Hardcore crisis

"Okay, what work is waiting for us today?"

"What kind of work? Brother, you must be sleeping too deeply."

"What do you mean?" Franklin was a little confused.

"Wait, you didn't find anything?"

"What exactly did you find?"

"Well, I underestimated your retardation."

Patting Franklin on the shoulder, Lamar pulled Franklin out and said angrily: "Damn, bastard, ****, our warehouse collapsed, and our goods are all gone..."

When Franklin was pulled out of the door by Rama, he looked at the street outside the house in shock. An unprecedented crack spanned the entire street. Looking to the left, he didn't know where it extended.

The streets were filled with people, and everyone had an uneasy look on their face.

"This is……"

"earthquake."

Rama cursed: "A damn earthquake destroyed our warehouse. All the goods there are gone. Kos will not let us go."

"Earthquake, oh my God."

If Franklin could look down from a height of several hundred meters, he would have discovered that there were more than one cracks on the edge of Los Angeles. A sudden shock shook the entire city, and the sound of fire engines roaring sounded throughout the city. , running towards the place where the fire broke out due to the earthquake.

…

On the rugged country road, during the summer in Iceland, the farm is as lush and peaceful as ever. This beautiful scenery attracts many tourists from all over the world every year. For example, Dr. Main is looking out of the car window at this time. Several tourists were seen holding SLR cameras to take pictures of the beautiful scenery of the farm.

He sighed, looked away from the window, and returned to the tablet in his hand, his eyes full of worry.

After driving along the farm road for about twenty miles, we could see the Katla volcano getting closer and closer in the distance. This major volcano in Iceland is in a state of ice all year round, and it is very different from the green grassland below the mountain. It is in sharp contrast to the forest, and just below this volcano, Dr. Myne's destination is about to arrive.

"Chichi..."

The dilapidated pickup truck came to a sudden stop, almost causing the tablet computer in Dr. Main's hand to fly out.

"Sorry, this car really needs to be retired."

Taking off his hat, the old man smoking a cigar said this without any apology.

"Thank you, Corey."

"You're welcome, old friend. I'm going back first. If you want me to pick you up, just give me a call. Of course, I can't guarantee that I'll be available at any time. You'd better call me in the afternoon."

"I understand, help me say hello to Nan Lin."

After opening the car door and walking down, someone happened to come out of the observation station in the distance. When he saw Dr. Maien, he suddenly said happily: "Dr. Maien, why are you here so soon?"

"Haha, Ryan, we haven't seen each other for a long time."

"Yes, Dr. Main, the last time we met was three years ago."

Walking over to help Dr. Main hold the suitcase, Ryan said, "I thought you wouldn't come until tomorrow. I was also prepared to pick you up tomorrow... Why didn't you call me in advance?"

"I know you are very busy, so I won't bother you. Corey sent me over just as he was free."

Following Ryan towards the observation station, Dr. Myne said as he walked: "When did this anomaly start?"

"About two weeks ago."

Pushing open the door of the observatory, Ryan clapped his hands and said: "Jack, Boss, you two, come here, this is Dr. Maien..."

"Dr. Main, these are my two assistants."

"Hello."

"Hello."

Seeing the two young people's reserved looks, Dr. Main said hello. Perhaps it was his kind expression that made the two young people look much more relaxed.

"Dr. Main, do you need to take a rest first, or..."

"Let's get to the topic as quickly as possible. I'm not tired yet."

"Okay, Dr. Main, please come here."

Taking Dr. Main to the five parallel monitors, Ryan operated the mouse to enter the interface he needed.

"Since two weeks ago, we have monitored a series of thousands of small earthquakes near Katla, most of which are magnitude 1-2 earthquakes, with the source located 7-10 kilometers below the Katla formation..."

On the monitor, the Hengxing radar image that monitors volcanic signals shows that the crust in this area undulates like ocean waves. Although the undulations are not large, only about 1-2 centimeters, in Dr. Maien's eyes, this is undoubtedly the accumulation of underground pressure. clear signs.

Magma from deep within the Earth is moving, and while he can't confirm where it's heading right now, there's no doubt that the pressure must be released somewhere.

On another display screen, the specific time, epicenter location, focal depth, magnitude, epicenter distance and other data of these earthquakes were displayed. Dr. Main glanced at it and moved to another display screen, where there was a record of P , S-wave vertical waveform and spectrum characteristic quantities. These characteristic quantities and dynamic characteristic quantities can be used as short-term forecast indicators.

For normal continental plates, these thousands of earthquakes are really insignificant and very normal. However, if these thousands of small earthquakes occur in a volcanic area, then attention must be paid.

"The last two eruptions of Katla volcano were in 1955 and 1999, right?"

Dr. Main looked back at Ryan.

"Well, yes, neither eruption destroyed the 10 kilometers of ice in the crater."

Ryan nodded.

"But it's less than eight miles from Eyjafjallajökull."

Dr. Main looked solemn.

The last time the Eyjafjallajokull volcano erupted in 2010, the eruption resulted in the cancellation of 100,000 flights in Europe. The spreading volcanic ash floated over the European continent, making the entire sky gloomy and without sunlight. .

The erupting Eyjafjallajökull volcano is just 8 miles east of here, so close at hand.

"Dr. Main, you said a few years ago that the eruption of the Eyjafjallajökull volcano was just the beginning, and that the pressure on the earth's crust had not been fully released?"

"Yes, I don't think Eyjafjallajökull will release all the pressure. I studied all the records from 934 to now. Eyjafjallajökull usually precedes Katla. Several years of eruptions, this guess has been verified five or six times. After that volcanic eruption, I recorded the inclinometer many times and found that the slope of Katla has been changing..."

"I think so too, Dr. Myne..."

"Dong dong dong dong..."

Before Ryan could finish speaking, the whole room began to shake. As geophysicists, the two of them naturally immediately understood what was happening.

earthquake!

And it is at least an earthquake of magnitude 4 or above.

Ryan shouted: "Quick, get out."

There is flat grassland outside, which is definitely safer than hiding in the house.

Without saying anything, Ryan pulled Dr. Main and ran outside. Only a few people ran out of the door before the sudden earthquake stopped.

It still looked like the grassland outside, but the heavy atmosphere in the air filled their eyes with heaviness.

"Walk."

Without saying much, Dr. Main ran back into the room.

The entire volcano observatory has more than 60 seismometers installed near Katla volcano and Eyjafjallajökull, as well as dense sensors and magnetometers, which can accurately record all earthquakes.

After being busy for more than ten minutes, Ryan looked at the data on the monitor and said: "The total scalar seismic moment converted into moment magnitude Mw is about 4.8, the strike of fault node 1 is equal to 120°/the dip angle is equal to 30°/the slip angle is equal to 75 °; the trend of node plane 2 is equal to 310°/the inclination angle is 57°/the sliding angle is equal to 95°. The centroid depth of the waveform fitting is 9KM."

This was a magnitude 4.8 earthquake.

"..."

Dr. Main thought for a while and suddenly said: "Where is the phone? I need to contact the Meteorological Bureau."

"Uh, Dr. Main?"

"They should be able to find a Coast Guard plane, right? Let's go to the ice cap near Eyjafjallajökull to have a look."
