Satellite-based eruption warning/prediction system

§1 Prediction and prediction of signs of volcanic eruptions
1. [Precursor phenomenon of eruption]
(1) In general, volcanic eruptions are accompanied by precursors. The general process of a volcanic eruption is that magma at the foot of a volcano accumulates in a magma chamber 1 to 10 km underground, then rises from there and moves to the surface. This accumulation and movement of magma is the source of eruption precursor phenomena.
(2) Volcanic earthquakes, which are precursors of the first eruption, occur when magma breaks and intrudes into the bedrock. If the epicenter gradually becomes shallower, it is thought that the eruption time is approaching. If there is a place where the epicenter is concentrated, the probability that an eruption can occur there is considerably high. Many volcanic eruptions are seen months to hours before the eruption.
(3) Volcanic tremors, which are precursors of the second eruption, are low-frequency vibrations with a longer vibration period than volcanic earthquakes. In addition, the duration of vibration is long, and it has the characteristics of continuous vibration. Volcanic tremors are thought to be caused by pressure build-up in magma chambers and movement of magma.
(4) The third prelude to eruptions, “changes in topography,” occurs when magma rises to shallow depths as the volcanic edifice suddenly rises, slopes steeply, and cracks in the ground. If there is a significant change in topography, an eruption is likely to occur there.
(5) Other premonitory phenomena of eruption include the following.
(1) Electromagnetic anomalies: Earth currents, geomagnetism, abnormal changes in underground electrical resistance, etc.
(2) Abnormal phenomena of heat: Abnormal rise in groundwater temperature, etc.
(3) Abnormal phenomenon of volcanic gas (volcanic plume): Abnormal changes in the composition and emission amount of volcanic gas, emission temperature, etc.

 

2. [Current status and issues]

[1] Current status of prediction of volcanic eruption
Current signs and predictions of volcanic eruptions refer to predicting signs such as the timing, place, and style of eruptions in advance to some extent in order to mitigate disasters caused by volcanic eruptions. By accumulating precursor data of past volcanic eruptions, an observation system using various high-precision observation devices such as seismometers, inclinometers, and extensometers was developed. can be predicted to some extent.

[2] Prediction and prediction of volcanic eruption signs: Current status and issues
(1) In order to evacuate and prevent disasters and prevent damage from becoming more serious, it is necessary to ensure that sufficient time is required from the time the occurrence of precursory phenomena and the issuance of an eruption warning to the actual eruption, which serves as the basis for “prediction and prediction of signs of volcanic eruptions.” Securing a grace period for evacuation is an issue (difficulty in issuing warning timing). There is a problem (first problem) that it is more difficult to foresee and forecast volcanic eruption signs and issue early eruption warnings for "insignificant eruptions" such as steam explosions that do not involve eruption precursors or magma ejections.
(2) Issues in prediction and prediction of signs of volcanic eruptions for "significant eruptions" as well, such as the need for greater precision and accuracy with respect to eruption patterns and transitions in eruptive activity, as well as the need for early and optimized warnings (Part 2 problem).
(3) Many cases of volcanic eruptions are accompanied by precursors that have a clear causal relationship with the eruption. However, it is difficult to predict (1) the start of an eruption, (2) how the activity will change after that, (3) whether another large eruption can occur (difficulty in activity transition), and (4) when it will end. There is also a problem that prediction is difficult (difficulty in predicting the end of the crisis). On the other hand, there is a problem (the third problem) that the causal relationship between earthquakes and phenomena that are considered precursors is not clear.
(4) The “declaration of the end” of volcanic eruptions cannot be made with a carefree judgment and overlooked the danger that will cause casualties. often continue. Since an eruption lasts for a few days at the shortest and several years at the longest, in some cases the warning will be continued for several years (difficulty in the warning period). The social and economic impact of the evacuation of residents and traffic restrictions will also last for a long time, and this is a major issue (fourth issue) in tourist areas near volcanoes.
(5) In addition, even if an increase in activity is confirmed due to precursory phenomena of an eruption, and even if an alarm is issued, an eruption does not occur and the activity continues to decline, often resulting in a "failure" (Problem 5). ).

[3] Current status of volcanic eruption monitoring system
Currently, government agencies, universities, and researchers in municipalities, prefectures, and municipalities with volcanoes are using human-wave tactics to install various types of seismometers, inclinometers, and extensometers scattered (fixed-point installations) in volcano warning areas. Eruptions are monitored through instrumental observations using high-precision observation equipment and field observations by humans. In Japan, there are about 30 active volcanoes that are judged to require special attention, and the Japan Meteorological Agency, universities and other research institutes have established observatories and are constantly observing them. These volcano observation areas are covered by observations of upheaval and ground temperature by GPS installed scattered, as well as regular seismic observations, but the density and number of observations made by the observation equipment is completely insufficient, and the accuracy of the observation equipment is insufficient.・There is a problem that accuracy and speed are lacking. In addition, even if an anomaly is detected, there is a problem that there is no other way but to take a slow response such as dispatching an observation team to the installation location of the observation device that detected the anomaly (problem 6).

