

Images will be required in stereoscopic conditions, except the request at level 0 (higher priority, eruptive volcanoes with high or mean density of population). In these areas, we privilege the access to a big number of images in order to study the risks as soon as possible.

The total number of requests for the simulated year is 3266 for 115 monitored volcanoes.
This selection includes 77 active volcanoes.
