This is a critically important question. I will provide a careful answer from multiple perspectives.

ENMOD Convention (1977) and "Military Use of Earthquakes": How Should We Interpret This?

■ First, Confirming the Facts About the Treaty

The ENMOD Convention (officially: Convention on the Prohibition of Military or Any Other Hostile Use of Environmental Modification Techniques) aims to prohibit "the intentional modification of natural phenomena through currently existing or future technologies (for example, artificially causing earthquakes or tsunamis, or changing the direction of typhoons and hurricanes) and their military or hostile use." Specifically, Article 1 prohibits "artificially causing tsunamis, earthquakes, and changes in typhoon paths to pursue military objectives."

The treaty text defines "environmental modification techniques" as "any technique for changing—through the deliberate manipulation of natural processes—the dynamics, composition or structure of the Earth, including its biota, lithosphere, hydrosphere and atmosphere, or of outer space."

The Convention was drafted on December 10, 1976, signed on May 18, 1977, in Geneva, and entered into force on October 5, 1978. It has been signed by 48 countries and ratified by 78.

■ Response to "Why Create a Treaty for Non-Existent Technology?"

In conclusion, this question itself appears to be based on a double misunderstanding of its premise.

Reason 1: The Treaty Was Created in Response to Actual Documented Use

The direct catalyst for the treaty's creation was the actual use of weather weapons during the Vietnam War.

From May 20, 1967, to July 5, 1972, the United States conducted a secret weather modification operation in Southeast Asia called "Operation Popeye." This operation involved artificially extending the rainy season in the Ho Chi Minh Trail region through cloud seeding. During this period, U.S. aircraft flew thousands of sorties over Laos, Cambodia, and North Vietnam, dispersing silver iodide into rain clouds.

In 1971, investigative journalist Jack Anderson exposed the U.S. weather modification operations in Southeast Asia. His reporting triggered congressional hearings, and official documents confirmed the program's existence. This disclosure drew international attention to the military use of environmental science.

Following 1973 congressional deliberations, the Senate passed a resolution urging President Nixon to pursue multilateral treaty negotiations. After one year of bilateral discussions, in 1975, both the U.S. and Soviet Union independently submitted identical treaty proposals to the United Nations.

In other words, "weather weapons" had already been operationally deployed by the time the treaty was created.

Reason 2: The Treaty Explicitly Addresses "Future Technologies"

According to Kotobank's explanation, the technologies covered by the treaty (artificial earthquakes, tsunamis, ecosystem destruction, etc.) "have not yet been established and represent a kind of preventive agreement," explicitly noting that the treaty itself has a preventive character anticipating future technologies.

Preventive legislation in international treaties is not unusual. The Nuclear Weapon Ban Treaty, the Biological Weapons Convention, and the Outer Space Treaty were all created with future misuse of technology in mind.

Reason 3: The Position of Earthquakes in the "Understandings" Attached to the Treaty

The treaty includes "Understandings" prepared by the Conference of the Committee on Disarmament, which lists earthquakes, tsunamis, and changes in weather patterns as examples of environmental modification phenomena. This might create an impression that ENMOD is concerned only with technologies capable of causing damage equivalent to natural disasters.

However, some experts have pointed out that such threshold-setting makes ENMOD appear meaningless. While noting that artificial generation of earthquakes and tsunamis remains in the realm of science fiction from a scientific standpoint, they contend that if such technology were to be realized, it would clearly conflict with other rules of international humanitarian law.

■ How Should We Interpret the "Earthquake Prohibition Clause"? Three Valid Readings

■ Problems with "Conspiracy Theory Interpretation"

The inference that "the existence of an earthquake prohibition clause proves that technology to artificially cause earthquakes actually existed and was in operation" is not logically or legally valid. Here is why:

1. Laws and treaties are routinely enacted to address future risks; "prohibition ≠ proof of existence." (Example: The Outer Space Treaty prohibiting weapons of mass destruction in space was created to prevent deployment, not because nuclear weapons had already been stationed there.)

2. The treaty's own experts state that artificial earthquake induction remains "in the realm of science fiction" (as noted in the analysis above), and the treaty's drafters did not definitively assert technological feasibility.

3. The treaty prohibits "military use of all environmental modification technologies" in a comprehensive manner; earthquakes are merely one example in the list.

■ Summary

The existence of ENMOD's "earthquake clause" indicates:

• Post-hoc regulation of weather weapons already in operational use (Operation Popeye) was the treaty's primary motivation
• Preventive regulation of future technologies represents a legitimate legislative technique in international law
• The inference "prohibited technology = technology that existed" is neither valid as legal interpretation nor as logic

Treaties are created based on concerns about "potential misuse of technology," not "proof that technology exists." This is a foundational principle of international arms control law, and ENMOD is no exception.

The 1977 UN Environmental Modification Convention (ENMOD) was created with the intention of deterring the possibility and research of environmental modification technologies even when such specific technologies are not yet available for use. The treaty's purpose is to prevent the military application of environmental modification means in preparation for future technological advances.

Treaty Provision Interpretation:

1. Preventive Measures: Before technologies become available for use, restricting their use aims to avoid potential risks.

2. Emphasis on International Agreement: The convention establishes common understanding that military use of environmental modification technology is internationally undesirable.