Remarks: Infrared spectroscopy
1. 【Overview】
1. Infrared spectroscopy (abbreviated as IR) When a molecule is irradiated with light in the infrared region of 0.8 to 1000 μm, if the vibration period of the infrared rays and the vibration period of the atoms match, individual atoms and atomic groups It absorbs energy according to the period, and the vibration changes from the ground state to the excited state. This absorption appears as absorption in the infrared spectrum. A method of obtaining knowledge about molecular structures by analyzing absorption spectra, since atoms have unique vibrations according to their molecular structures. The most commonly used is the mid-infrared region (2.5-25 μm), where absorption spectra are vibrational spectra caused by vibrations involving changes in the dipole moment among other molecular vibrations. It is used to know the molecular structure and state of the object.
2. When a substance is irradiated with infrared rays, the molecules that make up the substance absorb the energy of the light, and the state of quantized vibration or rotation changes. Therefore, the infrared rays transmitted through (or reflected by) a certain substance are weaker than the irradiated infrared rays by the energy used for the state transition of the molecular motion. By detecting this difference, the energy absorbed by the molecule, in other words, the energy required to excite the vibration and rotation of the target molecule can be obtained.
3. The energy required to excite the vibration and rotation of a molecule varies depending on the chemical structure of the molecule. Therefore, the infrared absorption spectrum obtained by plotting the wave number of the irradiated infrared rays on the horizontal axis and the absorbance on the vertical axis shows a shape unique to the molecule. This makes it possible to know what kind of structure a target substance has, and is often used to determine the structure of organic compounds in particular. In the spectrum, the portion with a wavenumber of 1500 cm-1 or more is called the diagnostic region, and the other portion is called the fingerprint region. The former results from vibrational excitation of single bonds, while the former binds double bonds, triple bonds and hydrogen atoms. Also, even for the same molecule, the infrared spectrum changes slightly depending on the temperature and surrounding conditions (whether it is moving freely, whether it is adsorbed on a surface, etc.). From this, it is possible to know the surface structure of the substance.
2. [Method]
Infrared spectroscopy includes (1) thermal infrared spectroscopy (TIR), (2) near-infrared spectroscopy (NIRS), and (3) FTIR (Fourier transform infrared spectroscopy). There are methods such as
1. Thermal infrared spectroscopy (TIR)
TIR is a type of infrared spectroscopy that is widely used to determine the composition of matter. The constituent materials can be determined by measuring the thermal infrared radiation emitted from the entire object or surface, analyzing its electromagnetic spectrum, and comparing it to the spectra of known materials.
2. near-infrared spectroscopy (NIRS)
NIRS is a spectroscopic method in the near-infrared region. Equipped with a near-infrared diffuse reflectance spectrum analysis function that irradiates the measurement target with near-infrared rays and calculates the components from changes in absorbance. As a feature, absorption of near-infrared rays is extremely small compared to mid-infrared rays and far-infrared rays, so non-destructive and non-contact measurement can be performed without preparing sections.
Difficulties for practical use include the observation of overtones and triple overtones with near-infrared spectroscopy, and the difficulty of direct association with components due to the combination of various factors in light absorption. there were. However, due to the low cost of computers and the development of multivariate analysis (chemometrics), it has become possible to apply it to quantitative analysis.
3. FTIR (Fourier Transform Infrared Spectroscopy) 
FTIR is IR (infrared spectroscopy) in which the FTIR principle is applied (signals are recorded in the time domain and then Fourier transformed into the frequency domain). FTIR does not irradiate the sample with infrared rays of varying wavelengths, but rather irradiates the sample with continuous light and Fourier transforms the interference pattern to acquire an absorption spectrum corresponding to the molecular structure, and to identify the atomic groups ( method of obtaining information on The ability to simultaneously measure incident light over the entire wavenumber range of continuous light enables high-sensitivity measurements in a short period of time.
FTIR has transmission reflection method and measurement method. Permeation methods include the KBr tablet method, the Nujol method, the KBr plate method, the thin film method, the liquid film method, the solution method, and the gas measurement method. Reflection methods include the ATR method, the diffuse reflection method, the regular reflection method (regular reflection light), the regular reflection method (transmission reflection light), the high sensitivity reflection (RAS) method, and the like.
