Scientists divided on causes of Palghar quake

first_imgPalghar district has seen thousands of small earthquakes since November 2018, but Friday’s quake measuring 4.3 on the moment magnitude (Mw) scale was the first time the magnitude crossed 4 here. Scientists, however, are divided on the primary cause of this phenomenon. Some believe it is related to groundwater levels, and others attribute it to tectonic activity. If high groundwater is the cause, the quakes may remain small. This phenomenon, called hydroseismicity, is common across the Deccan plateau. However, another hypothesis is that intra-plate tectonic forces could be generating stresses along faults in Palghar. Such a mechanism is believed to be behind the 1993 Latur earthquake. If intra-plate activity is the cause, Palghar could see larger, more destructive quakes.Till a while ago, seismologists believed the driver behind the Palghar activity was hydroseismicity. In this phenomenon, rainwater enters the faults in the earth’s crust. This increases pressure, which is released through small earthquakes. In 2017, after heavy rains, such a phenomenon occurred in Hyderabad’s Borabanda suburb. “It continued for a month and a half and stopped,” said D. Srinagesh, chief scientist at the National Geophysical Research Institute in Hyderabad. Such earthquakes typically measure less than 4 Mw and subside by December. They are also very shallow, typically emerging from within 4-5 km underground. In contrast, the Palghar quakes have continued into February, indicating that tectonic activity is at play, says Dr. Srinagesh. Also, a few of the temblors originated from 15 km underground, deeper than most hydroseismic quakes. With magnitude crossing 4 Mw this month for the first time, “all we can say is that disaster mitigation procedures should be set into motion,” he said.However, Vineet Gahalaut, Director of the National Centre for Seismology, New Delhi, said hydroseismicity couldn’t be ruled out yet. The Mw 4.3 quake was not necessarily significant, he said, because previously, quakes measuring Mw 3.7 had occurred. This small increment in magnitude was consistent with the ‘swarm’ pattern of hydroseismicity, he said. Further, according to him, the quakes were clustered within a small area, again a feature of hydroseismicity. Yet, he cautioned that it was impossible to discount tectonic activity as a cause.Previously, scientists had estimated that Palghar could see a “maximum credible earthquake” measuring Mw 6.5. The MCE is the largest quake that can occur in a region. All of Palghar’s buildings must be prepared for this, seismologists say, though the timing cannot be predicted.last_img read more

first_imgTop seed Somdev Devvarman assured India at least a silver medal in the tennis competition of the Commonwealth Games by storming into the men’s singles final with a straight set win over Australia’s Matthew Ebden here today.Somdev, ranked 97th, outplayed third seed and world number 165 Ebden, 6-3 6-1 in one hour and 11 minutes in the men’s singles semifinals at the Centre Court of the R K Khanna Tennis stadium.His next opponent will also be an Australian as the other semifinal is an all-Australian affair between second seed Peter Luczak and fifth seed Greg Jones.Unlike the previous matches, the semifinal featured long rallies but Somdev had strong enough legs and stamina to outlast his opponent.Ebden was coming into this match after playing an energy-sapping three-setter against British Joshua Goodall and perhaps had not recovered from the gruelling encounter.Nevertheless, he did pose some questions for Somdev but the Indian was equipped with enough answers.The match never rose to expected highs ever since Ebden dropped his serve in the first game. The Australian slowly picked up but Somdev gradually tightened his grip over the match.The Indian broke Ebden twice in both the sets. He is also in contention in the men’s doubles and is scheduled to play semifinals with Rohan Bopanna later in the dayWith inputs from PTIlast_img read more

first_imgMinister of Education, Rev. The Hon. Ronald Thwaites, says developing a wellrounded workforce,capable of fulfilling the demands of the global job market,is critical to nation building. To this end, he says one of the Ministry’s priority undertakings will be training persons with the requisite skills that will empower them to thrive in the 21st Century workforce/labour market. “One of our main goals is to articulate our educational and training systems toward measured and measurable workforce needs in the society,” he said. The Minister was speaking at the opening of the Human Resource Management Association of Jamaica’s (HRMAJ) conference, at the Wyndham Kingston Hotel on November  21. Rev.  Thwaites emphasised that  the creation of a ‘workforce needs projection’ is also paramount in identifying the jobs that will be needed in the future. He said this  venture will have to be a collaborative approach, and urged members of the HRMAJ to partner with the Government in identifying these areas. The Minister  pointed out that billions are spent on education each year, so the nation’s future leaders should be trained in areas deemed critical. Citing the importance of technical and vocational skills,  Rev. Thwaites said the local and international job markets are demanding persons with such training. He added  that there should be a balance between academic competences and technical and vocational skills. On another matter, the Minister underscored the need for students to be fluent in English Language, adding that this is critical for the country’s progress. “It is a reproach that a university has to have English classes. By the time you get to university, you are supposed to be adept in English, and there shouldn’t have to be any make up sessions in Mathematics either,” Rev. Thwaites said. He  said that  the intention of the Ministry is “to do it right the first time…to make sure that we do not continue to waste the probably $20 billion per year that we spend on education system, on remedial work, rather than on exceptional advanced work, which is what Jamaica really needs in order to be a leader in the global workplace.” Meanwhile,  President, HRMAJ, Michael McAnuff-Jones, suggested that there needs to be the development of a bilingual labour force as well as the development of incentives to retain jobs in the island. “As HRMAJ, we stand ready to share our experience with the Government on how we can tackle the threats to job preservation and job growth,” he added. The conference, which is slated to end on November 23, is being held under the theme: ‘Engage People: Gain Phenomenal Success’. It presents attendees with a diverse set of activities that will enrich their experience and provide useful leadership, people centric and innovative strategies for application on the job. The HRMAJ, formerly the Jamaica Association of Training and Development (JATAD), began in 1978 when a small group of training and development practitioners decided to form an association dedicated to the training and improvement of such professionals and practitionerslast_img read more
