Newspaper reports on Julián Adem's work
Essentially the same report by Alfonso Chardy appeared in several newspapers on Mexico's plans to install a seismological network. Although the headlines were different, the reports were almost identical. We note that a British reader will think the headline "Quake Detection Network Slated" has a very negative meaning while this was certainly not the meaning that readers of the American newspapers will take. The first eight reports, which are essentially the same, relate to the seismological network. We then give two earlier reports, one on ocean heat affecting weather and the last on the launch of man-made satellites. All ten reports contain quotes by Julián Adem.
1. Mexico plans quake detector.
Reference: Alfonso Chardy, Mexico plans quake detector, The Advocate (Newark, Ohio) (25 December 1974).
Mexico plans to install a new seismological network to pinpoint the centres of earthquakes five minutes after they occur anywhere in North and Central America and the Caribbean.
Julian Adem Chain, director of the National University's Geophysical Institute said in a recent speech:
"Mexico will be the first country in the world to establish a continental seismological network ... " His speech, to the annual Mexican Geophysics Conference here, was reproduced in the University Gazette.
He said once the network is installed, probably in the next two years, seismologists in Mexico will be able to detect an earthquake over an area estimated at nearly half a million square miles, including Alaska, Canada, the United States, Mexico, Central America and the Caribbean.
The current seismological office in Mexico covers only about 100,000 square miles, officials said.
"We have estimated that with the new network we will be able to obtain in less than five minutes the exact epicentre of any earthquake over 4 degrees on the Richter Scale in Mexico and surrounding territorial seas," Chain said.
He said that the epicentres of earthquakes measuring more than 5 degrees in North and Central America as well as the Caribbean will also be detected in less than five minutes.
At present the seismological office here, with two monitors operating, requires 15 to 20 minutes to detect an epicentre because of insufficient equipment, officials at the office said.
The Richter scale measures the ground's motion in a tremor. A tremor of 4 or 5 degrees is considered mild. One or 6 is deemed severe and one of 7 can cause widespread damage. The San Francisco 'quake of 1906 registered 8.3 degrees on the scale.
Hundreds of small to mild to strong earthquakes hit Mexico and Central America and the Caribbean every year, officials said. Some of these earthquakes' epicentres cannot be determined.
The worst earthquake to hit the region in recent history was the December 23, 1972, tremor that devastated Managua, Nicaragua , killing an estimated 10,000 people. An earthquake that hit south-central Mexico August 21, 1973, levelled scores of towns and left upwards of 700 people dead.
Chain, the university's geophysical expert, said the projected network would consist of four "trunk lines" or monitor stations around the nation that would gather data when a quake hits and send it through electronic equipment to two already existing reception centres in Mexico City.
With the data gathered by the monitors outside the Mexican capital, the two stations here will pinpoint the quake's epicentre through a system of coordinates. He said the system will not be able to predict an earthquake before it hits.
Some officials said the system would be comparable to the Boulder, Colorado, seismological station which can detect quakes around the world. But the Mexican version will be smaller and only regional, they said.
The network will also be able to detect quakes out at sea and pinpoint epicentres there to see tidal waves could affect land in the region that the system will cover, Chain added.
He said two of these earthquake monitors would be set up in the Mexican ports of
Mazatlan and Acapulco on the west coast.
"We will be able to send information to Mexican ports and also to Hawaii and Japan
so they can take precautions," he said.
The network may also be used to detect volcanic activity in Mexico and Central
America. As a bonus, it will also be constantly used to examine the subsoil of Mexico to find out its structure, Chain said. He added that such knowledge will help in the search for mineral and oil wealth as well as the discovery of geothermic vapour sources.

Reference: Ocean Heat May Change Weather, Oakland Tribune (Oakland, California) (14 July 1964).
When weather patterns are consistently abnormal, the ocean temperatures or unusual snow cover may be responsible.
The discovery of a link between snow cover or ocean temperatures and long term weather patterns was reported to a symposium on long-range forecasting here by scientists from the United States Weather Bureau, Suitland, Maryland.
Jerome Namais, head of the extended forecast branch, said he jag found an "amazing tendency" of the earth's land and water masses to interact with the atmosphere. Such interactions frequently cause unusual weather patterns for an entire season, he said.
Dr Julian Adem of the National University of Mexico said he had worked out a method of predicting the temperature for as long as a month or a season in advance using equations solved by computer.
Although computers are now used in making 30-day weather forecasts, their predictions are not based entirely on mathematical equations. The past experience of meteorologists is also a factor.

The man-made moons which will be launched into space during the International Geophysical Year will be visible from Mexico City with ordinary binoculars, a Mexican scientist said today.
Dr Julian Adem, vice-president of the Mexican Commission for the International Geophysical Year, said the public will be duly informed when the satellites are launched and the course they will take.
Scientific observations of the satellites will be made from the Tonantzintla Observatory in Puebla, which operates under the auspices of the National University of Mexico.
Dr Adem said pictures of recent eruptions on the surface of the sun are being taken and sent to Germany for interpretation.
He said some 396 Mexican scientists are taking part in Geophysical Year activities.
