Earthquake Catastrophe Risk

Earthquake Catastrophe Risk Map
U.S. FEMA Map

The United States Geological Survey published a map showing the earthquake catastrophe risk in different parts of the country. This data comes from seismic records of 130,000 earthquakes of a magnitude on the Modified Mercalli intensity scale of six or higher, which is severe enough to frighten people, move furniture, and cause other damage, like falling plaster. Most of us know about some geologically unstable regions of the country, but other areas may be surprising.

The highest earthquake catastrophe risk within the next 100 years is essentially the whole western edge of California, the southern part of Alaska from Juneau through the Aleutians, and the eastern islands of Hawaii. Those areas with a 75 to 95% chance of a damaging earthquake include virtually all of California, the Yellowstone National Park area, and the intersection of Missouri, Arkansas, Tennessee, and Kentucky. The study says that 230 million people live in areas with a 95% chance of a damaging earthquake.

The point of this data is that there will be a massive earthquake sometime in the next 100 years, causing death and structural damage. Many people will blame this coming catastrophe on God. The fact is that earthquakes are a natural product of the uplift of the land. Without those forces, erosion would have brought all land masses to sea level. Despite the data, humans continue to build huge structures in areas where earthquake catastrophe risk is high. This can be added to a long list of situations where humans set themselves up for a catastrophe.

My wife and I were on Hawaii’s “Big Island” when Kilauea erupted in May 2018. In one of the places we visited, lava flow had destroyed many homes. We happened across a man who was working on a new house. I asked him if he was not concerned that another lava flow might destroy this house. He laughed and said, “God wouldn’t do that to me twice.”

We need to understand that God does not cause bad things to happen to us. If you eliminate what humans do to each other and the foolish acts humans engage in (like building a house in the path of a lava flow or on an earthquake faultline), much human pain and suffering would stop. Read James 1:13-17.

Tectonic Plates and Continental Drift

Tectonic Plates and Continental Drift

One of the interesting designs of planet Earth is the fluid nature of the crust and interior of the planet. Looking at a global map suggests that North and South America must have been connected to Europe and Africa in the past. As technology has improved, we have been able to see the connections and identify and measure the slowly moving tectonic plates and continental drift. This movement gives rise to surface features that affect human life and bring resources to supply the needs of all living things.

In 2005, geologists tracked 163 earthquakes as a 35-mile-long chasm opened in Ethiopia’s Afar Desert, where a volcanic eruption occurred. In 2018, a giant fissure 50 feet deep and 65 feet wide opened west of Nairobi, Kenya. These changes are surface expressions of movement in the mantle of magma inside the planet. The movement of tectonic plates happens very slowly, but even at a rate of less than an inch a year, scientists can measure it.

Tectonic plates and continental drift formed the Red Sea and the Gulf of Aden. Along the edges of the various plates, material from the surface sinks back into Earth’s interior, while volcanos bring new materials to the surface, creating a colossal recycling system. Planet Earth is active, continuously producing new land with fresh minerals.

Because this process is so slow, its impact on human existence is minimal. However, people continue to build large cities along the fault lines. In California, we have the making of a colossal disaster as cities like Los Angeles straddle a geologically active region. The warnings are there, but they go unheeded.

Understanding the design of our planet with tectonic plates and continental drift should enable us to avoid geologic catastrophes and locate the mineral resources we need. Proverbs 8:22-26 finds “Wisdom” speaking about her presence at the beginning of God’s creation work. We see God’s wisdom and patience as we look at our planet’s design.

Does God Cause Natural Disasters?

Does God Cause Natural Disasters?One of the struggles we all have is understanding why God allows disastrous events that cause massive destruction and suffering to humans. Atheists use this question as a club against faith, and it is perhaps their best weapon. The list of events that harm humans is huge – earthquakes, tornadoes, tsunamis, landslides, fires, floods, droughts, etc. At this time of the year, hurricanes are at the front of our awareness. Does God cause natural disasters to punish people?