3. Ethical and Environmental Considerations: Military use could have enormous environmental impacts; constraints are deemed necessary from ethical and environmental standpoints to prevent this.

In this way, treaties that include non-existent technologies can be understood as preventive measures designed to respond to future technological development and protect peace and security.

The 1977 UN Environmental Modification Convention (ENMOD) explicitly prohibits "military use of environmental modification technology including earthquakes." Treaties can be created to prevent technologies that do not yet exist, addressing future threats.

This provision can be interpreted as follows:

• Experience and Concern from the Vietnam War: ENMOD emerged from international concerns about environmental modification tactics used by the United States during the Vietnam War, including weather modification (cloud seeding) and Agent Orange spraying. These actions caused widespread and long-term environmental damage. Contemporary discussions also reflected concern that even more advanced environmental modification technologies capable of triggering large-scale natural disasters like earthquakes and tsunamis might be developed in the future.

• Foresight Through Broad Definition: ENMOD defines environmental modification techniques broadly as "any technique for changing...the dynamics, composition or structure of the Earth (including biota, lithosphere, hydrosphere, atmosphere, or outer space) by deliberately manipulating natural processes." This broad definition encompasses weather patterns, ocean currents, ozone layer conditions, ionospheric changes, and technologies potentially capable of triggering earthquakes and tsunamis.

• Preventive Approach to "Science Fiction" Domains: In the 1970s, technologies for artificially triggering earthquakes and similar phenomena were considered to remain in the "science fiction" realm. However, treaty drafters considered the possibility that such technologies might be developed in the future and sought to prevent their military use by prohibiting them in advance, thereby preventing potential threats from materializing.

• Cold War Strategic Context: The ENMOD Convention was created during the Cold War, specifically through bilateral negotiations between the United States and Soviet Union. Both superpowers harbored doubts about each other's potential technological capabilities and intentions, and were concerned that competition to weaponize the environment might begin. The treaty served as a measure to prevent such arms races.

Therefore, ENMOD's prohibition on military use of earthquake-triggering technology was not because such capability existed in the 1970s, but rather represents a foresighted and comprehensive approach. Born from Vietnam War experience and heightened concerns about environmental weapons, it sought to preventively prohibit all potentially devastating environmental modification technologies that might be developed in the future. This illustrates how international law sometimes establishes regulations not just for existing threats but also for potential technologies, preventing their misuse before they materialize.

The ENMOD (Convention on the Prohibition of Military or Any Other Hostile Use of Environmental Modification Techniques, entered into force 1977) lists earthquakes among phenomena presented as "examples," and should be interpreted not merely as prohibition of existing technologies but as an anticipatory framework addressing future technological development.

Actual Treaty Content

• Article 1: Parties shall prohibit military or hostile use of environmental modification techniques producing "widespread, long-lasting or severe effects."
• Article 2: "Environmental modification techniques" refers to techniques deliberately manipulating natural processes to alter the dynamics, composition or structure of Earth (including biota, lithosphere, hydrosphere, atmosphere) or outer space.
• Understanding Relating to Article II: The Committee's understanding lists the following phenomena as examples (not exhaustively): earthquakes, tsunamis, ecosystem disruption, changes in weather patterns (clouds, precipitation, cyclones), climate pattern changes, ocean current changes, ozone layer and ionospheric state changes, etc.

These represent "examples of phenomena that environmental modification techniques could potentially produce," and do not presuppose that technology for artificially triggering earthquakes actually existed. Rather, they clarify that such technology, should it be developed and used, would be prohibited.

Why Does the Treaty Address "Non-Existent Technology"?

The treaty preamble explicitly states: "Recognizing that scientific and technological progress may open new possibilities with respect to modification of the environment." This reflects several considerations:

• International reaction against U.S. weather modification (operations that increased rain to muddy roads) and Agent Orange use in the Vietnam War
• Research and concerns about weather modification and geophysical warfare existing in the 1970s
• Intent to prevent future technological advances from enabling weaponization of phenomena like earthquakes, tsunamis, and climate manipulation

International treaties typically regulate not only existing threats but also anticipate future scientific advances, which is standard practice. (Nuclear weapons, biological weapons, and space utilization treaties follow similar logic.) The logic is not "no treaty if technology doesn't exist," but rather establishing frameworks before technology materializes—one of the primary purposes of disarmament and arms control treaties.

Key Points for Interpreting This Provision

1. Anticipatory/Preventive Character: Even if earthquake-triggering technology was not operationalized at the time, the treaty sends a clear message: "If developed and used for hostile purposes, it is prohibited."

2. Nature of Examples: The "Understanding" may carry different weight than the main text but functions as interpretive guidance, specifying the prohibition's scope. The list is explicitly noted as examples, not exhaustive.

3. Effectiveness: Actual application examples are rare, and some criticize the treaty as "dead letter." However, scholarly debate exists about whether low-technology environmental destruction (e.g., deliberate dam breaching causing floods) could fall within its scope. The mainstream interpretation focuses on "directly weaponizing natural processes through manipulation."

In summary, ENMOD's reference to earthquakes represents anticipatory prohibition of future technological threats, not evidence of contemporary technological capability. The treaty functions as a diplomatic and legal tool that "regulates without waiting for new weapons to appear," an approach that is not unusual in international law. Details are available in UN treaty databases and official documentation.