If you have just seen a natural event take place that destroyed your home and killed a loved one, no rational explanation is going to be of any help. Our hearts go out to those of you who are trying to make sense of what seems to be a senseless disaster that has hurt them in ways that no one else can understand. We don’t want anyone to think that we have all the answers. If somehow we can remove ourselves from our own emotions, here are three things we need to understanding:

1) God does not cause disasters. The notion that God brings catastrophes upon people He doesn’t like, or people who violate His laws or commands is inconsistent with the nature of God. James 1:13 tells us clearly that God doesn’t tempt us in any way. The passage specifically deals with moral temptation, but verse 17 goes on to say that “every good gift and every perfect gift is from above and comes down from the Father of lights with whom there is no variableness, neither shadow of turning.” God brings good things. Jealousy or vindictiveness is not a part of His nature.

2) Human stupidity in the face of natural processes is a significant cause of calamity. Hurricanes are a classic example of this. The Earth has zones of climate that are made functional by natural processes which create climate zones. The Hadley Cell explains these zones, with different zones creating tropical rainforests and deserts. Those zones are balanced by natural processes such as hurricanes that carry water into what would otherwise be a desert. Thirty-degree latitudes north and south would be deserts if it were not for hurricanes that bring massive amounts of water to recharge water supplies. In the United States, northern Florida and southern Georgia would be deserts with no water were it not for hurricanes. Humans ignoring this system and building in areas known to be vulnerable to hurricanes while removing natural barriers such as mangroves causes much of the suffering and death.

3) Human mismanagement of God’s creation due to greed and ignorance is a major cause of human suffering. Genesis 2:15 tells us that God gave humans the assignment to take care of “the garden, to dress it and keep it.” We are the caretakers of what God has created, but selfishness and greed have caused significant suffering and destruction. We all know that polluting the air, rivers, lakes, and now the ocean has led to cancer and now appears to be affecting Earth’s climate. We all understand that exploitative agriculture has led to fires, erosion, dust storms, and insect swarms. Scientific journals are full of studies showing how human mismanagement of what God has given us is leading and has led to disaster.

Does God cause natural disasters? The answer is “NO!” It isn’t God’s will that humans suffer from natural disasters, but God has never promised us that He will protect us from ourselves. What God has done is to build a base by which His servants can help those who are suffering. The Church has a responsibility to show God’s love and compassion for the hurting. Atheists need to pitch in and help clean up the mess, not try to blame God. (Read Matthew 25:31-40.)

Natural Disaster and God

Natural Disaster and God Every time natural disaster strikes anywhere in the world, people tend to blame God for what happened. The current examples are the hurricane in the panhandle of Florida, and the catastrophic earthquake in Indonesia. What atheists and skeptics fail to realize about natural disasters is that the vast majority of catastrophes are due to human ignorance and mismanagement. Both of the current crises demonstrate that point.

The major loss of life and devastation in Indonesia is in an area that was built on a restored landfill. Gravel, sand, and dirt were brought in to make living space for what were mostly poor workers and laborers. Engineers have warned for a very long time that the land under the highly populated area was unstable, and the earthquake was enough to cause that land to move in a significant way. You could call this a human-designed natural disaster.

In America, we have the same situation in New Orleans and Los Angeles. New Orleans is built on an area that is soft and prone to flooding, and part of the city is even below sea level. Los Angeles is built in an earthquake active area riddled with faults. It isn’t a question of whether a severe earthquake will happen in the Los Angeles area, it is just a question of when. There will be a catastrophe when that happens, and God will be blamed for causing it.

Hurricane Michael is a demonstration of another human-caused natural disaster. One of the designs of our planet is the method which brings water to areas that would otherwise be a desert. At the equator, the direct sunlight evaporates ocean water which falls as rain causing tropical rain forests. The remaining dry air moves north or south in what is called the “Hadley Cells.” When that dry air cools and returns Earth’s surface at 30 degrees latitude, it produces desert conditions. Most of the world’s great deserts are found at 30 degrees north or south latitude–the Sahara, the Australian Outback, the Mohave, etc.

In the southeastern United States, 30 degrees north latitude runs through northern Florida. That area would be a desert were it not for hurricanes. The heating of the ocean in the summer is sufficient to lift massive amounts of water which are then carried to the land restoring lakes, rivers, and underground aquifers. Without that large water supply system, that area would be a desert like the Sahara. The land area around the Gulf of Mexico in its pristine state had barrier beaches and mangrove forests that moderated the wind and storm surge. When I was a child living in Alabama, we looked forward to “hurricane parties” when we would “button down” and enjoy not having to work. The storm’s damage was limited, and even the storm surge was never a problem. That was 80 years ago.

Since that time, we have modified the shoreline stripping the barrier beaches of vegetation, and building houses where they are easily destroyed by water or wind. Even the vast mangrove swamps that were a buffer to storms have been removed, and channels have been built lined with aluminum houses, golf courses, and boat facilities. It was an invitation for a natural disaster.

We are sympathetic to those who have suffered because of the greed and foolishness of city planners and real estate salespeople. But don’t blame God for the foolishness of human actions.

Volcán de Fuego – Volcano of Fire

Volcán de Fuego
Volcán de Fuego is Spanish for Volcano of Fire, a volcanic mountain in Guatemala. It has been active on-and-off for years. On Sunday, June 3, 2018, it erupted with fury. It had previously flared up in January and February, but this was the worst so far this year. Volcán de Fuego is famous for spewing out smoke daily and being continuously active at a low level. This time it erupted violently resulting in many deaths. Molten lava, flying rocks, hot gasses including sulfur dioxide threaten homes and lives in the area. The pyroclastic flow travels at speeds up to 50 miles (80 km) per hour or more. The gas rose 5 miles (8 km) into the troposphere. The map shows the area where the wind has taken the dangerous sulfur dioxide. The photo is of a previous eruption.Volcano Fuego Eruption June 2018

At the same time of the eruption of Volcán de Fuego on the big island of Hawaii, Mount Kilauea is still erupting and creating massive destruction, but with no fatalities so far. The question is, “Why do we have volcanos?” Perhaps we should ask, “Why do we need volcanos?”

The answer to the first question has to do with the composition and structure of Earth. The crust of the Earth, along with the upper mantle below it, is divided into sections called tectonic plates. Volcanos (and earthquakes) often occur near the boundaries of those plates. The movement and repositioning of those plates created the continents we have today. Beneath Earth’s crust, there is hot and partially molten material in an area known as the mantle. Pressure and the decomposition of radioactive material within the core of the Earth cause the elevated temperature. The fact that the minerals are in a molten state because of the extreme heat allows the movement of the tectonic plates on the surface. A volcano is a rupture in Earth’s crust that allows the escape of hot lava and gas from a magma chamber below the surface.

The answer to the second question of why we need volcanos is that they are part of Earth’s recycling system. Erosion of Earth’s surface leaches away nutrients from the soil. Volcano eruptions bring to the surface essential nutrients to nourish the soil allowing plants to grow and making farming more productive. They also bring to the surface valuable minerals that we need for modern, advanced civilization. Volcanos have also created many islands, such as the Aleutian islands and the islands of Hawaii. The movement of tectonic plates and the eruption of volcanos have occurred throughout Earth’s history. Without the movement of the tectonic plates with the resulting earthquakes and volcanos, Earth’s crust would be flat and covered with water. We would not be here.

Although volcanos often cause the destruction of homes, disruption of weather patterns, and loss of life, they also play a vital role in giving us this vibrant, life-supporting planet. They are another evidence of God’s creative power.

Tectonic Plates, Earthquakes, and Volcanos

Tectonic Plates Map
Tectonic Plates Map

Yesterday (April 5, 2018) there was a magnitude 5.3 earthquake off the coast of California near Los Angeles. No serious damage resulted, but scientists say there is a one-in-twenty chance that quake could be the foreshock of a larger quake. This brings up the question of why we have earthquakes. Did God do a poor job of designing the Earth?

The answer to that question is, “No.” Earthquakes result from factors that are essential for life on Earth. Earth’s crust consists of tectonic plates floating on the mantle, which is a region of molten rock. Under the continents, the Earth’s crust averages 18 miles (30 km) thick. Under the oceans, the crust is only about 3 miles (5 km) thick. The mass of the crust puts great pressure on the molten rock in the mantle causing it to be very viscous. If a crack opens in the crust, the molten rock will move upward, become more liquid as it is under less pressure. Then it may burst from the surface creating a volcano.

Volcanoes create mountains, and so does the movement of the tectonic plates. The tectonic plates moving against each other also produce earthquakes. Sometimes the plates will move against each other horizontally. We call that a slip-strike earthquake and that is what happens in the San Andreas fault in California. The quake that just occurred was a thrust quake where one side of a fault thrusts over the top of the one next to it. The Rocky Mountains and the Himalayas were pushed up by movement of the tectonic plates.

By the creation of mountains, the Earth has been continuously renewed. On the surface of the continents, erosion, and weathering break up solid rock to produce sand, clay, and ultimately topsoil. Erosion cuts down the mountains and deposits sediment in the lower elevations. Further erosion carries the sediment out into the oceans. In the deepest parts of the ocean, there are trenches. Huge amounts of sediment settle into those trenches, but they never get full. That’s because the sediment sliding into the trenches is finding its way down into the mantle.

The movement of sediment replenishes the mantle with new material which then resupplies the continents with new rock. Volcanoes erupt bringing recycled minerals and nutrients to the surface. Volcanic soils are the richest soils on Earth. This system has also brought the iron and other essential minerals into the Earth’s crust.

This is a greatly oversimplified explanation of the comprehensive recycling system that God designed into the planet on which we live. Earthquakes and volcanoes are destructive when humans build homes and cities close to the fault lines and active volcano sites. But if the Earth’s recycling system didn’t exist, erosion would eventually reduce the land masses to sea level, and Earth would be a water world.

Doomsday Predictions Misguided

Doomsday Predictions
Just about every day you will see a headline in some periodical saying that the world will soon end in catastrophe. These doomsday predictions come from tabloids and church bulletins and always bring some kind of data to support them. Religious periodicals usually quote from Revelation and tabloids will take something out of context from a scientist or political figure.

The fact is that the major possible causes of global catastrophe do not come from periods of unusual natural activity. Earthquake numbers for the past ten years have been much smaller than 50 years ago. Hurricane frequency and intensity are not higher than in the past, although human mismanagement of shorelines has increased the damage even a small hurricane can produce.

The Sun is not becoming more active. The current cycle of solar activity is the lowest it has been in 100 years. In 1990 solar activity peaked at almost 300 sunspots. In the next maximum which happened in 2000, there were just over 200 sunspots. The last cycle which was in 2014, had 100 sunspots. In the December 2017 issue of Astronomy magazine, the lead article by Bruce Dorminey (page 20) is titled “Why Has the Sun Gone Quiet.” He suggests that the Sun will be relatively quiet for a long time.

In spite of the doomsday predictions, the biggest threat to our survival does not come from the natural world. God has designed a world that is remarkably stable. Earthquakes, hurricanes, and solar activity may cause problems, especially where humans have built vulnerable structures and removed natural safeguards, but our greatest danger is from each other. Our biggest problems come from humans refusing to do what Jesus told us would lead to our safety and security now and in eternally. You can read about it in the “Sermon on the Mount” recorded in Matthew chapters 5-7.
